Bench2016 - Benchmarking Water Supply Systems Austria
Besides maintaining and further improvement of the high quality standards, economic optimisation of the Austrian water supply is the basis for the public funding situation, for the customer satisfaction (high water quality, supply safety, pricing and service) and for the ecological targets of a sustainable water supply. The method of benchmarking - the systematic comparison of enterprises by performance indicators - helps in finding the optimisation potentials by accounting the best water supply utilities as benchmarks for each performance indicator or each process within the water supply utility. The experience of these benchmark utilities in how they reached their leading positions shall serve as "best practices" for other water supply utilities. Within this project the corporate benchmarking activities are being continued after the successful exercise of Stage B (72 participants, 50 % of Austrian water supply). For further information please see the project website www.trinkwasserbenchmarking.at

Active Condition Monitoring of drinking water systems
The research project deals with the issue of model-based leak-containment in drinking water networks. Drinking water distribution systems consist of a large number of hydraulic components and are typically monitored only by a small number of measurement devices. The hydraulic system therfore is underdetermined. The focus of the project is the reconstruction of the hydraulic status based on sensor signals and the use of statistical mathematics. Including a priori knowledge about expected system conditions (for example, damage forecast models, consumption monitoring, operation characteristics , ....) will be a central part of the mathematical model developed to localize leaks. One aditional aim of the project is to derive optimal solutions in terms of the required number and the optimised placement of hydraulic sensors in the water supply system.To verify the developed algorithms as well laboratory tests as field tests are held.

Drinking Water Treatment for Karstic Springs Case Study Weiz
A constantly growing and consuming population together with climate change is leading to scarcity of resources in many fields. Drinking water was, is and will be the most worth protecting and at the same time the most sensitive resource on our planet. The use of groundwater presents the best way for drinking water supply. However, clean water is getting less and polluted water has to be purified and developed. Especially karstic areas have a high potential for further development. The quality of karstic water can equal groundwaters quality. Occasionally karstic water reacts on rainfalls and snowmelts in different ways, thus it gets affected and needs a water treatment. Initially this thesis describes all current drinking water treatments. Furthermore it has a focus on the karstic water problem; therefore the water supply of Weiz is specified. The drinking water for Weiz and periphery comes from a vulnerable karstic area which is highly influenced by precipitation. The main karstic spring has to be purified constantly. An ozone treatment with a downstream sand filter, which has been operating since the 1970s is still the current practice. The ozone treatment constitutes an energy-intensive process and should be modernized. Within the design period a field test of an automatic backwashing filter system could be conducted. This thesis summarizes the experiences of the field experiment and evaluates the received data.

Districtcooling
In the last years an increase in temperature of the ground water body under the city centre of Linz could be observed. One main reason therefore is the thermal use of ground water for cooling of buildings and industrial processes with individual groundwater cooling systems. To derive solutions with positive effects on the groundwater situation different scenarios for future (district) cooling systems in the city of Linz are developed and investigated regarding their feasibility and influences on ground water temperature. The investigated scenarios comprise a null scenario, a central district cooling scenario with cooling water taken from the nearby Danube and a semi central scenario with ground water district cooling systems in several different locations. The project is funded by the provincial government of Upper Austria.

EcoStorma - Ecological Economical Stormwater Management
In cause of reduction areas for naturally infiltration existing combined sewers and rainwater channels will often reach their limits of capacity during heavy precipitation. In the future rainwater management has to be promoted by considering ecological, economical and social aspects, for efficiently using the existing sewage water system, for preventive flood protection, to remain and to improve the groundwater and surface water quality. In the literature (Austrian ÖWAV Regelblatt 35, German DWA-A138) there are different technical types of rainwater management in obedience of different influencing factors (for example pollution degree, soil conditions, groundwater level, space available etc.) described, as well as the dimensioning of theirs, but there exist no method to evaluate the measurements. The aim of the research project EcoStorma is to develop a method to evaluate rainwater measurements regarding ecological and economical aspects for an easy selection and implementing. The possibilities for flooding protection, the structural flooding protection and the rainwater management, will be shown in the research project HouSui - Flood Control Measures Model Study Bründlbach (Graz) Strategies for an Integral Urban Drainage Management by using simulation models. For an economic and ecological analysis we will investigate some different catchment areas from our project partners based on the study of HouSui. An environmental benefit will be reached by implementing storm water measurements and so special support schemes appear meaningful. In the context of the project EcoStorma we will develop concepts for community and state developments. The results of the project will be summarized in a structured catalogue for the implementation storm water management measurements in consideration of ecological and economical aspects.

SCHTURM - Micropollutant emissions of urban catchments out of waste water treatment plants, stormwater discharges and combined sewer overflows
Within the project Micropollutant emissions of urban catchments out of waste water treatment plants, stormwater discharges and combined sewer overflows (SCHTURM) organic and inorganic micropollutant emissions from several entry paths (effluent of waste water treatment plants, combined sewer overflows or stormwater discharges from urban areas and highways) to surface water and ground water bodies during storm events should be estimated. The aim is to estimate certain micropollutant loads from these entry paths for the whole of Austria for the first time to get a first estimation about the main entry paths of the investigated substances. In the selected catchments a sampling campaign to collect samples of whole storm water events should be accomplished. Furthermore a mathematical estimation of the discharged storm water and rain water loads is intended. This estimation should be done under specific assumptions for several scenarios. Based on the results combined with measurements in the defined catchments a quantification of the several entry paths for the whole area of Austria should be done. By this project general data should be generated to serve as a basis for decisionmaking.

ZuHaZu Condition and Risk Assessment of Transmisson Mains
Transmission mains are the most vulnerable parts of water supply systems. The state of the art in Austria due to condition assessment of water pipes is described in ÖVGW Guideline 105, 2010 "Failure Statistics". As given by the name of the guideline condition data generally is collected during the failure repair process. Based on this data statistical methods are used to describe future failure occurence, as a state of the art method for distribution pipes. Rehabilitation decisions are mainly based on this statistical failure prediction. This methods provide satisfying results for the supply system, but are not applicable for the transmission systems as here a failure providing strategy is necessary due to the high vulnerability of these pipes. Direct inspections of transmission mains are not common practice so far. Mainly because of short time cost calculations and technical restrictions due to inspectability of the pipes. The aim of this study is to investigate the possibilities and restraints of available transmission pipe inspection techniques or material tests of pipe segments, to derive practicable techniches and evaluate them due to their performance in practice (case study). Cost benefit ratios of different condition asesssment techniques on basis of life cycle cost calculations are part of the study as well. Further the study implements an integrated risk assessment (based on Friedl, et al 2011 and Möderl, et al, 2009) for an example transmission system (City of Vienna) to derive pipes with the highest risk of failure. The elaboration of an integrated failure risk asessment method has the aim to provide a decision support for condition inspection planning.

Vertiefende Rehabilitationsprioritätenermittlung für Versorgungsleitungen aller Ortsnetzbereiche des Wasserleitungsverbandes Nördliches Burgenland
Die lang- und mittelfristige strategische Rehabilitationsplanung, als Grundlage für den gezielten Einsatz der erforderlichen Reinvestitionen für Wasserversorgungsnetze, ist eine der wesentli-chen Zukunftsaufgaben von Wasserversorgungsunternehmen. Die Rohrnetze unterliegen einer Vielzahl von Einflüssen, welche die Verschlechterung und Alterung bzw. das Schadensverhalten der Leitungen und Armaturen beeinflussen. Eine wesentliche Basis hierfür ist eine ausführliche Dokumentation von Bestand und Zustand der Systeme. Darüber hinaus ist, von der Lage der Leitung abhängig, mit einem unterschiedlichen Gefährdungspotential (Schadensausmaß) durch einen Rohrbruch zu rechnen. Sowohl die Einflussfaktoren auf die Zustandsverschlechterung, welche die Schadenswahrscheinlichkeit beeinflussen, als auch die Größenordnungen des Schadensausmaßes, welche Großteils monetär definierbar sind, sollen daher zusätzlich in eine vertiefende Berechnung von Erneuerungsprioritäten mit einbezogen werden.

HouSui - Flood Control Measures Model Study Bründlbach (Graz) Strategies for an Integral Urban Drainage Management
In recent years, floodings in urban areas due to intensive stormwater events occurred more often and caused damages in industrial and residential areas, as well as on public goods. The aim of the project HouSui is to highlight possible causes and approaches for floodings in urban areas. On the one hand, the chief causes for floodings in urban areas are the systematic exploitation of rural infiltration grounds and on the other hand, the increasing surface sealing during the last decades within urban areas. In connection with climatic changes there is an accumulation of floodings in urban areas estimated. This raises, however, more and more the question for the right handling of these issues for municipal drainage management utilities, both for rural and urban areas. The enquiry, assessment and minimisation of flood risks in urban areas is a com-bined assignment for drainage management utilities on the county level as well as the municipal level. Furthermore, the municipal drainage management utilities have to align their assignments with other municipal infrastructure departments, such as the department of land use planning and urban development, wastewater discharge and road maintenance. The assignment of urban flood risk management has to be seen as a cross-linked one from all the departments involved. A cross-linked consideration offers the possi-bility to tie single measures (e.g. the on the spot infiltration of not contaminated rain-water according to the Austrian ÖWAV Regelblatt 35) in a way, which allows dis-covering and using synergetic effects. Detention, infiltration and the proper discharge of surface water in case of intensive stormwater events in rural and urban catchment basins are the main aims of water management in urban areas. The project HouSui wants to carve out strategies for an integral urban drainage management. The interactions between the surface run-off and the run-off in the sewer system are quite complex, thats why HouSui attempts linking 2D-surface model with a hydrodynamic sewer model. Single measures as well as synergetic packages of measures cannot only be mapped but also analysed concerning e.g. their impacts on the catchment basin and sensitivity. The aim of the modelling is to highlight the flow paths of rainwater in case of intensive stormwater events on surface and in the sewer system. There are various aspects that have to be considered for the assessment of meas-ures, such as regulatory framework (e.g. the Directive 2000/60/EC establishing a framework for Community action in the field of water policy, the Directive 2007/60/EC on the assessment and management of flood risks, the RIWA-T), technical guidelines (e.g. the EN 752, the ÖWAV Regelblatt 35, the ÖWAV Regelblatt 11), economical, ecological and sociological requirements. The main achievement of the project HouSui, where various packages of measures are pointed out, will be a compendium with recommended procedures entitled strategies for an integral urban drainage management valuable for all departments involved in the construction, duty and maintenance of any kind of urban infrastructure.

EU - Sudplan - Sustainable Urban Development Planner for Climate Change Adaptation
The SUDPLAN proposal aims at developing an easy-to-use web-based planning, prediction, decision support and training tool, for the use in an urban context, based on a what-if scenario execution environment, which will help to assure populations health, comfort, safety and life quality as well as sustainability of investments in utilities and infrastructures within a changing climate. This tool is based on an innovative and visionary capacity to link, in an ad-hoc fashion, existing environmental simulation models, information and sensor infrastructures, spatial data infrastructures and climatic scenario information in a service-oriented approach, as part of the Single Information Space in Europe for the Environment (SISE). It will provide end users with 3D modeling and simulation as well as cutting edge highly interactive 3D/4D visualization, including visualisation on real 3D hardware. The tool includes the SUDPLAN Scenario Management System and three so-called Common Services, which downscale regional climate change models using local knowledge, and which will be available for use in all of Europe. Both components will contribute to improved assessment of urban climate change impact. Vital aspects of climate change are considered in 4 carefully selected urban pilot applications located in Austria, the Czech Republic, Germany and Sweden. They cover such diverse applications as: a) extreme rainfall episodes causing problems with b) uncontrollable, extremely localized runoff, and c) for drainage and sewage systems, d) hazardous air pollution and high ambient temperature episodes causing health risks, e) social dynamics (movement of people) as function of climate change and quality of living. Through innovative ICT, SUDPLAN contributes to SISE, provides new perspectives for a distributed service market, reinforces European leadership in the research area and fosters the capacity to cope with climate change impacts in urban environments.

Vertiefende Untersuchungen zur Abschätzung der Beeinflussung der Trinkwassertransportleitung im Bereich Lagergasse/Puchstraße im Zuge der Baumaßnahme - Sanierung der Altlast ST 23 Alpenteer
Transportleitungen bilden in einem Trinkwasserversorgungsnetz die wichtigsten und entschei-dendsten Glieder der Versorgungskette, die zur Aufrechterhaltung eines ordentlichen Betriebes und einer optimalen Versorgung der Bevölkerung in einem Versorgungsgebiet dienen. Eine ungeplante Versorgungsunterbrechung, aufgrund eines Transportleitungsrohrbruches, kann zu einem Zusammenbruch der Versorgungssicherheit für ganze Teilbereiche eines Netzes führen und weiters zu großen Schadenskosten im Einflussbereich des Schadensortes führen. Es kann aufgrund dieses Gebrechens zu großflächigen Unter- und Ausspülungen der Straße und des angrenzenden Erdreiches kommen. Dadurch sind die Standfestigkeit von Bauwerken, Fundamenten und angren-zenden Einrichtungen gefährdet. Diese Vorfälle können komplizierte Gerichtsverfahren mit der Frage des Verschuldens nach sich ziehen. Daher muss es für ein Versorgungsunternehmen oberste Priorität sein den Einfluss auf Transportleitungen durch Einflüsse von außen minimal zu halten und alle möglichen Einwirkungen auf das Rohr und die resultierenden Auswirkungen für das Rohr vorher zu untersuchen und eine Entscheidung im Sinne der Versorgungssicherheit im Vor-hinein schon zu treffen. Besonders nachteilige Auswirkungen auf das Rohr können z.B. durch hohe statische und dynami-sche Lasten mit Krafteinleitung in der Nähe von erdverlegten Rohrleitungen sein. Daher sollen im Rahmen dieser Untersuchungen alle Einwirkungen auf das Rohr und alle Bauzustände in der Durchführung der gesamten Baumaßnahme untersucht werden.

RiskTrans - Risikobewertung von Rohrabschnitten eines Transportleitungsnetzes
Die lang- und mittelfristige strategische Rehabilitationsplanung, als Grundlage für den gezielten Einsatz der erforderlichen Reinvestitionen für Wasserversorgungsnetze, ist eine der wesentlichen Zukunftsaufgaben von Wasserversorgungsunternehmen. Die Rohrnetze unterliegen einer Vielzahl von Einflüssen, welche die Verschlechterung und Alterung bzw. das Schadensverhalten der Leitungen und Armaturen beeinflussen. Eine wesentliche Basis hierfür ist eine ausführliche Dokumentation von Bestand und Zustand der Systeme. Darüber hinaus ist, von der Lage der Leitung abhängig, mit einem unterschiedlichen Gefährdungspotential (Schadensausmaß) durch einen Rohrbruch zu rechnen. das Risiko welches von einer alternden Leitung für das wasserversorgungsunternehmen und deren Kunden ausgeht lässt sich durch Verknüpfung von Schadenwahrscheinlichkeit und Schadensausmaß ableiten. Sowohl die Einflussfaktoren auf die Zustandsverschlechterung, welche die Schadenswahrscheinlichkeit beeinflussen, als auch die Größenordnungen des Schadensausmaßes, welches Großteils monetär definierbar sind, sollten daher in eine vertiefende Berechnung von Erneuerungsprioritäten mit einbezogen werden.

ÖVGW Benchm 08 - Stufe C - OVGW Benchmarking 2008 - Stage C
Besides maintaining and further improvement of the high quality standards, economic optimisation of the Austrian water supply is the basis for the public funding situation, for the customer satisfaction (high water quality, supply safety, pricing and service) and for the ecological targets of a sustainable water supply. The method of benchmarking - the systematic comparison of enterprises by performance indicators - helps in finding the optimisation potentials by accounting the best water supply utilities as benchmarks for each performance indicator or each process within the water supply utility. The experience of these benchmark utilities in how they reached their leading positions shall serve as "best practices" for other water supply utilities. Within this project the corporate benchmarking activities are being continued after the successful exercise of Stage B (72 participants, 50 % of Austrian water supply). For further information please see the project website www.trinkwasserbenchmarking.at

OPTIMISCH - Optimized Design of Combined Sewer Facilities
The new ÖWAV Guideline 19 (Guideline for the design of combined sewer overflows) released in November 2007 presents new requirements for the design of combined sewer overflows (CSOs) in Austria. In future, hydrological long term simulations will be used for verification of CSO design and function. According to the guideline, an efficiency factor that is defined as part of the rainfall runoff that reaches the waste water treatment plant in long-time yearly average has to be reached. Within the OPTIMISCH project a guide for planners and sewer network operators will be created to show possibilities, advantages and limitations of the new guideline. On the basis of real case studies (existing sewer networks), hydrological model simulations combined with a thorough sensitivity-analysis will be carried out. A comparison of the obtained results with alternative design rules (ÖWAV guideline 19 (1987), ATV guideline A 128) will let us conclude what results we have to expect when CSOs designed according to the older rules are re-designed using the new ÖWAV guideline 19. In addition a comparison of planning and investment costs will be carried out. To increase universality of the results obtained within the OPTIMOSCH project, the selected case studies represent catchments with different properties (rural zones, urban zones, extensive sewer network....)

Investigation on Precipitation and Discharge in the Urban Research Basin Graz
In urban catchment areas the increasing urbanisation raises many problems for drainage. The successive growing of the development, the elimination of retention areas, the limited capacity of existing sewer systems and the elimination of receiving water change determine the runoff conditions. The sewerage inaccordance with growth has to be completed and extended. To get reliable values for design of sewers the observation of precipitation and flood events is required. By means of these data flood design events can be calculated using hydrological methods. That requires evaluation of the recordrd measuring data. in the urban catchment area of Annabach (0,74 km2), where the portion of garden amounts to 25 %, precipitation and water levels are measured and registered at some gauges. To design rating curves and to compute discharge hydrographs discharge measurements are carried outperiodically.

IWA-AWWA Manual of Best Practice "Benchmarking Water Services"
Benchmarking has become a key tool in the water industry to promote and achieve performance targets for utilities. Utilized as an instrument for performance improvement through systematic search and adaptation of leading practices, benchmarking activities have expanded globally. Nowadays, many projects are being carried out worldwide to meet different needs and objectives, in varying contexts, with outstanding results and impact. However, despite the many projects, published papers and ever growing interest in this field, the terms and concepts used by the industry are far from being consistent. This manual of best practice is edited by the Task Group on Benchmarking (a joint effort of the Efficient Operation & Management Specialist Group and Statistics & Economics Specialist Group of IWA, the International Water Association) and commonly published by AWWA and IWA Publishing. The manual provides valuable information to those planning to get involved in a benchmarking project and even to experienced practitioners. The objectives of this manual are to define a new framework in which the traditional benchmarking concepts can be clearly distinguished, guaranteeing more fluent and efficient communication. The manual intends to be a hands-on document, with a practice oriented approach, both from the perspective of those organizing a project, as well as the needs of potential participants and even beginners in the topic. This practical how-to information originates in the experiences gathered in some of the most relevant benchmarking projects in the water industry to date, including the IWA-WSAA benchmarking efforts, the European Benchmarking Co-operation and the several benchmarking projects carried out in Austria and Central Europe.

Optimierung bestehender Aufbereitungsanlagen für huminstoffreiche Wässer im Waldviertel
Im nördlichen Waldviertel gibt es zahlreiche Wassergewinnungsanlagen deren Wässer durch niedrigen pH-Wert, hohen Eisen- und Mangangehalt, hohe Oxidierbarkeit, hohen SAK (Spektraler Absorptionskoeffizient) und teilweise hohen Huminstoffgehalt gekennzeichnet sind. Zudem kommt es häufig zu Beeinflussungen durch Oberflächenwässer, was immer wieder hohe mikrobiologische Belastungen nach sich zieht. Als gängiges Desinfektionsverfahren kommt bislang häufig eine Chlordioxid-Dosierung zum Einsatz. Durch die Behandlung der Wässer mit Chlordioxid besteht die Gefahr, dass sich aus den Huminstoffen gesundheitsschädliche Desinfektionsnebenprodukte bzw. Substrate für Wiederverkeimungen im Rohrnetz bilden. Auf dieses Risiko wurde auch schon von Behördenseite hingewiesen. Im gegenständlichen Projektvorhaben sollen Optimierungsmöglichkeiten von bestehenden Aufbereitungsanlagen für solche Wässer unter anderem durch den Einsatz der Ultrafiltration (UF) in technischer und betriebswirtschaftlicher Sicht untersucht werden. Dabei sollen v. a. folgende Punkte geklärt werden: - Was ist die optimale Abfolge der erforderlichen Aufbereitungsschritte (pH-Einstellung, Enteisenung, Entsäuerung und Aufhärtung, Fällung bzw. Flockung, UF, Desinfektion)? - Welcher Wirkungsgrad kann bei der Huminstoffentfernung erzielt werden? - Wird mittels UF der SAK bzw. die UV-Durchlässigkeit soweit gesenkt, dass anstatt der Chlordioxid-Dosierung eine Desinfektion mittels UV-Bestrahlung erfolgen kann? - Werden mittels Fällung bzw. Flockung in Kombination mit UF Keime ausreichend zurückgehalten, sodass abschließend keine Desinfektion erfolgen muss? - Ist die Methode der UF zur Umsetzung bei der Vielzahl an relativ kleinen Wasserversorgungsanlagen im Waldviertel geeignet und welche Rahmenbedingungen müssen erfüllt sein? - Welche Betriebskosten entstehen im laufenden Probebetrieb und welche Investitions- bzw. Betriebskosten sind im großtechnischen Einsatz zu erwarten?

Data Collection Manual for the OECD/Eurostat Joint Questionnaire on Inland Waters (Lot 2)
The Questionnaires on the State of the Environment are an attempt to set up world-wide coherent data collections on the main environmental issues. The data collection was first established in 1980 by OECD, and Eurostat joined this exercise in 1988. The UN Statistical Division set up an environmental data collection on a more reduced level but entirely compatible with the Joint OECD/Eurostat Questionnaire. The Questionnaire on Inland Waters is one of the nine questionnaires and covers one of the most sensitive environmental topics. The Data Collection Manual (version 1.0) was established by Eurostat in 2004 in order to provide guidance, best practices and standards in collecting, estimating and compiling the data required by the Joint Questionnaire. It delivers a comprehensive description of the terminology and methodology for water statistics including the different natural and anthropogenic processes in the water cycle, from internal resources generation to water abstractions and discharges. Based on version 1.0 and users-feedback, an adapted version (version 2.0) of the Data Collection Manual was established in 2006. This new version takes users feedback into consideration and aims at providing more user-friendliness. Among others, one focus of the Data Collection Manual (version 2.0) is the provision of detailed numerical examples. The project participation of Graz University of Technology (Institute of Urban Water Management) concentrated on data aquisition aspects of public water supply (tables 2 & 3 in the Joint Questionnaire).

Benchmarking ÖVGW - Stufe B - Benchmarking and Best Practices in the Austrian Water Supply - Main Project "stage B"
Besides maintaining and further improvement of the high quality standards, economic optimisation of the Austrian water supply is the basis for the public funding situation, for the customer satisfaction (high water quality, supply safety, pricing and service) and for the ecological targets of a sustainable water supply. The method of benchmarking - the systematic comparison of enterprises by performance indicators - helps in finding the optimisation potentials by accounting the best water supply utilities as benchmarks for each performance indicator or each process within the water supply utility. The experience of these benchmark utilities in how they reached their leading positions shall serve as "best practices" for other water supply utilities. Within this project the benchmarking system has been further improved upon the experiences of the pilot project "stage A". A benchmarking process is now being carried out with 68 water supply enterprises. For further information please see the project website www.trinkwasserbenchmarking.at

Design depth of precipitation in urban water management
The Autrian ÖWAV guidelines concerning the sewer design and the storm water management are being revised. Therefore a project called ÖKOSTRA was initated to develop regional IDF curves (intensitiy, duration, frequency) for the design work of Austrian sewer structures. Processed material or digitalised precipitation values are put in a data bank and the amount of a certain design value of precipitation hN for the requested duration D and the return period T can be investigated according to the ÖKOSTRA guidelines. Since the end of the project it is possible to get regional IDF curves for the densely populated aereas in Austria (places with more than 5000 inhabitants).

Combined Sewer Overflow Emissions Modeling for the Sewer Catchment Area Graz-West
The aim of this diploma thesis is the modelling and calibration of a CSO of the sewer-catchment area Graz-West. After the calibration a long-time simulation was calculated with long-time precipitation series. With the long-time simulation and its analysis the influences of the different input parameters on the result were shown. The influence of the minimum discharge rate in accordance with the Austrian draft of stormwater regulation was analysed too. The CSO was modelled with the software KOSIM. The input data are from the sewer-online-monitoring-station Graz. The main problem of the modelling was the right reproduction of the spillflow behaviour of the CSO. The verification of the model was realized by means of a three months period. The long-time simulation showed results in a wide range compared each single year. The minimum values of discharge referred to the AEV Mischwasser draft could be kept. Analysis resulted paved area, end run off coefficient and rain weather concentrations as main influence factors. Therefore, these input values have to be determined exactly.

Quantification of Pollution Loads from a Combined Sewer Overflow into a Receiving Water
Within the scope of the Austrian research project Innovative Technology for Integrated Water Quality Measurement an online sewer monitoring station has been installed at a combined sewer overflow in Graz. The main goal of this since October 2002 operated measurement station is the quantification of the overflowing pollution loads into the river Mur by means of online techniques. In this thesis all overflow events during the period from October 2002 until January 2004 were analysed. Frequency and duration of the overflow events into the receiving water and the resulting overflowing pollution loads of Chemical Oxygen Demand (COD) and Total Suspended Solids (TSS) have been evaluated. Another assignment was to operate and to continuously optimize the sewer monitoring station during this period. During some overflow events parallel laboratory analysis had been made to validate the online measurements.

Comparison and Calibration of Different Discharge Measurement Methods
Discharge is one of the most important physical values in the fields of water management but unfortunately not directly measurable. Therefore different methods have been investigated to measure this value. This diploma thesis deals with the calibration and the comparison of different discharge measurement methods and their reliability in practice. Therefore comparative investigations and calibrations were carried at a natural stream in Western Styria and in the sewer system of Graz near a combined sewer overflow by using different reference methods.

PiReM - Pipe Rehabilitation Management - IRM
The Project PiReM is divided in three parts: Task 1: further development of the long-term rehabilitations strategy Task 2: further development of the mid-term rehabilitations strategy Task 3: upgrading with a hydraulic net analyses / scenario analyses The existing software PiReP - Pipe Rehabilitation Planning System is a decision support system for supporting the planning of rehabilitation steps on water pipelines and will be upgraded in the project. PiReP supports by using two modules, the long-term rehabilitations strategy and afterwards, but separately, the mid-term rehabilitations strategy by calculating rehabilitation priorities. In Task 1, the long-term strategy will be upgraded by using new statistic and macroeconomic developments for optimization of the rehabilitation steps. Task 2 focuses on implementing business management aspects for optimizing re-investigations into the decision support. By adding the economic to the technical data as well as a connection to a geographical information system, PiReP can be used as an integrated tool for rehabilitation management. In Task 3 the developments focuses on the influences of hydraulic capacity compared with scenario analysis like essential supply to the rehabilitation plan.

Probability Assessment of Spill Flow Emissions
Real time control will get more important to reduce CSO emissions. Most of the already existing real time control strategies minimize spill flows from the viewpoint of volume minimization. For receiving water the reduction of emissions is much more important. Measured waste water data and probabilistic approach of these data are the focal points in this research. With an UV-VIS spectrometer installed in a swimming pontoon absorption is measured directly and constant. Based on absorption measurements waste water time series curves of COD, TSS and nitrate are shown. A forecast of CSO emissions and the adjustment of ANN for the control system will be the next step included for this project. By statistical evaluation of rain and measured waste water data as well as forecast of CSO emissions with ANN, spill loads can be reduced. The results of this research are basis for future real time control of CSOs in Graz (Austria).

Innov Messtech in d Wasserwirt - Novel Technology for Integrated Water Quality Measurement (IMW2)
With the release of the EC water framework directive, water quality management will become a transnational issue on a catchment scale, requiring exchange of water quality data between governing boards and water authorities of the different member states. One issue for water quality management is to have sufficient and comparable information about the water quality and the impacting factors and effectiveness of measures taken. Based on novel technologies, a modular monitoring station suitable for continuous application in sewers, waste-water treatment plants and surface water bodies has been designed. The monitoring stations serve as the backbone of a water quality pilot network, that is currently tested at different locations in Austria. The network also includes a central data base server, where the collected data is processed consistently and stored in a standard format. The water quality network design shows new perspectives with respect to continuous and consistent water data collection and processing, which is a prerequisite for decision making in water quality management. Our part in this project is to run monitoring stations at combined sewer overflows (CSO) where we want to measure frequency and duration of spill flow events and to quantify the overflowing pollutional loads into the watercourse.

Hydrogeological Foundation for a Sustainable Use of Deep Groundwater in the Area of Eastern Styria and the Pannonian Basin (NANUTIWA)
Deep groundwater of the thick sedimentary rocks of the East-Styrian and the Pannonian basin are presently used and will be used as drinking water on a large scale both in Austria and in the border region of Hungary. For a goal-directed and long-term resources management the present knowledge is not sufficient in spite of the extensive development regarding the delimitation and characterization of the deep groundwater system, the available resources and their recharge. The present investigations aim at the development of the technical basis for a sustainable use of the deep groundwater by the water resources management for drinking water on the basis of existing knowledge. On this occasion the following questions should be settled: spatial delimitation depending on depth of connected aquifers; quantitative estimation of the available resources in the aquifers declared as connected; exploration of the location of the catchment areas of the aquifers; exploration of the space-time distribution of ground water recharge; development of the hydrogeological (conceptual) model; calculation of the water balance of the deep groundwater considering the current utilization; estimation of the potential maximum yields in the aquifers seen from the point of view of sustainable resources management; building of a measuring network for a continuous monitoring of the deep groundwater and data banks. The result should serve for the basis of a border-crossing management concept.

Studies on Aerobic Digestion of Sludge in Intermittently Aerated Activated Sludge Plants in Connection with Low Temperatures in the Activated Sludge Tanks
In the past, activated sludge plants with intermittent aeration and simultaneous aerobic digestion were designed like activated sludge plants with continuous aeration, i.e. pauses in aeration were not considered. Scale bench tests on SBR-plants and a temperature about 20 degrees celsius in the activated sludge tanks were made. The result showed, that even during the idle period the microorganisms are supplied to some extent with oxygen by the oxygen present as nitrate in the settling sludge, at least some of the idle period could be included as reaction time as well. Now we want to make further scale bench tests on SBR-plants with low temperatures in the activated sludge tanks. The result of these tests should show the influence of intermittent aeration in connection with low temperatures on aerobic digestion of sludge.

Decision Support Systems in Rehabilitation Planning of Water Pipe Networks
The pursuance of a preventive strategy in the planning of rehabilitation measures requires a detailed inventory as well as state analysis of the existing water pipe network. Once they have been adjusted accordingly, data management systems, such as relational data bases and geo-information systems, can serve as valuable tools in decision making. To locate weak spots in water pipe networks and, as a consequence, to plan their rehabilitation based on their current state, a desktop GIS was employed as decision support system. The data of the urban water pipe network of the city of Graz were available for the study. A crucial part of any comprehensive rehabilitation scheme is the assessment of the long-term need for rehabilitation. To this end, the ageing model according to HERZ was integrated into an Access data base. It provided the mathematical foundation of the decision support system PiReP (Pipe Rehabilitation Planning System), which was developed in the course of the study. It can be used for the administration of inventory data and recorded damage, the grouping of pipes displaying similar fatigue behaviour, the determination of trends in failure rates as well as for the calibration of ageing functions of groups of pipes, long-term rehabilitation requirement forecasting and scenario analyses.

Studies on Aerobic Digestion of Sludge in Intermittently Aerated Activated Sludge Plants
In the past, activated sludge plants with intermittent aeration and simultaneous aerobic digestion were designed like activated sludge plants with continuous aera-tion, i.e. pauses in aeration were not considered. However, according to the amended ATV - Merkblatt M 210 -, only times when aera-tion or stirring do take place count as reaction time, which - depending on the idle period - requires a larger volume of the activated sludge tank. But since even during the idle period the microorganisms are supplied to some ex-tent with oxygen by the oxygen present as nitrate in the settling sludge, at least some of the idle period could be included as reaction time as well. To explore this in more detail, the degree of aerobic digestion of activated sludges was determined in a bench-scale test unit with continuous and intermittent aeration. The results showed that up to pauses in aeration of 15 hours per day there is hardly any difference in the degree of aerobic digestion of sludges.

The Biodegradable Organic Carbon in Wastewater Engineering BTOC and BDOC as Alternative to BOD
During the last years there are many reasons why the determination of COD has fallen into disrepute for being the standard dimension in quantifying the organic matter of wastewater. Therefore the COD should be replaced by the TOC. The present thesis makes an critical view at the existing TOC-standards, gives an overview of the state of art concerning TOC-measuring und describes the experiences of the author in dealing with TOC-analysers. Beside it a simple biochemical method for determining biodegradable organic carbon (dissolved - BDOC or total - BTOC) which is applicable to wastewater is proposed. The described method is based on the known methods for the determination of aerobic biodegradability of organic compounds in water. By knowing the biodegradable fraction of carbon in wastewater an adequate and more reliable alternative to BOD is existing as well.

Investigations in the Hydrological Research Basin of Pöllau (Eastern Styria)
In the framework of the International Hydrological Program 1978, the building of the hydrological reserach basin in the inlet of Pöllau at Hartberg (East-Styria) was started. This measuring network for research purposes is operated by Graz University of Technology and the Hydrological Service of the Styrian Government. The hydrological research basin (58,3 km2) is equipped with measuring instruments for time invariant precipitation self-recording (precipitation gauge using tipping bucket and the weighing principle). Bubble gauges as well as pressure probes equipped with digital recording systems, are used for water level measurement. At the moment 7 rain gauges and 5 discharge gauges and a meteorological station are available. At the meteorological station precipitation, air temperature and pressure, relative atmospheric moisture, soil temperature in several depths, albedo, evaporation, wind direction and velocity are continuously measured and registered. The precipitation is measured by different principles (tipping buckets and electronic weighing) and in different heights (standard height and terrain height). At the water level gauges, discharge measurements are periodically carried out in order to prepare current rating curves.

Investigation on Precipitation and Discharge in the Urban Research Basin Annabach/Waltendorf (Graz)
In urban catchment areas the increasing urbanisation raises many problems for drainage. The successive growing of the development, the elimination of retention areas, the limited capacity of existing sewer systems and the elimination of receiving water change determine the runoff conditions. The sewerage inaccordance with growth has to be completed and extended. To get reliable values for design of sewers the observation of precipitation and flood events is required. By means of these data flood design events can be calculated using hydrological methods. That requires evaluation of the recordrd measuring data. in the urban catchment area of Annabach (0,74 km2), where the portion of garden amounts to 25 %, precipitation and water levels are measured and registered at some gauges. To design rating curves and to compute discharge hydrographs discharge measurements are carried outperiodically.
