Municipal Separate Storm Sewer System

Municipal Separate Storm Sewer System (MS4)

Polluted storm water runoff from urbanized areas is a major source of impairment to water quality in Creeks, Rivers, and Lakes. The City of Bee Cave recognizes the importance of protecting our natural resources and environment. The city has developed a 'Storm Water Management Program' (SWMP) outlining the measures it will develop and specific actions that the city will implement over the next five years to reduce pollution in storm water to the maximum extent practicable. The program documents 22 best management practices (BMPs) as part of minimum control measures to meet the small City MS4 permit requirements of the Texas Commission on Environmental Quality (TCEQ). These steps include: methods to detect and eliminate illicit discharges to the storm sewer system, modifying municipal operations to limit discharge of pollutants to the waterways, enforcement to restrict construction and post-construction site erosion and eventual sedimentation and increasing public awareness regarding water quality protection.


Spilling, dumping, or discharging chemicals, hazardous materials, dirt, debris, sediments, oil or unknown substance into ditches, creeks, rivers, curb drains, storm sewer, inlets, and manholes is a violation of federal, state, and local regulations. Allowing sediment or chemicals to wash off a construction site is also a violation.

If you see someone is doing any such act, please report such bad practices to City of Bee Cave Planning and Development Department at 512-767-6675 or send an e-mail to [email protected].
