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.

Contact information

For information regarding construction, please call the construction hotline or send an email to the contact information listed on the bottom of that project’s website.

While the response to COVID-19 continues to evolve, we will continue to monitor and review construction activities and conditions through our field inspectors and their on-site reporting.

We will be using electronic communication methods to share information, should there be additional updates. Subscribe to updates by text or email.

Project Description

Metropolitan Council Environmental Services (MCES), operator of the metro-area wastewater collection and treatment system, rehabilitated, cleaned, and inspected the Lake Street Siphon facility. 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 was conducted to evaluate the existing condition of the facility and determine if repairs were required to ensure future facility reliability. This work included 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 completed work in fall 2021. This work required 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 was closed between Eustis Street and Pelham Boulevard for two to three weeks. Advance notice was provided prior to the road closure.

The Lake Street Siphon facility was successfully rehabilitated and results of the inspection indicated the siphons were in good condition.
