The Ajax Water Supply Plant was designed and constructed for the Regional Municipality of Durham. Hatch Mott MacDonald was in charge of the design of this facility. The design required a great deal of effort in order to satisfy functional, aesthetic, and environmental demands. Its location, adjacent to parkland near residential areas, dictated a mixture of industrial architecture and recreational landscaping. The participation of affected residents, building committees, and the general public in the design process resulted in a park that can be enjoyed as a meeting place beside Lake Ontario and a building providing the water needs for the Ajax/Pickering area.
HMM’s design responsibilities included civil, architectural, structural, electrical, mechanical, instrumentation and control, and process design for the $72 million project. In addition to the design responsibilities, HMM provided full-time site supervision and contract administration. The facility is designed with the provision that its production capabilities can be doubled from 164 ML/d to 327 ML/d. The project included the construction of a separate reservoir and a 2135 mm diameter x 2680 m long intake.
