The Town of Harrisburg's Stormwater Ordinance went into effect January 1, 2008. Stormwater Management staff protects the health and safety of the public by addressing stormwater quality and quantity concerns and ensuring compliance with federal and state stormwater mandates.
Source of Pollution
There are many sources of stormwater pollution, including:
- Automotive fluids
- Brake dust
- Cigarette butts
- Grass clippings
- Pet waste
When it rains, these pollutants can be carried into the nearest storm drain or drainage ditch alongside the street. The storm drainage system is separate from the sewer system. The sanitary sewer system carries water to a wastewater treatment plant where it is treated before it is released. Stormwater runoff is not treated by a wastewater treatment plant.
Stormwater, and everything it carries with it, drains to a creek or river, without ever being treated. Impervious surfaces, which are hard surfaces that don't allow rain to absorb into the ground (such as rooftops and pavement), cause runoff water to drain more quickly off the land instead of soaking into the ground.
Areas covered with grass, trees, gardens and gravel are not considered impervious areas. The stormwater fee is based on a property's impervious surface area. The more impervious surfaces, the more stormwater runoff flows from the property into the stormwater drainage system. Homes with the least amount of impervious area pay the lowest stormwater fee.
