14th European Water, Wastewater and Solid Waste Symposium * Proceedings Symposium No. 1 3

Sustainable Water Management in Response to 21st Century Pressures

Please join us at IFAT 2008: Sustainable Water Management in Response to 21st Century Pressures; the third in a series of specialty conferences held in partnership by the European Water Association (EWA), the Japan Sewage Works Association (JSWA) and the Water Environment Federation(WEF).

Managers, planners and designers in water management are already dealing with a number of pressures such as new regulations, increases in water usage, greater demands in terms of risk avoidance, and changes in populationdemography. But now it is obvious that the changes in weather bring new pressures. This conference is focussed on the practical consequences of the changes and how these can be mitigated and accommodated.

The European Water Association (EWA)

The European Water Association (EWA) is an independent non-governmental andnon-profit making organisation promoting the sustainable and improved manage-ment of the total water cycle and hence the environment as a whole.

It is one of the major professional associations in Europe that deals with the wholewater cycle; wastewater as well as drinking water and their associated treatmentwastes. With member associations from nearly all European Countries, EWA inclu-des most of the current European Union Member States as well as Norway andSwitzerland. Today, EWA consists of 25 European professional organisations each leading in their respective coun-tries, representing professionals and technicians for wastewater and water utilities, academics, consultants and con-tractors as well as a growing number of corporate member firms and enterprises. EWA thus represents more than50,000 professional individuals working in the broad field of water and environmental management. It is recognised bythe European Commission as a source of unbiased expertise.

When formed in 1981 its aim was to provide a forum for the discussion of key technical and policy issues affecting thegrowing European region. This it continues to do through conferences, workshops, meetings and special workinggroups of experts all organised on an international basis together with regular publications.

EWA is already a respected consultee on EC committees and, as and when appropriate, publishes opinion papers ontopical issues e.g. The Consequences of Climate Change, and The Management of Treated Sewage Sludge.

Now, in addition, it aims to contribute to a much greater extent to the development and implementation of Communityenvironmental policy and legislation.

The EWA is also exporting the European experience more widely. It has cooperation agreements with WEF (Water Environment Federation, USA), JSWA (Japan Sewage Works Association, Japan) and IWA(International Water Association, UK). In addition, in the Middle East, EWA is consultant to the Arab Countries Water Utilities Association (ACWUA).

The EWA Standing CommitteesFrom the very beginning the Association laid emphasis on the exchange of information and knowledge between pro-fessional experts. Through this exchange of knowledge, the EWA contributes to a sustainable water management:safe water supply and the protection of water and the environment. This was achieved by the organisation of nume-rous conferences and workshops taking place all over Europe and covering a very broad range of water related topicssuch as European legislation (themed areas such as Water Framework Directive, Groundwater Sewage SludgeDirective etc.), technical questions like for example the significance of small wastewater treatment plants in ruralareas, or scientific conferences, like Waters in Protected Areas and other integrated approaches. The European WaterAssociation organizes conferences and symposia at regular intervals, on events like the International Trade Fair forWastewater and Waste Disposal (IFAT) in Munich, Aquatech in Amsterdam but also its own annual EWA Brusselsconference. An increase in the number of members from Central and Eastern Europe (accession countries), has rai-sed the interest for events dealing with water protection issues.

However, not only conferences and the reports thereof were and are the output of the Association's work, but alsopublications.

All this work is achieved through the different Committees and Working Groups that were established from the verybeginning, but are adapting their scope according to the needs. They are based on voluntary work of experts comingfrom the different National Member Associations and working together on various subjects of current interest in thewater and environmental field.

The Editorial Committee (EdC)For an interim period this committee was also known as Communication Committee (CC). The Editorial Committee's(EdC) main assignment was the production of the printed journal "European Water Management Online". Its main taskis now the coordination of the newly established online journal "E-WAter" which is directly accessible via EWA'shomepage at www.EWA-online.eu at no extra cost. This online journal is officially registered and has its ownInternational Standard Serial Number (ISSN).




E-WAter is the electronic journal of the European Water Association. E-WAter is specifically targeted at Europeanpractitioners and researchers. It provides a forum where articles presenting and discussing technical views and experiences of European authors in every domain of water management may be published. All topics within watermanagement can be interesting for the wide scope of the EWA audience: design and construction procedures, operation & maintenance, monitoring, legislation, etc. concerning natural waters, drinking water, wastewater and related wastes.

Chairperson of the EWA Editorial Committee is Dr. Maria Helena F. Marecos do Monte at EWA.

The European Water Management News (EWMN) compiles news from the European and international water sector. This weekly news service currently reaches over 5,500 readers and is produced by the Netherlands WaterPartnership (NWP) for the European Water Association. Interested persons can subscribe for free by sending an e-mail to [email protected] with "Subscribe European Water Management News" in the subject line.

European Policy Committee (EPC)The committee follows the work of the European Commission and arranges regular meetings with officials in theCommission, responsible for activities of relevance to water management. The committee gives comments and adviceto official European institutions on behalf of its members. The EWA is attending meetings of the Strategic Co-ordina-tion Group under the WFD Common Implementation Strategy. Furthermore the EWA is in close contact with otherEuropean associations and institutions.

The objectives and responsibilities of the European Policy Committee (EPC), under the guidance of the governingbodies of the European Water Association, and within its rules of procedure, are the following:

• Organise and coordinate relationships of EWA with European level bodies, and especially with bodies of theEuropean Union;

• Facilitate and create the necessary and useful flows of information amongst the persons and groups representingEWA towards European level bodies, as well as between the former and the National Associations (NA), membersof EWA;

• Identify emerging issues and important trends in water related European policies and issues, which are of interestto EWA and its members, in order to allow EWA to anticipate future changes and to contribute efficiently toEuropean policy development;

• In consequence, and in conjunction with the European Technical and Scientific Committee (ETSC), propose theevolution of thematic activities and actions of EWA.

European Technical and Scientific Committee (ETSC)The ETSC provides a focal point for communication and co-operation between European practitioners and researchers concerned. Under the ETSC several working groups are organised. These working groups are installedaccording to the needs of the association. Currently there are working groups on: Climate Change, Groundwater,River Morphology, Sewage Sludge and Sustainable Flood Management. The work results in technical and scientificpapers and documents.

The committee is also responsible for the organisation and sponsorship of workshops, seminars, conferences andsymposia.

The Japan Sewage Works Association (JSWA)

1. IntroductionStarting in the latter half of the 1950s, rapid growth of industrial economy led to such social pro-blems as aggravation of the living environment and water pollution in public water bodies. Thiswas the situation when the Sewerage Division of the Japan Water Service Association and theNational Sewage Works Development Conference were integrated to form the Japan Sewage

Works Association in April 1964. JSWA got permission to establish itself as a public interest corporation in January1965 and began full-scale activities with public organizations as regular members. The Association's objectives are to develop sewerage services soundly, while conducting research on sewerage systems, and to preserve public waterbodies for the improvement of people's lives. As a network organization of bodies involved in sewage works, JSWAcarries out a wide range of activities to promote development of sewage works, and facilitates communication andcooperation between public organizations implementing and planning sewage works on the one hand, and Nationalgovernment, related organizations, enterprises and civic groups on the others.

2. MembershipJSWA has 1,570 organizations implementing or planning sewage works as regular members, 71 as associate mem-bers, 1,309 enterprises as supporting members, 497 as individual members and 7 honorary members, for a total of3,454 organizations and individuals as of January 1, 2008.

3. ActivitiesJSWA carries out a wide range of activities to promote the sewage works. The four main categories of activities are:
