City water plant renovation to be completed by summer

By David Hotle, The JOURNAL

While the cold weather has put renovation work on the Washington Water Plant slightly behind, Washington City Administrator brent Hinson said the plant still is on track to activate the reverse osmosis system early this summer.

Hinson said he expected the new water purification system to be activated in early June. He said even after the new filtration system is turned on, the $5.5 million project to renovate the water plant won?t be complete.

?Even after the reverse osmosis system is activated, we will be continuing the renovations,? he said. ?We have the work scheduled like this because the plant has to continue operating even while the renovations are being done.

To that end, the building housing the plant is being expanded with an addition on the south side. The addition will include the reverse osmosis treatment skids, a dedicated electrical room, chemical feed rooms, HVAC room, generator and power service combinations, and a new control system.The project, which began late last year, is scheduled to happen over an 18-month period. The project includes construction of a new building addition, demolition of the existing pump building, abandonment of the 1992 underground clearwell and pump, addition of a chemical feed or aerator on top of an existing 2015 ground storage reservoir, and reinstallation of the existing high service pumps within the building.Hinson expects the project to be complete sometime in the spring of 2019. The project ws paid for in part with a grant from the Iowa Economic Development Authority (IEDA) of $600,000.
