Ajax Water Supply Plant

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.
