Secondary water systems deliver water that is oflower quality than drinking water, usually to supplyoutdoor irrigation needs. Secondary water sourcesinclude untreated mountain runoff and groundwaterthat is unsuitable for drinking. An increasing numberof secondary systems are considering meteringthis water to encourage user conservation, becausethe lack of metering on these systems has beenshown to lead to an increase in overall water use.This study compares different metering technologies,some of which require filtration to cleansecondary water to a level sufficient for meters toperform well. The authors describe the costs,benefits, and disadvantages of various strategiesfor metering and associated filtration as well asthe option of not metering. The article providesan approach to estimating the initial costs ofmetering per connection. Practices of secondarysystems in Utah are discussed to provide perspectivein making the decision of whether or not tometer, which usually focuses on economicfeasibility. Includes 24 references, tables, figure.
