摘要

本文分析了采用需求和压力管理技术对供水管网成本的影响。该分析是基于使用不同压力等级的管道为4000户家庭提供一系列小时需求的成本。需求管理可降低25-45%的成本,压力管理可进一步提高20-55%的成本。对于每户每小时低于50升的需求,从网络基础设施到物业的成本转移,以支付储水和消防喷淋系统的成本。该分析强调了在供水基础设施中提供基于街道消火栓的消防的隐性成本。

Effect of demand management and system operation on potable water infrastructure costs

The effect of employing demand and pressure management techniques on the cost of water reticulation systems is analysed in this paper. The analysis is based on the cost of supplying a cluster of 4000 households serving a range of hourly demands using pipes of various pressure classes. Demand management reduces costs by 25–45% and pressure management increases savings by a further 20–55%. For demands below 50 l per household per hour there is a cost shift from reticulation infrastructure, to properties, to cover the costs of water storage and fire sprinkler systems. The analysis highlighted the hidden cost within water supply infrastructure to provide fire protection based on street hydrants.
