Water Loss Reduction

An Innovative Solution for the Reduction of Apparent Losses

Under-registration of low flow rates is the main reason for apparent water losses. The UFR is an innovative product that reduces apparent water losses by changing the flow regime of low flow rates through the water meter. The UFR has been successfully tested and inspected worldwide.

Apparent Water Loss Control: The Way Forward

Water losses are grouped into two types of loss; Real losses, which are the physical losses (or leakage) andApparent losses, which are caused by revenue meter under-registration, water theft and billing errors.
WhilstReal losses are an expense due to lost water, Apparent losses are not so much an expense to the water utility asthey are a loss of potential revenue.

Investigations Into Under-Registration of Customer Meters in Palermo (Italy) and the Effect of Introducing Unmeasured Flow Reducers

Water supply system management has to be based on a deep knowledge of its cost, of the network water and energy consumption and of the level of water losses.
Every leakage control program has a water system balance as a common starting point (Ismail and Puad, 2006).
