Pumping Station 18 Force Main

MMSD is in the process of constructing a series of projects to increase wastewater conveyance capacity.  Part of this series of projects is the construction of the Pumping Station 18 Force Main (PS18FM).  This project will involve the installation of a buried 48" pipeline along the project route displayed in the "Project Route Map" diagram below.  Much of the project will be constructed in non-roadway areas during winter and early spring months.  

In early spring, construction activities will be moving into Broadway.  Construction along Broadway will result in lane closures, and one-lane traffic in each direction in construction areas.  Access to residential addresses and business will be maintained throughout the project.  Night work will be used where necessary in order to maintain that access.  To learn more about the road work on Broadway, check out our Newsletter and some macro-scale depictions of  Broadway Traffic Control

With our extensive amount of work planned for Broadway, communicating with the public will be especially critical for this project. To make this process easier we are going to be keeping you up to date as much as we can. As the construction work progresses we will be providing new information through this website and over twitter.  You can also sign up for regular emailed project updates.

Quick Facts

  • There will be 15,000 total lineal feet of new 48" diameter sanitary forcemain constructed.

  • Approximately 600 feet of underground tunneling will be performed to install the forcemain under the Yahara river and to avoid disrupting traffic on busy roads.

  • The Pumping Station 18 Force Main will be capable of conveying 66 MGD of flow. This about the same amount of average flow that passes through the Yahara River between Lake Monona and Lake Mendota.
