Stormwater runoff is generated when precipitation from rain and snow flow over land and impervious surfaces and does not infiltrate into the ground. The runoff from streets, lawns, farms, and construction and industrial sites pick up fertilizers, dirt, pesticides, oil, grease and many other pollutants and discharge into our lakes, streams and rivers. This untreated discharge is detrimental to our water quality as it can adversely affect our drinking water supply and environment. Many detention/retention/infiltration basins are already in place to help keep our water clean.

Stormwater Management, Simplified.
Have you ever wondered where all that water that gushes into a storm drain ends up? The journey does not end there... This story map provides a summary of the stormwater journey, including what stormwater contains, how it is managed, and its impacts on New Hanover Township streams and the community.

Stormwater from my neighbor's property is causing erosion and flooding problems on my property. What can I do?
A landowner has the right to have stormwater flow onto and over his property, and discharged through a natural water course onto a neighboring property. In addition, a landowner may make proper and profitable use of his land even though this use may result in some change in the quality or quantity of the water flowing to the property below.
Generally, any damage to the property below caused by surface water as a result of this use is not actionable. However, there are two exceptions to this general rule. The first exception is when the stormwater is diverted from its natural channel, and the second exception is when stormwater is unreasonably or unnecessarily changed in quantity or quality.
If you believe that either or both of the above-noted exceptions are applicable to your case, you should contact an attorney with experience in these matters. For if your neighbor is not willing to fix the problem you may be required to file suit in the Court of Common Pleas. Because the stormwater is flowing from private property, the Township is not a party to such disputes.

The Township regulates its stormwater management through a permit that is obtained from the Pennsylvania Department of Environmental Protection (PA DEP) through the National Pollution and Discharge Elimination System Phase II (NPDES)/Municipal Separate Storm Sewer System (MS4). This is a federal requirement from the United States Environmental Protection Agency (USEPA) that is administered by the state. This NPDES permit is broken up into six minimum control measures to be regulated and enforced by the Township. These minimum control measures include:
- Public Education and Outreach
- Public Participation/Involvement
- Illicit Discharge, Detection and Elimination
- Construction Site Runoff Control
- Post-Construction Runoff Control
- Pollution Prevention/Good Housekeeping
For any questions or concerns regarding stormwater or to report illicit discharges to the storm sewer system, contact the Township at 610 323-1008.
There are many ways you can help the Township with its stormwater program, such as participating in volunteer programs that help keep trash, debris and other pollutants out of the storm sewer system. For more information on ways to get involved with your community, visit:
