The City of Sunnyside Sewer Division is responsible for operating and maintaining the City sewer collection systems, lift stations, and the Wastewater Treatment Plant.

Wastewater Collection
Wastewater Collection provides for the collection and treatment of the communities wastewater. Any interruption of this service could result in a public health hazard and increased costs associated with regulatory fines and claims for damages.

Maintenance goals are generally based on cost effectively keeping the system operational. Cost-effective maintenance programs are those that stress preventative maintenance and initiate action before problems occur.
