Pennoni Associates Inc. prepared detailed mechanical and electrical design, construction drawings and specifications as the project engineer under the Layne Christensen Company for the expansion of a 3 million gallon per day (MGD) water treatment facility located in Newark, Delaware.

The City of Newark owned and operated the Curtis Water Treatment Facility as a 3 MGD facility with limited infrastructure in place to expand to 5 MGD.  Since the plant was originally commissioned in 1993, the treatment equipment currently in place went out of manufacture.   The schedule and complexity of the proposed upgrade of the treatment plant required a design/build approach.  Pennoni was responsible for design of mechanical, process, and controls upgrades and construction coordination.  A customized retrofit design was prepared to upgrade the treatment plant.

At the onset of the project, the Layne/Pennoni team determined that it would be beneficial for the City to upgrade the entire plant control system to create an integrated controls network for all five units.  This recommendation was adopted by the City and incorporated into the project scope.

Layne and Pennoni assisted with plant startup and the project was completed in 2008.  Startup was accomplished while maintaining continuity of service to the City of Newark Customers.
