The Town has two wastewater treatment plants.
The central wastewater treatment plant is located East of Town on Highway 60. This plant was upgraded in 2004 to treat 750,000 gallons of wastewater per day using aerated lagoons and a Dissolved Air Flotation (DAF) system. When the plant was upgraded it was designed so the capacity can be increased to treat 1,500,000 gallons of wastewater per day.
The Low Point wastewater plant is located on Highplains Blvd. This plant was completed in 2005 to treat 500,000 gallons of wastewater per day using a Sequencing Batch Reactor (SBR) system. The plant can be upgraded to treat 1,000,000 gallons of wastewater per day.
