Lake Street Siphon Inspection and West Meters Odor Control Modifications

MCES Project No. 807626

Understandably, the spread of COVID-19, also known as the coronavirus, has raised questions about the status of Metropolitan Council Environmental Services (MCES) plant and interceptor construction projects. Please note the following:

  • Construction on wastewater treatment plants and sewer interceptors will continue. The contractors are following working environment protocols (asking employees to stay home if they are sick, social distancing, etc.) as outlined by public health agencies.

  • Some project staff are working remotely while others remain on-site to ensure proper oversight of the project. Staff will stay connected through emails, conference calls, and web-based meetings to manage construction activities.

Project Description

Metropolitan Council Environmental Services (MCES), operator of the metro-area wastewater collection and treatment system, will be rehabilitating, cleaning, and inspecting the Lake Street Siphon facility starting in fall 2020. The facility is located north of the Lake Street Bridge and consists of a headhouse structure on the west bank of the Mississippi River, a tailhouse structure on the east bank, and three 60" diameter siphon pipes connecting the structures buried under the riverbed.

The facility was constructed in 1937 and last inspected in 1993. An inspection is being conducted at this time to evaluate the existing condition of the facility and determine if repairs are required to ensure future facility reliability. This work includes making permanent and temporary improvements to odor control measures, sewer structures, and the facilities at the headhouse and tailhouse.

 The Lake Street Siphon facility contruction area is located south of the Lake Street bridge and consists of a headhouse on the west bank of the Mississippi River, a tailhouse structure on te east bank, and three 60 inch diameter siphon pipes connecting the structures buried under the riverbed.

Crews began inspecting the facilities and making improvements in late 2020 and anticipate work to be completed in fall 2021. This work will require Winchell Trail to be closed for six months between the headhouse work site and the trail head at W River Parkway. Mississippi River Boulevard N will be closed between Eustis Street and Pelham Boulevard for two to three weeks. Advance notice will be provided prior to the road closure.
