Comment deadline for the proposed Interceptor Chemical Odor Control Project

Date: Monday, May 3, 2021

Time: 5:00 PM -


The Metropolitan Council is accepting public comments on its proposed Interceptor Chemical Odor Control Project. The project would improve odor and corrosion control in MCES’s regional sanitary sewer system at 16 sites in 14 municipalities.

MCES proposes entering into two contracts to support odor and corrosion control within the regional sanitary sewer system:

  1. A design-build contract would provide engineering and construction services for odor and corrosion control systems.

  2. A separate contract would provide for operations, maintenance, and replacement of 16 odor and corrosion control systems currently located within the sanitary sewer system. This contract would be for 10 years with potentially two 5-year renewals.

The contracts would replace an existing arrangement with a vendor providing similar services. The odor and corrosion control equipment is used primarily at wastewater pumping stations (also known as lift stations) and wastewater flow metering stations. Liquid calcium nitrate is injected into the wastewater flow at these sites. Calcium nitrate is a natural compound that reduces hydrogen sulfide odors and minimizes corrosion in the system.
