Solids Management Upgrade (12565)

Solids Management Upgrade (SMU) at Bissell Point and Lemay WWTF (Project Number 12565)

UPDATE November 10, 2021

Communication to Interested Parties: New Diversity Video, Diversity Workshop Follow Up

As you will recall, the District conducted a Diversity Workshop over the summer on the Solids Management Upgrade project. Today, we are releasing a new video on MSD’s Minority and Women Business Enterprise participation program, which will be of interest as parties seek to develop their teams. A link to this video is provided below, along with and several follow up resources from the Diversity Workshop itself.

Our thanks to everyone who participated the SMU project Diversity Workshop. This was a good opportunity to review MSD’s diversity procedures and the importance that MSD places on its diversity programs, and for MWBE firms to discuss the project and their capabilities to DB teams.

About the Project

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 Wastewater 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 

Since our Industry Day presentation in 2020, the District and the Owner’s Representative Team for this project have continued moving forward, making some changes and refinements to the process.

What work is being done on this project?

The treatment process components that will be included have been refined. We have concluded that some ancillary equipment will likely not be a part of the project, including a wet electrostatic precipitator system, a selective non-catalytic reactive system, and a secondary heat exchanger. The Lemay plant scope will now include the renovation of the existing Grit and Screen Building into a new Maintenance Facility. All other major process components originally contemplated for the project remain a part of the scope at this time. Major siting decisions have also been completed, as noted on Industry Day. 

The overall concept is to replace the existing 1960s-era incinerators with advanced incineration units for the Bissell PointWastewaterTreatment facility with a total treatment capacity of 240dry 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. 

This project will include fluidizing bed incineration (FBI) and centrifuge dewatering systems at each of these two plants. For a better sense of each of these treatment plants and the people who make them work, below are two short videos produced by the District to celebrate the 50thanniversaries of both sites—Lemay’s in 2018 and Bissell’s in 2020.

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. 

What is the timeline?

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. One fixed price design build contract will be awarded for the upgrades to both facilities. The project is in preliminary design, and the District is currently in the final stages of completing a Request for Proposals (RFP) forpre-selecting the FBI equipment, which will be posted at theMSD Plan Room. To ensure your firm is advised when the RFP is available, be sure to register at the link at the bottom of this page. A Request for Qualifications (RFQ) is also planned for 2021 for interested design-build teams, with up to three teams being short-listed and asked to submit a proposal in 2022. The overall timeline is below:

Frequently Asked Questions

See the section titled “timeline” for more information; but generally, the District anticipates releasing the design-build RFP in July 2021. The District anticipates reviewing qualifications and short-listing up to three design-build teams near the end of 2021 and issue a Request for Proposal to the short-listed teams. A notice-to-proceed would be issued to the selected team in the second quarter of 2023 and the team would be given approximately 42 months to complete the project. 

As outlined in the Industry Day presentation, the District will utilize fluidized bed incineration with centrifuge dewatering as the primary processes included in this project. Other ancillary processes will of course support these systems. 

The District is not anticipating implementing a direct energy recovery system for this project with the initial construction project; but will incorporate space provisions for including it in the future. 

No. The District will undertake a pre-qualification process for the equipment and will name the pre-qualified firms in the specifications as acceptable. Firms not pre-qualified will not be accepted. 

No. The District is committed to this procurement process and has begun implementing projects utilizing this method. 

Yes. The District is looking to work with the most qualified teams that have proven ability to deliver a project of this magnitude and demonstrate the best approach for completing it in a quality, timely, and cost-effective manner. 

Due to the current environment related to Covid-19, the District is not conducting in-person meetings. However, the any interested party may contact the District to schedule a video-conference with project team management.
