Wastewater Treatment

The City of Fruita operates and maintains a 2.3 million gallon a day, state of the art Biological Nutrient Removal (BNR) Wastewater Facility located just off 15 Road in Fruita. This facility currently treats just under 1.0 million gallons per day and is designed to accommodate the wastewater needs of the community for years to come.

The BNR Facility provides treatment of Carbon Oxidation (Biochemical Oxygen Demand, BOD) and Total Nitrogen (TN).  All current and future levels of BOD and TN proposed by the Colorado Department of Public Health and Environment can be attained. New effluent limitations based on anti-degradation evaluations will be determined each permit cycle (every five years).  To date, there have been no violations of the current permit. 

Beginning in 2027, new regulations requiring removal of total phosphorus to one mg/l will be a challenge for the existing wastewater plant. Phosphorus is a difficult nutrient to remove from the wastewater stream and requires sophisticated treatment processes. Facility planning will be needed to determine the best path to follow. 

Auto Thermophilic Aerobic Digestion (ATAD) was selected for the biosolids digestion process.  This system delivers superior volatile solids reduction and a pathogen reduction to low levels that meet EPA’s Class A certification. This classification allows for unrestricted use for land application (agriculture) or for lawns and flower beds. As a rate payer in the City of Fruita, the biosolids are offered at no charge.  Just make arrangements by calling 858-4081.
