The Portage Lake Water & Sewage Authority
(PLWSA) was established in 1964...
by the cities of Hancock and Houghton for the purpose of constructing and operating a joint use wastewater treatment facility. The facilities that were constructed included a lift station for each city to convey wastewater to a common site and a wastewater treatment plant located on the south shore of Hancock.
Planning was initiated by the PLWSA in 1987 when it became evident that the existing treatment plant was operating at flows in excess of the design flow and was not able to treat all of the excess flow that was being generated by both cities.
