Water Demand Management

More Water from the System You Already Have.

From pinpointing invisible leaks to deploying smart metering across entire networks, we help municipalities and water authorities recover lost water, reduce operating costs, and extend the life of existing infrastructure.

Water lost before it reaches the tap?​

Across Southern Africa, demand consistently outpaces supply, yet a significant share of treated water never reaches a paying consumer. Closing that gap is an engineering problem with measurable solutions.

High Non-Revenue Water

South African municipalities lose an average of 37% of water to leaks, theft, and metering inaccuracie, water paid for but never billed.

Ageing Pipe Infrastructure

Decades-old distribution mains fail silently, with leaks migrating underground for months before causing visible damage or water loss alerts.

Uncontrolled Pressure

Excessive network pressure is the single largest driver of burst frequency and background leakage, yet most networks operate without active pressure regulation.

Limited Demand Visibility

Without granular consumption data, utilities cannot identify wasteful patterns, prioritise interventions, or make the case for capital investment.

End-to-end demand management capability

We combine field surveys, hydraulic analysis, and technology deployment to reduce water losses and improve system efficiency across the full demand chain.

Leak Detection

Systematic identification of real losses across distribution networks using acoustic correlators, step-testing, and district metered area (DMA) analysis. We locate leaks others miss.

Non-Revenue Water Reduction

Structured NRW programmes that quantify real and apparent losses, identify root causes, and deliver a prioritised reduction roadmap, aligned with DWS targets and WCWDM requirements.

Pressure Management

Hydraulic analysis and PRV design to bring network pressures within optimal operating bands, reducing burst frequency, background leakage, and energy consumption simultaneously.

Smart Metering

From technology selection to bulk AMR rollout and AMI integration, we guide utilities through the full smart meter deployment lifecycle, ensuring data flows into actionable operations dashboards from day one.

Consumer Water Efficiency

Re-Solve- infrastructure project

Demand-side programmes that translate metering data into behaviour change, from large-account audits and leak-on-property investigations to structured water efficiency campaigns for residential consumers.
