WATER LOSS IN ASIA
The need for NRW management in general, and in Asia in particular, is so obvious that it is hard to understand why efforts to improve the situation have been so limited. There are, however, a few successful examples of utilities reducing NRW to below 20% (e.g. Singapore, Osaka, Manila [East Zone])(see illustration on right) and some places where serious actions have at least started. However, the vast majority of water utilities in Asia are not engaging in serious and professional NRW management. For many cities, reducing NRW should be the first option to pursue when addressing low service coverage levels and increased demand for piped water supply. Expanding water networks without addressing water losses will only lead to a cycle of waste and inefficiency.
WHY NRW IS NOT ADDRESSED
- Lack of understanding of the link between asset management and NRW
- Lack of technical expertise and equipment.
- Insufficient knowledge of NRW benefits
- NRW is usually covered by an inadequate budget
- Subsidy or absence of raw water pricing
- Subsidised tariffs and lack of cost recovery
- Lack of political will, sometimes linked to corruption, vested interests and ignorance of benefits
