Greenmeadow Sanitary Interceptor Project

Blast Update Sept 6 2019

We have received word from the contractor that a rock tunneling blast will occur TODAY BETWEEN 10am and 11am near the intersection of Joellen Dr and American Ave. As with previous blasts, those nearby will experience a low rumble when the blast is set off.

Construction Update - Sep 6, 2019



This project will include installation of a new sanitary interceptor sewer from the intersection of Greenmeadow Dr. and Michigan Ave. to the intersection of College Ave. and Sentry Dr. in 2018 and 2019. This sewer will allow the elimination of the Greenmeadow and Woodfield pump stations.

This week’s work:
• Continued process of removing tunnel boring machine from tunnel
• Continued sanitary interceptor sewer installation on Dopp St along with sanitary and water lateral work
• Second underground crew on Joellen Dr continuing north from Stewart Hill Dr towards American Ave
• Finished concrete restoration work (curb, driveway approaches, sidewalk) on southbound S Moreland Blvd from W St Paul Ave to Dopp St

Next week’s work:
• Finish process of removing tunnel boring machine from tunnel
• Finish sanitary interceptor sewer installation on Dopp St and begin sewer installation heading to the north on Joellen Dr
• Continue second underground crew on Joellen Dr at Stewart Hill Dr and continuing north towards American Ave. Rock blasting operations may also occur at this location daily. Those nearby may notice a low rumble when a blast is set off.
• Begin installing 36” diameter sewer in tunnel running from Madison St/Joellen Dr shaft to Lowell Park shaft

Access to homes for emergency vehicles and residents will continue to be maintained in the closed section.
