Stormwater Stormwater runoff is commonly transported through Municipal Separate Storm Sewer Systems (MS4), from which it is often discharged untreated into local water-bodies. To prevent harmful pollutants from being washed or dumped into MS4, the City of Lancaster must obtain NPDES permit and develop a stormwater management program.
The City of Lancaster administers Stormwater Management Program (SWMP) in compliance with the Texas Pollutant Discharge Elimination System (TPDES) general permit. The City is actively participating in the Municipal Separate Storm Sewer Systems (MS4) program, phase II. The City of Lancaster's SWMP includes best management practices developed for each of the following 5 minimum control measure:
