Storm Water Management & Pollution Prevention

Inflow/Infiltration (I/I) Reduction Program – Sanitary Sewer Smoke Testing 

The City of Rosenberg Utility Department is in the process of implementing an Inflow/Infiltration (I/I) Reduction Program and will begin sanitary smoke testing within the city. The program objective is to remove storm water sources from the sanitary sewer system, keep wastewater treatment costs and sanitary sewer rates low, and protect the environment.

Smoke Testing is a standard method of detecting sewer defects and storm water cross connections to the sanitary sewer system. Smoke testing consists of placing a high capacity blower on top of a sanitary sewer manhole and forcing “smoke” down into the sewer system. The smoke, under pressure from the blower, travels through the sewer system and escapes through any connection, cracks, leaks, etc., along the way. This quickly reveals sources of I/I within the study area.

Storm Water Pollution Prevention… only rain goes down the drain!

As storm water flows over driveways, lawns, and sidewalks, it picks up debris, chemicals, dirt, and other pollutants. Storm water can flow into a storm sewer system or directly to a storm sewer, ditch, stream, river, or other bodies of water. Anything that enters a storm sewer system is discharged untreated into the bodies of water we use for swimming, fishing, and providing drinking water. Polluted runoff is the nation’s greatest threat to clean water.

By practicing healthy household habits, homeowners can keep common pollutants like pesticides, pet waste, grass clippings, and automotive fluids off the ground and out of storm water.

Adopt the tips in the Healthy Household Habits for Clean Water [PDF] and Preventing Storm Water Pollution [PDF] brochures and help protect streams, rivers, wetlands, and coastal waters.

The City has established a REPORTING HOTLINE for alleged violations – (832) 595-3301.

Storm Water Management Plan

The City was issued a permit under the Texas Pollutant Discharge Elimination System (TPDES) General Permit TXR040000 for discharge of storm water to Small Municipal Separate Storm Sewer System (MS4). The City completed a five (5) year program under this permit to implement a required Storm Water Management Program. The City’s application for a new permit is under review with the TCEQ. A copy of the City’s Storm Water Management Plan [PDF] submitted with the permit application is available here.
