The City of Vista and its Buena Sanitation District were recognized for cost-effectively replacing an aging sewer pipeline running through the environmentally-sensitive Buena Creek area at the annual California Water Environmental Association (CWEA) San Diego chapter awards program.
Dudek’s Art Garcia was recognized as Outstanding Young Professional at the event.
The Buena Creek pump station force main replacement project was overseen by Dudek’s Steve Jepsen, who serves as the contract manager to the City of Vista/Buena Sanitation District for its sewer improvements program.
The project involved replacing 2,300 feet of older ductile iron force main aligned in an oak riparian habitat parallel to the Aqua Hedionda Creek and immediately adjacent to a 33-inch fragile pre-stressed concrete San Diego Water Authority potable water pipeline. Replacing the force main would be challenging if not impossible.The design team discovered a route that was shorter than the original alignment; required no permitting or mitigation because it avoided environmental and cultural resources; and it took advantage of an old sewer easement for prior rights.
“A partnered approach was essential to success during both design phase and construction phase,” Jepsen said. “The partnering approach was particularly important during construction, especially night time construction of the connections, among the Buena Sanitation District engineers and operators, Encina Joint Powers Authority pump station operators, the contractor crew and the construction manager and inspectors.”
