About Storm Water Services

​​​​​​​​​Established in the early 1990’s, Charlotte-Mecklenburg Storm Water Services is a joint municipal/county stormwater utility that includes Charlotte, the surrounding towns of Davidson, Cornelius, Huntersville, Matthews, Mint Hill and Pineville, and Mecklenburg County.

What We Do  

Storm Water Services works year-round to manage the runoff from rainfall, reduce flooding, restore floodplains and protect the water quality of surface waters county-wide. We accomplish this by:       

  • Increasing drainage capacity to meet growth and development demands

  • Repairing and replacing aging storm drainage infrastructure

  • Restoring severely eroded streams and floodplains to hold excess rain

  • Mapping floodplains to protect drainage capacity and manage floodplain development

  • Responding to residents who call 3-1-1 to report drainage and flooding problems

  • Monitoring surface waters for evidence of pollutants

  • Enforcing ordinances to protect surface waters

  • Educating residents about flood safety, pollution prevention and volunteer opportunities

Organization

Awards & Accomplishments

We are honored to have received awards in recognition of our efforts:

  • Charlotte Storm Water Services Granted Regional General Permit (RGP) 

    Charlotte Storm Water Services has achieved an unprecedented designation among municipal organizations in the Carolinas that will save time, money and headaches. On April 24, the U.S. Army Corps of Engineers (USACE) and NC Department of Environmental Quality (NCDEQ) issued a regional general permit (RGP) to Charlotte Storm Water Services (CSWS).  The federal Clean Water Act requires that impacts to streams, wetlands and ponds are approved by the USACE and NCDEQ.  Typically, projects that affect these waters require submittal of a Nationwide Permit application, with a 45-to-60 day review by these agencies. 

    The RGP is a 5-year programmatic permit that covers the vast majority of CSWS’s activities and eliminates the need for formal federal and state agency approval for many projects.  This is the first and, to date, only programmatic RGP issued to a municipal organization in the Carolinas.  That the RGP was issued solely to CSWS is a testament to the group’s quality of work.  RGP will benefit Charlotte residents because it (A) saves time, (B) cuts costs, (C) reduces uncertainty through the project approval process, and (D) provides CSWS with more flex​ibility in project design and implementation. ​More information on the RGP can be found below:
