Benefits of Reducing Non-Revenue Water

• it can significantly improve cash flow and financial viability of utilities.
• It enables more people to have access to water connections, and at a higher quality of service, with existing resources.
• it reduces greenhouse gas emissions per unit of water delivered, which promotes climate resilience.

Free information on effective water leakage and pressure management in public water distribution systems, using proven practical concepts developed by Allan Lambert and other international experts in the IWA Water Loss Specialist Group. These methods have been successfully applied since 2000 in an ever-increasing number of countries, often through the use of free software designed for international application, with outreach, international support and more.

As Asia rapidly urbanizes, providing water and sanitation services has become problematic.

Most developing country governments in the region cannot deliver the required services themselves, and the private sector is reluctant to invest due to the risks and low returns, especially for sanitation. Public–private partnerships in water supply and sanitation have had mixed results, making sustainable sanitation a particularly challenging problem.

This tool provides guidance on the process and practices of benchmarking a water utility to understand the severity of NRW. The tool has evolved from work done by the Water Loss Specialist Group of the International Water Association, USAID and the InterAmerican Development Bank.

Results

• Reduced NRW by 198 million liters per day (MLD), equal to 10 percent of total water production for the city at the start of the contract

• Repaired more than 11,000 leaks

• Replaced 119,000 customer meters

• Avoided capital expenditure on alterna- tive water supply sources. Using typical benchmark costs, a new supply of 198 MLD could have cost around $200 million (compared to the NRW-PBC cost of $110 million)

• Earned additional revenue from the sale of the water saved
