Water Treatment Plant Construction Update

A 100 ton mobile crane arrived on-site this week

This week at the water treatment plant (WTP) construction site, work continued on installing a dewatering system to control ground water in the finished water pump station. A 100 ton mobile crane also arrived on-site, and excavation of a new clearwell access ramp for the auger cast crane was completed.

Next week will be a short week, with no work occurring on Thanksgiving Day, the Friday after Thanksgiving or Saturday November 30.

The Partnership has recently reformatted the construction updates to include more detail on construction activities, purpose and duration of work.
