Spanish Fork Wastewater Division
About the Sewer Treatment Plant
The Spanish Fork Sewer Treatment Plant processes an average of 4 million gallons of sewage per day for Spanish Fork and Mapleton Cities.
The treatment plant was first built in the 1950s with major upgrades in the 1980s. The plant uses a biological process to clean water meeting Utah State and EPA regulations. After treatment, the waster is disinfected using chlorine and discharged to Dry Creek which ultimately flows to Utah Lake.
Biosolids that are removed from the sewage are processed using anaerobic digestion meeting Class B biosolid regulations. Once processed and tested they are safely used as a fertilizer for agriculture purposes.
Due to ageing infrastructure, state regulation, and population growth, a new modern treatment plant is under construction to replace the existing plant. The new treatment plant will be capable of processing 8 million gallons per day and will meet state-mandated nutrient removal requirements. Construction for the new facility began in 2022 and will be completed in early 2025.
About the Sewer Collection System
Spanish Fork City's Wastewater (Sewer) Division manages the city’s wastewater collection system, which consists of an estimated 167 miles (880,000 ft) of sewer pipe throughout the city.
In order to properly maintain high-quality sanitation standards, as well as to prevent back-ups and other problems, the Division has a goal to clean approximately one-quarter of the sewer lines in town each year, while cleaning progress is tracked and reported quarterly.
The Wastewater Division uses video equipment to inspect wastewater pipes. Video inspection is used at the time of construction and every 7 years following construction. The Division also visually inspects each manhole every 4 years. Inspection of sewer pipes and manholes helps prevent problems in the lines.
For more information, see the Sewer Management Plan.
Utah County City Bill Comparison
Spanish Fork City has one of the lowest sewer rates in the area. This is primarily due to four factors:
- We are proactive in replacing sections of the sewer main line;
- We repair and replace before system failures occur;
- We are mostly a gravity flow system (reducing the need for pumping); and
- We have one of the smallest sewer department crews in the state.
