Motor Control Center (MCC) Update for Water Plant No. 2

District is updating the electrical controls for water plant no. 2 (located adjacent to the elevated storage tank on Mason Road). The existing control center has reached the anticipated design life and the technology is outdated. The District is updating the control center to current regulations utilizing technology that will seamlessly interface with the other District facilities.

Project is currently advertising for bidding and construction is expected to commence in Summer 2019.

Bent Creek Court Drainage Improvements

The District will install a flap gate on the storm sewer outfall pipe that drains Bent Creek Court into the Main Channel located south of the cul-de-sac. When water in the main channel gets high, this flap gate will prevent water from backing up into Bent Creek Court.

Construction is expected to commence in Summer 2019.

Improvements to Raw Water Tanks at Surface Water Treatment Plant

The District will install a floating mixer in each of the raw water storage tanks at the Surface Water Treatment Plant located off of Skinner Road.

In addition, stairs and walkways will be installed as part of this project to improve operator access to the tanks.

Construction is expected to commence in Summer 2019.
