Stormwater Management

The Public Works Division leads the City’s efforts to protect water quality and the health and safety of both the public and the ecosystem by reducing the discharge of pollutants into the storm drain system to the Maximum Extent Practicable (MEP). The stormwater system is not a part of the sewer system.

Stormwater management is the effort to analyze, understand, and address stormwater runoff from a water quantity and water quality perspective and for addressing stormwater runoff for the purposes of: 

  • Reducing downstream erosion 
  • Water quality monitoring and public education
  • Flooding management and drainage maintenance
  • Mitigating adverse effects of changes in land use and runoff characteristics on the aquatic environment

Regulatory Compliance

The Texas Commission on Environmental Quality (TCEQ) has renewed the "stormwater" General Permit for Small MS4s.
On January 16, 2019 the Commission adopted the 2019 TPDES general permit for small MS4s, TXR040000.  The general permit’s effective date is January 24, 2019.  Starting from the effective date of the general permit, permittees have 180 days to submit a Notice of Intent (NOI) with an updated Stormwater Management Program (SWMP).

To comply with State TCEQ Phase II MS4s general permit and Federal EPA regulations for protecting stormwater quality, since 2007, the City of Sachse is required to implement a Stormwater Management Plan (2019 SWMP) as a level 2 operator. The SWMP describes certain Best Management Practices (BMPs) the City will implement in order to comply with the Minimum Control Measures (MCMs) set up for Phase II permitees. The MCMs required by the Phase II Rule include:

  • Public Education, Outreach, and Involvement 
  • Illicit Discharge Detection and Elimination (IDDE) 
  • Construction Site Stormwater Runoff Control 
  • Post-construction Stormwater Management 
  • Pollution Prevention and Good Housekeeping for Municipal Operations

This program provides support for compliance with the Construction General Permit (CGP) and the Small Municipal Separate Storm Sewer System (MS4s Permit). The City of Sachse also participates in the NCTCOG regional stormwater management program providing public education and outreach, and training.

Stormwater Pollution Prevention

The best way to protect storm water runoff quality is to avoid polluting in the first place.

  • Recycle  or properly dispose of household products that contain chemicals, such as insecticides, pesticides, paint, solvents, used motor oil, and other auto fluids. Don’t dump them onto the ground or into storm drains
  • Dispose of household hazardous waste properly. The City of Sachse participates in the Dallas County Household Hazardous Waste Disposal Program
  • Do not blow grass clippings into storm drains or the streets
  • Develop and implement a Storm Water Pollution Prevention Plan (SWPPP)
  • Prevent stormwater pollution at construction sites

Types of Illegal Discharges                                     

  • Dumping of yard and pet waste                                 
  • Dumping of fats, oils, and grease                                     
  • Roadway accident spills                                      
  • Sanitary wastewater and direct septic connections                                      
  • Industrial and commercial connections                                      
  • Sediment and erosion from construction sites                                     
  • Blowing grass clippings into a storm drain
