Description
This paper provides a comparison between the anticipated water quality (chlorineresidual) in remote portions of water distribution systems and/or dead-end lines forconventional flushing versus Advanced Maintenance Flushing. It has been demonstrated,using a computer model that more frequent, smaller volume, periodic flushing events willprovide for a consistent higher quality water in dead-end areas of distribution systemsthan is the case for less frequent, larger volume flushing events that take place betweenhigher velocity flushing or water main cleaning events. Programmable devices, asmanufactured by Hydro-Guard, allows implementation of the Advanced MaintenanceFlushing scenarios identified in this paper, where otherwise it would be impractical froma manpower standpoint to implement this flushing strategy on a manual basis. A seriesof case studies identify that the benefits of Advanced Maintenance Flushing that wereanticipated by water quality/hydraulic modeling are being accomplished throughout theUnited States. Currently hundreds of water systems are utilizing thousands of automaticflushing devices while implementing Advanced Maintenance Flushing. It is anticipatedthat as more water systems install automatic flushing devices and implement AdvancedMaintenance Flushing that more will be learned about the benefits of this type ofprogram along with information generated as to how to optimize both the design andoperation of this type of program. Includes 10 references, tables, figures.
