Grass Lake Interceptor Rehabilitation

MCES Project No. 808861

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, is making improvements to the sanitary sewer interceptors along Grass Lake and the Snail Lake wetlands in the Snail Lake Regional Park located in Shoreview, Minnesota. These improvements will repair the aging infrastructure and improve the system’s efficiency and reliability.

The interceptor located along the east side of Grass Lake, is often submerged due to rising lake levels. This inhibits the ability for MCES staff to perform routine maintenance and poses the threat of leaking wastewater into the lake or even draining the lake of its water. In addition, the portion of interceptor that runs along the Snail Lake Regional Park has damaged castings, cracked rings, and exposed manhole structure, posing similar threats to the adjacent wetlands.

Key improvements of this project include:

  • Realigning the Grass Lake interceptor to higher ground
  • Rehabilitating the Snail Lake interceptor
  • Relocating the trail that runs parallel to the Grass Lake interceptor
  • Addition of a cross country ski trail
