Houghton, MI 49931

Established in 1964 by the cities of Hancock and Houghton, the Portage Lake Water & Sewage Authority (PLWSA) operates a joint-use wastewater treatment facility. Over the last decade, the PLWSA has significantly reduced energy consumption at the treatment plant, showing a commendable 33% decrease since 2012.

Annually, the PLWSA treats around 650,000 gallons of septage, including waste from septic tanks, port-a-potties, vaults, and grease traps. This vital service contributes to the national effort, as wastewater treatment facilities across the United States process a staggering 34 billion gallons of wastewater daily.
