WSUP’s approach

WSUP supports water operators and utilities to reduce water loss by mainstreaming NRW procedures within their operations. Fundamental to this is developing capacity and skills together with necessary institutional restructuring to operationalise NRW technologies and procedures including leakage management.

Reducing water losses has an impact across the city, as it enables improved services to existing customers, extension of services to un-served areas and enhanced utility investments in service improvements due to increased revenues.

WSUP’s experience shows that utilities should first invest in water loss reduction prior to making significant capital investments in increasing water capacity.

Supporting JIRAMA in Madagascar

WSUP’s support  to Madagascar’s national utility JIRAMA in the capital Antananarivo (Tana) since 2010 with its NRW is a good demonstration of the power of NRW reduction programmes to improve both commercial viability for the utility and outcomes for the consumer.

Significant reductions in water losses have been achieved in Tana with relatively low levels of investment, resulting in increased revenue for JIRAMA, better services for its customers and the extension of services to under-served areas.

JIRAMA’s water losses of 19-20 million m3 per year were significantly reduced by the NRW programme and WSUP estimates that 710,000 low income customers in Tana have benefitted due to the savings.

NRW reduction in low-income areas of Mombasa, Kenya

In Kenya, WSUP has supported the Mombasa Water Supply and Sanitation Company (MOWASSCO) since 2013. One of the support areas involves non-revenue water reduction in the low income areas: working with MOWASSCO, the local administration and consumers to identify illegal connections.

The connections are then dismantled, which resulting in more water availability for legal metered customers. In time, the households who had illegally connected to the network apply to utility for a legal connection – resulting in more customers for the utility, contributing to increased revenues for MOWASSCO.

Our work in Mombasa has shown how NRW reduction can be more effective by increasing awareness in the community of the importance of tackling illegal connections.

A guide to non-revenue water reduction: how to limit losses, strengthen commercial viability and improve services

In 2017 WSUP published a guide as a resource for water utilities to support implementation of Non-Revenue Water (NRW) reduction programmes.

It covers what NRW is and why it matters, before providing systemic guidelines that can be adopted by utility managers, engineers and operations staff to plan and implement a phased, sustainable NRW programme.
