Guidance on evaluation and selection of sustainable water demand management technologies

Abstract

This report presents guidance for the evaluation and selection of Water Demand Management (WDM) type technologies for the effective and efficient reduction of water consumption for different water stakeholders - householders, Water Service Providers (WSPs) and policy makers - in a technically sound, yet economically, environmentally and socially acceptable way for all stakeholders involved. The technical guidance is based on reviews of different WDM technologies and methodologies developed in Work Package 42 of the TRUST project. The WDM interventions considered in the report have been evaluated largely based on the their overall water saving potential, cost-effectiveness, water-related energy use as well as impact on the reliability of supply/demand balance of Water Distribution Systems (WDSs).
