Capital Program


The regional wastewater collection and treatment system has an estimated replacement value of approximately $7 billion. Between 1970 and 2010, we focused our capital investments primarily on developing an efficient and effective wastewater system that will serve the region well for many decades.

These investments have included interceptor system capacity expansion and extension to serve the long-term service area (2040 and beyond), as well as consolidation, expansion, and quality upgrades of the regional wastewater treatment plants. In recent years, the capital investments have shifted primarily to preservation of this valuable regional infrastructure.

The 2017-2022 Capital Program supports the level of service to MCES customers, including:

  1. Preserving the value and performance of the region’s wastewater assets.
  2. Complying consistently with water, air, and environmental permits.
  3. Conveying and treating wastewater safely with minimal backups or spills.
  4. Leading by example with respect to energy conservation and water conservation/reuse.
  5. Being a good neighbor with respect to odors, traffic, noise, and visual aesthetics.
  6. Providing capacity consistent with the regional wastewater system plan and approved local comprehensive sewer plans.
  7. Coordinating public infrastructure asset preservation work.

The Environmental Services (MCES) Capital Program is a component of the Council’s unified budget plan. MCES plans capital spending for new treatment plants, interceptors and/or improvements of the metropolitan disposal system. The capital program provides investments to preserve and rehabilitate existing wastewater infrastructure, meet more stringent water and air quality regulations, and expand the system capacity to meet regional growth needs. The capital program is prepared, reviewed, and approved on a yearly basis to account for new programs and/or adjustments to the plan.
