WSO, Inc. (a former subsidiary of Waterframe Limited, now an E-Source company) completed the GWA Water Loss Control Program Development and District Metered Area Implementation Plan in 2021. The program development works comprised three main phases:
The Water Loss Control Program recommended a 5-year Capex and Opex program to implement 36 DMAs covering the entire GWA water supply and distribution network, building water loss control capacity, and carrying out comprehensive leak detection and repair activities, all with them aim of reaching the economic level of losses over the 5-year program timeline.
In 2021, GWA embarked on delivery of the Water Loss Control Program with Waterframe providing Technical Assistance for program management, training and ongoing water loss assessment.
The DMA implementation also includes the provision of the NRWManager non-revenue water management system. This system allows the DMA inflow to be monitored and also the monthly NRW volume to be automatically calculated for each DMA.
