Water Quality Information
Mount Joy Township began implementing its Municipal Separate Storm Sewer System (MS4) water quality program in 2018. Our storm sewer system consists of the Township-owned roads, storm pipes, swales, inlets, and basins that collect and convey rainfall to waterways. All runoff that passes through the Township’s MS4 and exits through an outfall is the responsibility of the municipality. The Pennsylvania Department of Environmental Protection and U.S. Environmental Protection Agency administer the MS4 program and provide useful information on stormwater management via their websites. Read the Township’s MS4 compliance annual report here.
It takes a collective effort to improve the quality of the runoff that ends up in our local creeks and streams. Rain and snow that does not soak into the ground flows downhill until it reaches a waterway, taking with it any soil, debris, trash, or pollutants. Remember that the storm pipes and inlets along the roads ultimately flow to surface waters, so help make sure only stormwater flows to the storm sewers!
If you see anything other than stormwater flowing through the storm sewer system, contact Mount Joy Township at 717-367-8917 or email firstname.lastname@example.org to report it. Prevention is the best way to eliminate pollutants from our waterways, although accidents are bound to happen. Our Illicit Discharge Detection & Elimination (IDD&E) Program sets forth the Township’s protocols when pollution appears to be within the storm sewer system.
Collaborative Water Quality Improvements
We recognize that achieving our community’s water quality goals is much more efficient and effective when working together. Mount Joy Township is also proud of the Green Meadows Streambank Stabilization Project, which is possible due to the cooperation from the owners and management of the Green Meadows Mobile Home Park. The project will stabilize the Conoy Creek’s banks within the community, resulting in a sediment reduction of over 40% of the Township’s obligation.
Another great example is the Conewago Creek cooperative effort with Londonderry Township in Dauphin County. This multi-phase project has the potential to significantly improve the water quality and wildlife habitat for a large stretch of the creek.
