Water distribution networks

Leakage

Efficient and cost-effective management of distribution systems requires the control of distribution system leakage.

Halcrow has experience in assisting clients in reducing leakage.

water leakage

Leakage from water mains is related to pressure and controlled pressure reduction can be a cost-effective way of reducing waste.

Halcrow has advised on the establishment of pressure reduction within operating distribution systems.

Studies have shown that timed pressure control during non peak periods can further reduce legitimate demand without inconveniencing customers.
