Town of Drumheller water treatment plan contains multiple ventilation units. This project will consist of the removal and replacement one of the MUA units, ‘MUA-7’, as a maintenance procedure to provide a new ‘like-for-like’ make-up air unit. This new unit will be suspended at the location of the old obsolete unit and will be tied into the existing controls network to maintain the sequence of operations. The Town of Drumheller Water Treatment Plant is located at 2490 South Railway Avenue, Drumheller, Alberta. The site includes multiple make up air units which were installed in 1985. The ‘MUA-7’ has reached the end-of-life period and the Town intends to replace ‘MUA-7’ as per this project. The ‘MUA-7’ is a ceiling suspended unit at a high level and equipped with two gas-fired furnaces installed in series. The unit has an outdoor air connection at the back of the unit, return air connection at the bottom and front supply air connection. It is planned to replace the existing ‘MUA-7’ with a ‘like-for-like’ unit from Engineered Air that can match the existing dimensions, weight and performance capacity. The equipment is suspended above existing water piping that shall remain and be protected throughout the entire duration of construction.
