Public Works Department

The Public Works Department manages and maintains the City's garbage/recycling service, irrigation, parks/facilities, streets/trees (in the City's right-of-way), wastewater system, and domestic water supply.


The dedicated members of the Prosser Public Works Department maintain Prosser's most valuable assets. The Public Works Department treats and distributes water to over 2,000 domestic utility services in Prosser. The Public Works crew maintains the Prosser Irrigation Distribution System, working closely with Sunnyside Valley Irrigation District, to provide dependable and convenient service to our residents. The experienced and knowledgeable staff also maintain our roadways to keep them safe and welcoming to visitors.  The City's many beautiful park areas and fun playgrounds are maintained by the Public Works Department making all of these facilities one of the many jewels of our community.
