The EPA recently developed a mobile web app and website to help people find the condition of their local waterways using a smart phone, tablet, or computer.  The new app will allow people to easily access information about their local waters, pollution problems, why they matter, and whats being done to restore and protect them.  Click here to visit the EPA's "How's My Waterway" page.

Curbs and gutters are designed to transport rainwater to the Town's separate storm sewer system. Please place your trash, recycle carts, and yard debris on the curb on collection day. Containers that are placed on streets can be moved by high rains flowing into the storm sewer system, which can block stormwater inlets and even cause street flooding. Please make sure leaves, limbs, and other yard debris are not on the street either.  Leaves and debris can clog drains and pipes, which can also lead to flooding. Anything other than rainwater is prohibited to enter the storm sewers. The Town's loose leaf collection service runs from the first Monday in November until the last Friday in March. Pine needles will not be collected by loose leaf collection crews. Please bag all piles of pine needles and place them on the curb for collection on your regular garbage day. Loose leaf collection routes follow the regular solid waste collection schedule as closely as possible. For more information, please call (901) 457-2800.


Draining Your Swimming Pool

Did you know that your pool can be a water pollution source? You could be polluting the waters of Tennessee and Collierville by draining the water from your swimming pool to the street and down the storm drain. Water that is discharged into the street gutters and storm drains goes directly to lakes, ponds, streams, and rivers untreated. The chemicals in pool water are harmful to aquatic life and other wildlife. Pool water must be discharged into the sanitary sewer for treatment at the wastewater treatment plant before it is released back into the environment. Rain water from pool covers may be discharged into the yard (preferred) or to the street gutter. If you have questions about the Town's Stormwater Program, or need additional information, please contact Robbie Hanks at (901) 457-2346. Link to the Town of Collierville’s Stormwater Ordinance

Stormwater Runoff

Stormwater runoff is generated when precipitation from rain and snowmelt events 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. over land or impervious surfaces and does not percolate into the ground. As the runoff flows

The Town of Collierville is regulated by the State of Tennessee Department of Environment and Conservation (TDEC) through the National Pollutant Discharge Elimination 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.  To view a complete copy of the Town of Collierville's Stormwater Management Program see,  The Town of Collierville's Stormwater Management Handbook, and The Town of Collierville's Stormwater ordinance.


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.
