Platt/Whitelaw Architects, Inc. is providing architectural design services to the Prime Engineer for this modernization of an 85 MGD water filtration plant, comprising design, plans and specifications for six major buildings at the Plant. Additionally, field verification services, as-built drawings and demolition drawings for the existing headhouse buildings are included in Platt/Whitelaw's assignment. The site has been masterplanned to allow the work to be built in phases, to keep the plant operational.

The plant's architecture, designed by Los Angeles engineer James Montgomery in 1946, is Spanish/Moorish style, strongly responsive to its hilltop site. The masterplan has integrated a public tour and public art in order to involve the public with the protection and conservation of our water supplies. The tour will draw visitors through the plant's processes, informing about each phase of treatment. This project will expand the plant and rehabilitate the existing facilities.

Additionally, at the request of the community, Platt/Whitelaw has studied the feasibility of extending access all the way around Lake Murray, via either a bridge or across the existing dam. The alternate concepts which have been provided for future consideration are: a pontoon bridge which skates on the water like a strider bug; and a walkway attached to the top of the dam, suggesting a pipeline, but open to views of the lake and the canyon below.
