In 1945, the first steps were taken to provide for the treatment of the City of Billings wastewater. Subsequently, a 15 million gallon per day (MGD) treatment plant was constructed, and was placed in service in 1950. In the early 1970s, the treatment plant was enlarged to provide both primary and secondary treatment for an average wastewater flow of 26 MGD and a maximum flow of 40 MGD.
