GLUA Sewer Information

The draft Higgins Lake sewer feasibility study, also called a Preliminary Engineering Report (PER) was submitted to the United States Department of Agriculture Rural Development (USDA-RD).  The feasibility study was funded by a $30,000 grant from the USDA.

Representatives from Gerrish and Lyon Townships met with engineers on February 14, 2020 to discuss the project. As was presented at the October 2019 informational meeting, based on science and studies going back more than 50 years, there have been demonstrated negative impacts to the environment and the lake quality. The team feels it is important to continue investigating opportunities to protect Higgins Lake by installing public sewers.

The Townships are currently looking at the qualifications and experience of municipal financial advisors and bond counsel who can provide valuable information into project costs and financing options. We plan to have a team identified and engaged soon.

Additional work will take place as the team continues to gather information and inform the public about the project. Cost is a big question/concern for Townships and residents, and we will meet with agencies to discuss potential funding opportunities over the next couple of months.
