Construction work to begin next week on Mapleton Drive

Starting Tuesday, May 26, crews expect to begin preparing a work pit (entry shaft) for the tunnel (auger bore) to be installed under Trillium Creek. An auger will be used to install piles and steel sheets to support the work pit, located on the road and gravel shoulder on Mapleton Drive, near the creek. The work pit will be excavated and the materials removed. In June, an auger bore machine will be placed inside the work pit to create a tunnel under Trillium Creek.

Water Treatment Plant Construction Update

Sedimentation basin demolition – northwest of site

Demolition of the basins and alum room is progressing well, and the crushing of the stockpiled concrete started this week. Crushing the material on site for later reuse reduces truck traffic in the neighborhood.  

Over the last week or so, crews have needed to use the hydraulic hammer more frequently to break up the concrete in the base of the foundation. Unfortunately, this is a very noisy activity. Crews are aiming to be done with most of the demolition mid-next week, and are trying to use the concrete processors (jaws) as much as possible, which are not as noisy as the hammer. Demolition crews are working six day weeks (Monday through Saturday), and averaging 10-hour days, to help get the work finished sooner. We appreciate everyone’s patience during this noisy activity.
