Prior to this project, the City of Montrose owned and operated three sanitary sewer lift stations west of South Townsend Avenue. These lift stations were installed to support individual developments and were intended to be temporary in nature until a time when a gravity trunk line could be installed running north along the Uncompahgre River. All three of these lift stations were near the end of their service lives and were causing excessive corrosion of the sanitary sewer system downstream of their discharge points (due to hydrogen sulfide generated from the lift stations), and presented a large maintenance and environmental liability for the city.
The lift station elimination project installed a trunk sewer line along the future alignment of Rio-Grande Avenue as shown, eliminated all three of these lift stations, and placed this area onto the gravity sewer network.
