Watermark is
providing engineering services to Lewis and Zimmerman Associates (LZA), as part of a Value Engineering (VE) team
assembled to review the design of the new water treatment plant (WTP) and associated reservoir pump stations and
pipelines. The WTP is a high profile project for the town, and the VE reviews were conducted at the conceptual
(10%) and preliminary (30%) design milestones.
Watermark reviewed the design engineer’s plans and specifications, and developed alternatives in the civil-site and
process/mechanical areas of the project. Pipe materials, intake configurations, process equipment, chemical feed
systems, and plant layout alternatives were developed. Capital costs, annual operating and maintenance costs and
Life Cycle Cost Analyses were developed for each alternative.
The design engineer and the town reviewed the suite of VE suggestions and selected several for incorporation into the
final design documents.
