Solids Management Upgrade

Solids Management Upgrade (SMU)

What is MSD Project Clear?

The Metropolitan St. Louis Sewer District was created on February 9, 1954 when voters approved a plan to combine 79 regional sewer districts into one city-wide system for the collection, treatment, and disposal of wastewater.

MSD Project Clear is a long-term effort by MSD, undertaken as part of an agreement with the U.S. Environmental Protection Agency and the Missouri Coalition for the Environment. The goal for this $6 billion, 28-year initiative is ambitious but within reach:

  • Improve water quality for the entire St. Louis region
  • Resolve community issues caused by the nature and design of St. Louis’ legacy wastewater system
  • Keep the public informed with clear and timely updates

Our mission is to protect the public’s health, safety, and water environment by responsibly providing wastewater and stormwater management. Visit our Mission, Vision, Values page to learn more about what we believe.

Why is the SMU project being built?

MSDPC has operated the existing multiple hearth incinerators at both its Bissell Point and Lemay treatment facilities for nearly 60 years. Although these facilities have served the region well and they continue to meet or exceed all air quality standards, their age and the development of newer, even cleaner technology makes replacing them a priority.

  1. Fluidized bed incineration is an environmentally friendly and cost-effective solution
  2. New facilities provide substantially cleaner operations
  3. New technology significantly reduces air emissions

What work is being done on this Project?

The initial concept is to replace the existing 1960s-era incinerators with advanced incineration units for the Bissell Point Wastewater Treatment facility with a total treatment capacity of 240 dry tons of solid waste per day. The Lemay Wastewater Treatment facility will have at least two new units with a total treatment capacity of 160 dry tons of solid waste per day. This work is part of MSDPC’s commitment to the environment and human health. Building modern incineration facilities will provide both cleaner water and cleaner air for the St. Louis region.

How will it be built?

A Request for Qualifications (RFQ) is slated for release in the first half of 2021 as a design-build project. Up to three design-build teams may be short-listed from the qualification submittals received. These teams will then be issued a Request for Proposal (RFP), which will include design concepts that have been developed to approximately 30% completion. The short-listed teams will then be given ample time to develop the design concept to a completion level (roughly 60% complete or more) that will allow the team to submit a fixed price proposal for the project.

At this time, the District estimates the following level of investment for this project:

  • Pre-Selected Equipment: Estimated $140-$160 million
  • Design Build Contract (excluding Pre-Selected Equipment): Estimated $350-$400 million

When will construction take place?

These facilities will be built entirely within two of MSDPC’s existing wastewater treatment plants. Current plans call for construction to begin in 2023 with completion in 2026.
