Non-Revenue Water in South Africa
Non-Revenue Water (NRW) is the difference between the volume of water entering a distribution system and the volume billed to consumers. Leaks, illegal or unmetered connections and inaccurate metering can reduce utility revenue, increase operating costs and contribute to unreliable supply. JOAT assists utilities to identify, quantify and reduce these losses through strategic planning, pressure management, leak detection, metering and network optimisation.
From Strategic Planning to Turnkey Delivery
JOAT provides the full spectrum of water systems optimisation: strategic planning, design, field implementation, commissioning, monitoring and handover. All required expertise in house.
