Operation and Maintenance for safe drinking water Kirsten de Vette International Water Association Tuesday 2nd of November 2010

Overview O&M challenges in the region Objectives of the workshop Agenda for today’s workshop

Operation and maintenance challenges of the region Intermittent supplies Rarely systemic quality monitoring of ground and surface water is undertaken Non Revenue Water Lack of leakage detection No replacement of pipes Absence of accurate databases intermittent water supplies is a key concern in many South East Asian cities resulting in problems such as water contamination and wastage, unreliable metering and possibly burst pipes due to the development of hydraulic water hammers. Additionally, ground water is overexploited lowering groundwater table and causing a shift to surface water. The surface water often faces pollution from agricultural and industrial practices. In the meanwhile, there is a lack of systemic quality monitoring of the water sources. Furthermore, often there is no systemic Non revenue water reduction. Deficiencies and lack of metering make the proper assessment of water production and consumption and examination of NRW and operational efficiencies difficult. Additionally, regularly O&M does not include leak detection, replacement of leaking worn-out, corroded and polluted pipelines.Maybe any of you even see more O&M issues in the region. In many countries these challenges have been understood and the countries are putting a greater emphasis on urban water safety.

Meanwhile South East Asia experiences 604,000 deaths from diarrheal diseases in South East Asia 2002 (The World Health Report, WHO, 2004) nonrevenue water (NRW) averages 30% of water production, but ranges from 4% to 65%, posing as a deterrent to the recovery of production costs. (ADB, 2006) sanitation and hygiene behaviour have much higher connections with transmission of diarrhoeal disease ADB study of 18 Asian utilities revealed that only 76.5% of connections are metered . Utilities in Asia particularly have every reason to worry about water losses—they lose up to 65% of their production daily, with most utilities averaging a 30% loss.

Objectives of the workshop Support the development of a framework which can be used to improve operational monitoring by service providers Identify research needs, knowledge gaps and capacity building needs in order to achieve this.

Agenda for today Session 1 Introduction to O+M issues related to water quality objectives 09.20 – 09.50 Operational and maintenance aspects of Water Safety Plans 09.50 – 10.20 Water quality monitoring aspects of Water Safety Plans 10.20 – 10.40 Break Session 2 Monitoring and institutional development to achieve safe drinking water 10.40 – 11.10 Improving system performance through the process of operational monitoring 11.10 – 11.40 Institutional development to achieve water quality improvements 11.40 – 12.30 Working group discussions 12.30 – 14.00 Lunch Session 3 OMN knowledge gaps and priorities for capacity building 14.00 – 14.40 Presentation from working groups 14.40 – 15.20 Plenary and facilitated discussion on knowledge gaps and priorities for capacity building 15.20 – 15.30 Workshop closure workshop will focus on practical aspects of operation and maintenance identified by Water Safety Plans. We will focus on the ways in which operational monitoring procedures and institutional development can contribute to improved water quality and identify your needs for additional resource materials and training.
