Sewer System
The City of Mabton owns and operates a Waste Water Treatment Facility (WWTF) that is discharged into the Yakima River.

The WWTF improvements consisted of the construction of new headworks, aeration basin, secondary clarifier, effluent aeration manhole, electrical building, plant drain lift stations, non potable water system and sludge drying beds. Improvements also included modifications to existing operations building, oxidation ditch, sludge drying beds, secondary clarifier, effluent lift station and aerobic digester. The City is currently seeking a planning only grant to video tape the entire sewer system and start replacement of sewer mains.
