Improvements to Swiftcurrent Sewage System and the Many Glacier Wastewater Treatment Plant

Glacier National Park is proposing improvements to the sewage system and wastewater treatment facilities in the Many Glacier Valley. Both the sewage and treatment systems are over 30 years old and are showing signs of deterioration. The park proposes to improve and rehabilitate parts of the sewage lines and treatment system to meet current permitting requirements of the Montana Department of Environmental Quality (MDEQ). The facility is operated from May to October and consists of headworks, an aerated lagoon, percolation ponds, and a control building. There are deficiencies with the aeration system within the lagoon and the original lagoon liner has been damaged several times. In addition, the lagoon's recirculation system is inoperable due to pump failure. Improvements and repairs are also proposed for the control building, the percolation ponds, and the surrounding fence. The existing sewer system collects waste from Swiftcurrent and Many Glacier. According to a recent engineering report, the lines from Swiftcurrent are narrow, have become temporarily blocked during operation, and do not meet MDEQ standards. Minor modifications to the Swiftcurrent lift station are also proposed to enhance safety and efficiency for operators.
