SETTING A TARGET SAME: Production Consumption Network length No. Service connections Length service connections Average pressure SAME: Target Level ? X X X % l/con/hr ILI DIFFERENCE: C osts Economic problem having a technical solution

TECHNICAL SOLUTION Single inlet sectors Hydraulic model Pressure management Leakage detection and repair

WATER LOSS Economic and not technical parameter Varies from network to network Leakage too high – excessive operational costs Leakage too low – excessive intervention costs Has a direct impact on the customer - tariff

OPTIMUM LEAKAGE LEVEL Replace network Current production Consumption Total Exports Production Intervention TARGET LEAKAGE Repair leaks Pressure Control DMAs Requirement – system to generate the unique network curves

COMPONENTS INCLUDED Typical accuracy of network data Efficiency of pumps and their combination Commercial losses Impact of pressure management on leakage and maintenance costs Cost / benefit of leakage detection and repair Resource availability and intermittent supply

PALM+ control Dynamic control to maintain efficient operation PALM+ scada

CONCLUSIONS Water loss is primarily an economic and not a technical issue PALM+ defines the target operating level for any network – also over extended time period PALM+ derives the future consumption and balances water loss reduction against new production facility PALM+ assesses the impact any investment will have on the tariff to ensure a viable solution before any detail design has even started. PALM+ can maintain the efficient operation of a network in the future despite the dynamism.
