Integrated Management Plan (IMP) for Wastewater & Stormwater

The City of Columbia has developed an Integrated Management Plan (IMP) to meet critical infrastructure needs for improving our community waterways. The goal of the plan is to establish adaptable and affordable long-term recommendations that meet Columbia’s wastewater and stormwater management needs while addressing Clean Water Act obligations.

This plan will help Columbia target investments in our wastewater and stormwater programs to:

  • Protect public health & safety
  • Improve quality of life 
  • Provide sustainable service for the future
  • Improve water quality
  • Achieve regulatory compliance
