The TORs are designed to be used as part of an NRW-reduction project being implemented in accordance with the NRW Manual. It is assumed that the consultant will be engaged after an Initial Assessment (and if needed, a Field Assessment) of the utility and relevant networks have been completed (see Section 5 of the Manual). That assessment will have gathered information on the Water Balance, assessed whether NRW control is needed, whether a performance-based contract is appropriate, and what the goal of the contract should be.
Operational Manual: Global Program on Developing Good PBC Practices for Managing NRW, The World Bank, December 2016. The Operational Manual describes the process for planning and implementing non-revenue water (NRW)-reduction projects, specifically through Performance-Based Contracts (PBCs). It focuses on the process and key decisions to be made.
The mission of the Kiribati Ministry of Finance & Economic Development is to enhance sustainable economic growth and financial stability for the welfare of the people of Kiribati through promotion of appropriate economic and financial management methods and systems, computerized accounting and control systems, tax administration, customs enforcement, and provision of accurate and quality national statistical information.
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
This tool was developed by Liemberger and Associates under the auspices of the Water Loss Specialist Group of the International Water Association.
In 1998, Kuala Lumpur, capital of Malaysia, faced a water shortage. Water had been rationed for 5 months. To end this situation, the Ministry of State for Water Supply engaged an operator under a performance-based contract (PBC) with the aim of reducing non-revenue water (NRW).
