NRW Management Project Saves over 200,000 Cubic Meters of Water Yearly
Rustenburg, South Africa


The Rustenburg Local Municipality supplies water to approximately 500,000 people. Over the past two decades, the municipality has experienced tremendous growth, yet has not focused on water demand management. Non-revenue water (NRW) was about 40%, mainly due to poor metering and billing.


Project Goal

The project objectives were to reduce water leakage and increase revenue water follow through improved metering.


Project Scope

The progect began with the preparation of a comprehensive NRW strategy. Major target issues were identified, including sectorization, pressure management and leak detection. The study also found that commercial metering was low quality and many meters needed to be installed or replaced.


NRW reduction activities included:


  • Non-domestic meter upgrades
  • Installation of bulk management meters on all reservoir outlets
  • Leak detection and repair
  • Sectorization


  • Secorization, pressure management and leak detection and repair saved 201,480m3/yr in Lethabong county
  • Pressure management in Boitekong county saved approximately 151,548m3/yr
  • Water metering upgrades increased utility revenues and decreased NRW
  • Intermittent water supply eliminated - continuous water flow reduces the risk of waterborne diseases (typhoid, cholera, etc)
  • Less running water in the streets
