Stormwater runoff is generated when precipitation from rain and snowmelt events flows over land or impervious surfaces and does not percolate into the ground. As the runoff flows over the land or impervious surfaces (paved streets, parking lots, and building rooftops), it accumulates debris, chemicals, sediment or other pollutants that can adversely affect water quality.
The Town of Collierville is regulated by the State of Tennessee Department of Environment and Conservation (TDEC) through the National Pollutant Discharge Ellimination System (NPDES) General Permit for Small Municipal Storm Sewer Systems (MS4s). This permit requires the municipality to develop, implement and enforce a Stormwater Management Program which consists of the following six minimum control measures:
A separate page has been assigned to each minimum control measure (located under the Stormwater Menu) to highlight program initiatives and upcoming events.

Quite often drainage issues arise in which no Town drainage structures or easements are involved. As subdivisions mature, it is important to keep in mind that, drainage patterns change. Over time, fences, swimming pools, flowerbeds and sheds are built. Trees, bushes and other vegetation get larger and larger. Without proper homeowner planning and maintenance, all of the above mentioned items can adversely effect storm water runoff, not only on the subject property but for that of the neighbors’ properties as well.
Property owners have the responsibility of allowing stormwater runoff to enter and exit his/her property without altering impacts upstream or downstream of his/her property. The southeastern United States uses the "Civil Law " to govern drainage disputes between property owners.
