Tri-Lakes WWTF Combines Biolac® Long Sludge Age Treatment System With MRI Plate Settlers To Achieve Low Nutrient Limits

The Tri-Lakes Wastewater Treatment Facility located in Monument, CO, receives flow from the Woodmoor, Palmer Lake, and Monument Sanitation Districts. The plant discharges treated effluent to Monument Creek, which is within the Fountain Creek Water Shed. Originally, the Tri-Lakes facility consisted of a three-cell lagoon. This was replaced by a two-basin Biolac® Wave-Ox™ system, which was installed in 1990 and later upgraded in 1998 to a three-basin system with a capacity of 4.2 MGD.
