The Demand Management business area provides WRc's capabilities in the area of water demand

solutions to water companies, government, management includes all aspects of: demand analysis,

regulators and the supply chain to manage the domestic water use analysis, water demand forecasting,

balance between the supply and the demand for water. water balance calculations, leakage management,

leakage strategy development, water efficiency, water

conservation, network metering, tariff studies, water

charging and affordability, domestic metering and

research services.

We also provide pipeline inspection services using ®Sahara Pipeline Inspection, which provides network

operators with precise information on leak location, pipe

condition and mains location.

WRc provides a range of services in the following areas:
