Stormwater Management Program
Stormwater is any precipitation from a storm event (rain, snow, sleet, etc). Stormwater runoff is any precipitation that does not soak into the ground but instead runs off its surface. Non-porous or impervious surfaces such as driveways, sidewalks, and streets block precipitation from soaking naturally into the ground. Stormwater can carry and deposit chemicals and other harmful substances into surface-water bodies.
Because stormwater runoff from urbanized and developed areas can contain harmful pollutants, 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. 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.
