Abstract:
This book provides stakeholders in Southeast Asian urban water supply and sanitation with a point of reference and tools to improve development and operational performance.
In the section on water sources and water resources, there is much to learn from Singapore. Its government has given top priority to water among its policies and has shown the way by recycling water and putting water and sanitation under one roof from source to disposal/reuse. In many other countries, there are often “too many cooks” looking for a piece of the water sector pie. Strong and consistent leadership over the long term is shown to be an important factor in the success of utilities.
The chapter on service coverage highlights the importance of a recent decision made by Viet Nam to abolish connection fees for urban water supply, allow these costs to be funded by loans amortized over several years, and increase tariffs marginally for all, to pay for these loans. This book encourages all utilities (both public and private) to follow this good example. At the same time, we see the need for social engineering in each utility to make sure the urban poor are properly provided for.
In the discussion on tariffs, we learn the importance of maintaining the financial viability of the utility and the autonomy of management through appropriate tariffs. We also learn that it is best for the utility to seek first the customers’ endorsement of tariff increases before approaching the government for formal approvals. A transparent tariff policy will be easier to implement.
Nonrevenue water (NRW) can be tackled through managing distribution at the lowest practicable level. But always the “cause” must be identified and treated. We see how successful NRW reduction is a win-win activity because it not only reduces losses but frees up more water for new connections (paying customers), thus circumventing water source issues at least for the time being. In the home, we see how advisable it is for the utility to go beyond the meter and help customers reduce their own water losses. With the support of ADB, water operator partnerships (between strong and weak utilities) are now flourishing and improving the performance of weak utilities, through peer-to-peer knowledge transfer.
