From Septic Struggles to Clean Water Triumph: Worth Township’s Lake Huron Revival

Sanilac County

The Story

A three-mile stretch along Lake Huron in Sanilac County, MI became severely compromised by sewage contamination as years of failing septic systems allowed untreated wastewater to infiltrate surface waters, threatening both the environment and public health. In 2003, the Michigan Department of Environmental Quality (now EGLE) identified this area as a critical environmental hazard and placed it on the state’s list of impaired water bodies. Testing revealed dangerously high levels of fecal coliform and E. coli, prompting EGLE to issue an urgent directive: Worth Township was required to develop a comprehensive wastewater collection and treatment system to protect public health and restore water quality.

After years of legal disputes and planning delays, the project finally advanced in 2012 with support from the Rural Community Assistance Partnership (RCAP). The team faced numerous challenges, including deep ravines, incomplete infrastructure records, and complex financing requirements. By refining the original design—reducing the number of pump stations from 14 to eight and opting for a lagoon treatment facility—they significantly lowered costs while meeting strict environmental standards. Completed in 2019, the system now provides residents with modern, reliable sewer infrastructure.

This initiative not only resolved critical environmental issues but also set a new benchmark for municipal efforts to protect Michigan’s Great Lakes Basin. Worth Township has secured the long-term health of its community and preserved the environmental integrity of the Lake Huron shoreline.
