North Clear Creek Water Treatment Plant Colorado Department of Public Health and Environment | Lake City, Colorado ■ Design of a high-density sludge lime precipitation treatment facility ■ Civil, structural, mechanical and electrical engineering services ■ Construction management The North Clear Creek Water Treatment Plant is part of Operable Unit Four of the Central City/Clear Creek Superfund Site, listed on the National Priorities List in 1983 due to heavy metal contamination from historic mining. The 400-square mile watershed was impacted by cadmium, copper, manganese and zinc, which was threatening aquatic life and human health. In response, the Environmental Protection Agency and Colorado Department of Public Health and Environment issued a Record of Decision in 2004. Subsequently, in 2010 it was amended to select active treatment as the preferred remedy. WSP was engaged to deliver a full scale, automated high-density sludge lime precipitation facility treating 150–600 gallons per minute. WSP led process development, including bench and pilot studies, and completed full detailed design across civil, structural, mechanical and electrical disciplines. The facility was designed to fit within a historic mining town’s footprint. WSP also provided construction management, commissioning, operator training and a year of operational support. Since 2022, WSP has continued to provide operations and maintenance staffing and off-site engineering support.

Advanced Water Reuse Treatment Plant Design – Albuquerque City of Albuquerque | Albuquerque, New Mexico ■ Advanced industrial water reuse to support sustainable economic growth ■ Evaluation and development of Public-Private Partnership delivery models ■ Achieved a $100-million cost reduction Albuquerque and the State of New Mexico to address long-term water scarcity while enabling industrial expansion and economic growth. The project centered on the planning and design of a 5-million-gallon-per day advanced water reuse facility, capable of recycling treated effluent from high-tech manufacturing processes such as microelectronics and solar production. WSP developed an economic model and conducted a comprehensive assessing both construction and long-term operational costs. The team introduced a novel treatment process that preserved scalability for future capacity expansion while reducing capital expenditures by $100 million. The proposed treatment train included softening clarifiers, ion exchange, reverse osmosis, evaporation and crystallization technologies. This advanced configuration enabled 100% reuse of industrial wastewater, reinforcing As the owner’s representative, WSP partnered with the City of evaluation of Public-Private Partnership delivery models,

■ Mine water treatment plant design ■ Multi-media filtration and reverse osmosis polishing ■ Regulatory compliance

WSP designed and constructed a 10-million-gallons-per-day mine water treatment and polishing plant to manage rising water levels in the Berkeley Pit, a 1,780-foot-deep former open pit copper mine in Montana. Since its closure in 1982, groundwater inflow had been steadily filling the pit, prompting the need for a treatment solution to prevent water from exceeding a critical level. This project was completed in just 15 months under close regulatory oversight. The facility includes multi media filtration and reverse osmosis polishing that treats the interconnected tailings impoundment water to meet discharge standards set by the US Environmental Protection Agency and Montana Department of Environmental Quality. WSP’s integrated design-build approach and strong collaboration with the client facilitated project success. The plant was designed with flexibility to adapt to changing conditions and maintain long-term compliance. Over 90,000 work hours were completed without a safety incident.
