Committed to quality service, environmental stewardship and renewable resources, the Pima County Regional Wastewater Reclamation Department embarked on the largest capital program in its history, which included the $172 million Agua Nueva Water Reclamation Facility. As a single-entity DBO firm, CH2M HILL had 100 percent responsibility and accountability for delivery, from preliminary design, permitting and construction, through acceptance testing and operations and maintenance for 15+5 years. The 32-million-gallon-per-day facility now produces A+ quality effluent and features state-of-the-art odor control technology. Key challenges were meeting stringent contractual/permit effluent requirements and compliance schedules, coordinating shutdown of the old facility with Agua Nueva startup, maintaining strong coordination with other projects and optimizing capital and lifecycle costs.
