Ten Pump Station Improvements:

• Owner: City of Thousand Oaks
• Cost: $4,000,000

The City of Thousand Oaks brought Perliter & Ingalsbe on board to provide engineering and construction services to upgrade ten existing pump stations involving 25 individual pumps ranging in size from 20 HP to 100 HP. The first phase included field investigation and a study to determine required improvements at each site. The second phase of the project included detail design involving mechanical, civil, structural, electrical, instrumentation and controls. The third phase included bidding services and construction management with continuous on-site inspection.
