Non-Revenue Water prevention

Technimex introduces Non-Revenue Water (leakage) prevention by intelligent water management. We refer to it as non-revenue water (NRW), or water that is pumped and then lost or unaccounted for.

Non-revenue water (NRW) management allows utilities to expand and improve service, enhance financial performance, make cities more attractive, increase climate resilience and reduce energy consumption

By managing water pressure as an intermediate solution we are able to get instant results without replacing pipes.

Water loss reduction

The pressure level in the network has to be kept and controlled on a minimum level, which is necessary to maintain the actual water demand. Too low pressure can cause pipe vacuum, as booster pumps of high rises suck too much water from the pipeline that causes ground water to leak into the pipeline.

Reducing pipe bursts

With the variations in the demand of water during the day, week, month and year, the pressure in the water networks varies accordingly, with a wide amplitude.

The amplitude of the pressure variation should be kept as small as possible to prevent the network from being damage. Pipes always break at night when demand is low and pressure is relatively high.


Technimex delivers an almost ‘plug-&-play’ container or manhole which will be installed at the input-side of the critical area. This container or manhole includes the plunger valve which is used to control the pressure: 1% reduction in water pressure results in approximately 1.2% reduction of lost water. It also includes the actuators, and pressure- and flow sensors that are needed for the water management system. Additionally, to power the actuators and control system, a hydro-generator with battery backup is installed.
