Stormwater Management

Protecting Our Water

Delhi Charter Township will be working with area agencies to help further protect our water resources as part of new Environmental Protection Agency storm water management rules. Future plans will include everything from possible ordinances to protect wetlands to public education about what you can do to protect our precious water resources.

Stormwater runoff is created when rain or melt water falls on pavement, buildings, and other impervious surfaces that do not allow water to soak into the ground.  In developed areas like some areas of Delhi Township, we limit flooding by moving this runoff from our roads, parking lots, and neighborhoods through storm drains which discharge directly into rivers and streams.  Because runoff water in our storm sewers does not get processed at a treatment plant, any contaminant on the ground can be carried with the runoff and impact our shared surface waters.  Pet waste, oil, leaves and dirty water from washing your car can enter storm drains.  This dirty water can flow downstream where it harms aquatic habitats and makes water unsafe for swimming, canoeing and other water related activities.  Delhi Township takes steps to reduce this pollution to improve water quality.

To meet State and Federal requirements, Delhi Township must apply for a Stormwater discharge permit every 5 years.  A large part of that application consists of a description as to how the Township will commit to and proceed with the development, implementation, and enforcement of practices to reduce the discharge of pollutants from its municipal separate storm sewer system (MS4) to the maximum extent practicable.  This documentation was formally designated as the Delhi Township Stormwater Management Program.  The program is available for public review by following the links below.  For input or to comment on the program, contact the Delhi Department of Public Services.

To help facilitate a regional approach to Stormwater management, Delhi Township is also a member of the Greater Lansing Regional Committee for Stormwater Management (GLRC), a guiding body comprised of Municipal Separate Storm Sewer System (MS4) communities within the Greater Lansing Region.  The Committee has been established to guide the implementation of the stormwater program for participating communities within the Grand River, the Red Cedar River and the Looking Glass River watersheds.  Visit to learn about upcoming events, find steps you can take to limit water pollution, and to get involved in managing our shared water resources.
