Water distribution systems traditionallyhave been designed and operated to consistentlysupply water of acceptable quality, insufficient quantity, at appropriate pressure, aseconomically as possible. Significant energy isused to move water from one location toanother via pumps, but some of that energy islost through pipe friction, across control valves,and at customer taps. As awareness of climatechange has increased, utilities are reevaluatingtheir system operation and design with theobjective of minimizing environmental impacts.To achieve this goal requires an accurate assessmentof current energy use in order to recognizepotential sources of energy savings andeffectively manage carbon emissions associatedwith water supply and distribution.This article introduces a powerful approachto help water providers perform an energy auditof their distribution system. By optimizingsystem performance for maximum energy costsavings while preserving system hydraulic integrityand reliability, utilities can reduce bothoperating costs and their carbon footprint.
