It was out with the old in order to bring in the new Monday afternoon as the 1924 pump building at the Washington Water Treatment Plant was demolished as part of the project to renovate Washington?s water system.
City administrator Brent Hinson said the building will be removed and a driveway to the plant will be installed leading up to the renovated 1992 building. He said the $5.5 million project to renovate the water plant project is going smoothly and that for two months the city has been on the new reverse osmosis filtration system. There also has been an addition added to the 1992 building, which will now be used for such things as storage and office space.
?The 1924 building was in very poor shape and would have cost a lot more to renovate than to do the 2017 addition,? he said. ?It was also a better flow for the treatment process and the 2017 addition is actually larger in both ceiling height and overall size.?
The new addition includes 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. Hinson said the demolition is the visible work being done at this point. Additionally workers are improving the site with paving. Hinson said there are three phases planned to pave the site and one is already complete. He said the northeast side of the building is the next area that will be paved before the driveway is added.
The project also will include 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.
?Two months ago we got the new system operable, but that was prioritized because of the condition the system was in, and that made for a good project flow,? Hinsons aid. ?We have the new system operational, but after that we still had eight months of project left. There is just a lot to do.?
The project was paid for in part with a grant from the Iowa Economic Development Authority (IEDA) of $600,000.
