Stormwater Management Program

The City of Tomball is required under the Federal Clean Water Act and the Texas Water Code to obtain a permit to discharge stormwater runoff to waters in the State of Texas, because stormwater runoff from urbanized and developed areas can contain harmful pollutants. The permit requires the City to develop and implement a Stormwater Management Program (SWMP) and to take actions to reduce the discharge of pollutants in stormwater runoff to the maximum extent practicable.

Everyone in the City has a role to play in helping to reduce pollutants in stormwater runoff.
