Streets & Drainage

About the System

The storm water system commonly referred to as the drainage system is operated and maintained by the Operations Division of Public Works.

Access more information on the current City-Wide Drainage Study.


Storm water run-off (storm sewer) is collected in the curb and gutter streets and channeled to the underground piping network which conveys the water to larger stormwater structures and ditches. It then flows into Braes Bayou and then flows to the San Jacinto River Basin - Houston Ship Channel Segment 1007 and finally to Galveston Bay and the Gulf of Mexico.


The division is concerned with the transportation of the water away from the city as well as with the prevention of pollution of the water bodies into which the system discharges. The Texas Commission on Environmental Quality (TCEQ) regulates the discharge of pollutants into and from storm sewer systems. The city has prepared a Storm Water Management Plan (SWMP) (PDF) to guide us in meeting the storm water discharge permit from the TCEQ. View the Storm Water Discharge Permit (PDF).
