Kokosing/Plocher JV to Proceed on MSD Upgrades

Updates to Bissell Point and Lemay Wastewater Treatment Facilities Projected to Create New Jobs, Improve Air Quality, and Reduce Ongoing Maintenance Costs

Kokosing/Plocher (KP), a joint venture between Kokosing Industrial, Inc. and Plocher Construction Company, Inc. has been granted Notice To Proceed on the Solids Management Upgrades (SMU) project by the Metropolitan St. Louis Sewer District (MSD). Part of MSD’s Project Clear (MSDPC), the nearly $900 million SMU project will improve air quality, increase energy efficiency, lower operating and maintenance costs, and create more than 200 new jobs during construction and new high-tech jobs after completion.

“Over the last two years, the Kokosing/Plocher team has collaborated extensively to optimize the design to benefit MSD and MSD’s customers,” says Dennis Tinkler, PE, Project Manager with Kokosing/Plocher. “Leveraging our team’s experience in the design, construction, and operations of solids treatment, we aim to deliver world-class facilities that are safe, clean, reliable and efficient to operate over the coming decades.”

“We are excited about the opportunity to continue our working relationship with MSD to make much needed improvements to these plants,” said Nick Kampwerth, PE, Deputy Project Manager with Kokosing/Plocher. “As the local partner of the Kokosing/Plocher team, we are proud to be a part of such a unique project that will provide the means of efficient and environmentally friendly handling of biosolids for the metro St. Louis community now and for generations to come.”

SMU will design and construct new facilities under a design-build approach, equipping with industry leading technology for the stabilization of biosolids at the Bissel Point and Lemay wastewater treatment facilities. Using fluidized bed technology, the new facilities will result in a more environmentally friendly, cost-effective, and energy-efficient operation. The SMU will be designed by a team of engineers, led by Crawford, Murphy & Tilly (CMT).

“Given MSD’s status as the nation’s fourth-largest sewer system, this project is unique in both size and complexity,” says Design Lead and CMT Sr. Vice President and Director of Water Resources Raed Armouti, PE. “The CMT team is honored to be trusted with design on this landmark project, which will benefit MSD and the communities it serves for many years to come.”

The improvements implemented through SMU are projected to:

  • Reduce air emissions by 70% – a significant leap forward in air quality enhancement for the communities MSD serves
  • Lower the ongoing maintenance costs currently associated with operating facilities more than 60 years old that uses technology 40 years older
  • Create 200 new jobs during construction, as well as permanent high-tech positions upon completion

The utilization of Design-Build is targeted at helping MSD save time on construction while also reducing risks of construction overruns. Kicking off on July 24, 2023, the project has completion planned for fall 2028. Groundbreaking is set for April 2024, and final design will continue through fall of the same year.

MoDOT, MSD, 12 Local Government Agencies To Unveil $1B+ in New Infrastructure Construction Projects


Officials from the City of St. Louis and four surrounding Missouri counties will join leaders from the Missouri Department of Transportation, Metropolitan Sewer District, U. S Army Corps of Engineers, East-West Gateway Council, Meramec Regional Planning Commission, Boonslick Regional Planning Commission, Great Rivers Greenway and the Hoffman Family of Companies to unveil more than $1 billion of new road, bridge and sewer construction projects before hundreds of construction contractors and interested suppliers at the 2022 Investment in Infrastructure Expo to be held February 22 at the St. Charles Convention Center.

Sponsored by the SITE Improvement Association, this annual event will include presentations about upcoming projects, a financial outlook by the Federal Reserve Bank of St. Louis, a panel discussion featuring three regional planning commissions and a trade show featuring construction industry suppliers and other exhibitors networking with Expo attendees and project owners. The last in-person Expo in 2020 attracted more than 400 attendees and 35 exhibitors, and this year’s event will likely attract many more due to the heightened increase in infrastructure investments being planned at all levels of government. For a short video highlighting the 2020 event, click here:

“The infrastructure projects being unveiled in this area in 2022 are only the tip of the iceberg of what is coming thanks to the recently passed Infrastructure Investment and Jobs Act by the federal government and other local and state stimulus spending,” said Jeremy Bennett, Executive Director of SITE. “We will provide participants a look at what lies ahead in terms of these infrastructure investments in our region that will enhance our competitiveness, create good jobs and make our economy stronger for the long run.”

            The Expo will begin at 1:30 pm with four concurrent presentations outlining more than $1 billion in new construction work and what prospective bidders for that work need to know. The trade show and networking session will then be held from 3:45 – 6:00 p.m. in the exhibit hall, with refreshments available at no additional cost.  Presenters scheduled from 1:30 – 3:45 pm include the following:
