Overview of the System

The City of Prosser is supplied water from five primary source wells and one emergency well.  However, one source well (Well #2) is not currently operable due to sand production. The maximum pumping capacity of the five primary wells is currently 6,040 gallons per minute (GPM) or 8.7 million gallons per day, although normal production is limited to 3,850 GPM or 6.29 million gallons per day due to water right restrictions.  All five wells pump water directly to the City's 7.78 MG water treatment plant. Three reservoirs serve the City with a combined capacity of 5.45 million gallons. The existing transmission and distribution system is looped in most areas and generally consists of 6-inch or larger water mains. The City has approximately 41 miles of domestic water piping.
