Crane Removal at the Water Treatment Plant

Water Treatment Plant Construction Update

Tomorrow afternoon, Wednesday, November 30, a large mobile crane will be delivered to the water treatment plant. This crane will be used to take down the red tower crane, one section at a time. From Wednesday through Friday, several flatbed trucks will be traveling to and from the site, carrying sections of the crane. Trucks will use both Mapleton Drive and Kenthorpe Way entrances to enter the plant site, and will exit on Kenthorpe Way.

Crane removal is expected to be complete by the end of the week. During this time, there will be an increase in truck traffic on both Mapleton Drive and Kenthorpe Way. Please expect some short-term traffic delays during this activity.

Thank you for your patience and understanding.
