Storm Water Management Program

The City of Missouri City has developed a coalition with 16 surrounding Municipal Utility Districts, Utility Districts, and Water Control and Improvement Districts to create a joint Municipal Separate Storm Sewer System (MS4) program for the City of Missouri City Service Area. This program addresses storm water quality management issues typical of a growing residential community.

Municipal Separate Storm Sewer System

The City of Missouri City’s Municipal Separate Storm Sewer System (MS4) is a program that addresses the conveyance or system of conveyances that is owned and operated by a governmental entity and used for collecting or conveying storm water. The City of Missouri City created a Storm Water Management Program (SWMP) to manage the quality of discharges from the MS4. The SWMP includes best management practices and schedules for implementation to address 5 Minimal Control Measures (MCMs).

  • Public Education and Outreach on Storm Water Quality Issues
  • Illicit Discharge Detection and Elimination
  • Construction Site Storm Water Runoff Control
  • Post-Construction Storm Water Management in Areas of New Development and Redevelopment
  • Pollution Prevention/Good Housekeeping Measures for Municipal Operations

Preventing Contamination

Contamination of community drinking water threatens public health and causes significant cleanup expense. By preventing contamination of drinking water we avoid:

  • Cost of additional treatment facilities
  • Locating new drinking water sources
  • Re-establish citizens’ confidence in their drinking water, public utilities, and community leaders

Chemicals & Pet Waste 

Household Chemicals

Don’t pour chemicals onto the ground or into storm drains. View the storm water runoff diagram for how chemicals effect the water supply if disposed of improperly. Recycle or properly dispose of household products that contain chemicals such as:

  • Insecticides
  • Paint
  • Pesticides
  • Solvents
  • Used motor oil and other auto fluids

Pet Waste 

  • Flushing pet waste is the best disposal method.
  • Pet waste can be a major source of bacteria and excess nutrients in local waters.
  • When walking your pet, remember to pick up the waste and dispose of it properly. Leaving pet waste on the ground increases public health risks by allowing harmful bacteria and nutrients to wash into the storm drain and eventually into local water bodies.
