Tampa Water Department advances cutting edge technology. 06/29/2026 Tampa Water Department advances groundbreaking technology. The Tampa Water Department is taking a major step forward in its efforts to enhance drinking water quality, as new testing confirms the effectiveness of its innovative Suspended Ion Exchange (SIX) treatment technology in reducing PFAS, commonly known as "forever chemicals." Recent testing conducted by an independent consultant evaluated SIX's ability to remove PFAS from raw water at the David L. Tippin Water Treatment Facility. Results showed that the SIX system removed approximately 30% of PFAS compounds found in its water source. While this technology was initially chosen to help remove naturally occurring organic matter, testing confirmed its ability to remove PFAS as well. By removing both organic matter and PFAS early in the treatment process, SIX delivers multiple water quality benefits through a single treatment technology. SIX will not only allow other treatment processes work more effectively, but it will also position the Tampa Water Department to meet future drinking water regulations. In addition to improving water quality, SIX is expected to lower both future construction and operating costs. By helping the rest of the treatment system work more efficiently, SIX reduces the scale of treatment improvements needed at the plant. Studies conducted during project planning found that using SIX could save more than $80 million in future facility improvement costs compared to other treatment options. The technology will also significantly reduce ongoing treatment costs. During a 10-month pilot program, SIX demonstrated the ability to eliminate the need for some treatment chemicals while substantially reducing the use of others, resulting in projected annual savings of approximately $2 million. The latest test results come as the Tampa City Council has approved moving forward with the design phase of the SIX facility. The Tampa Water Department is partnering with the Tippin Water Team (Carollo Engineers, Garney Construction, Wharton Smith, Inc., and PWNT Technologies) to design and construct the new facility, with completion expected in 2032. Once operational, the SIX facility will be the first of its kind in North America and the largest SIX installation in the world, positioning Tampa as a global leader in advanced water treatment innovation.

New facility will add 10 MGD of treated water capacity and strengthen long-term water reliability for western Placer County. Release Date: June 16, 2026 AUBURN, Calif., June 16, 2026 - Placer County Water Agency (PCWA) has selected Carollo Engineers to provide construction management and SCADA programming services for the new Ophir Water Treatment Plant (WTP), a major infrastructure investment designed to meet growing regional demand and enhance system reliability. The project represents a long-planned expansion of treated water capacity as PCWA's current facilities approach peak operational capacity during high-demand summer periods. PCWA is the largest water service provider in Placer County, delivering treated water to approximately 192,000 people and supplying wholesale water to neighboring agencies. The Ophir WTP will initially add 10 million gallons per day (MGD) of treated water capacity, enough to serve 10,000 families, as the first phase of a multi-stage program allowing PCWA to scale the facility over time. Situated on a 22-acre site along Ophir Road in Auburn, California, the project will provide a critical new supply source while supporting long-term planning for communities across western Placer County. The Ophir site is master-planned to ultimately support up to 30 MGD of treatment capacity, offering a scalable and resilient solution to meet long-term regional water needs. The total estimated construction cost of the Ophir WTP Phase 1 is approximately $210 million. "This is a long-term investment that's been planned for decades," said PCWA General Manager Andy Fecko. "The project is structured so growth pays for growth, with water connection charges funding the capacity needed for new customers. An added benefit is that it also improves reliability and resilience for the customers we already serve." The new facility will relieve capacity constraints at PCWA's Foothill Water Treatment Plant, the agency's largest facility, which currently operates near its limits during high-demand summer months. Once operational, the Ophir WTP will enhance system flexibility and provide critical redundancy across the regional water network. The facility will also allow PCWA to extend its annual construction and maintenance window by roughly two months, enabling essential upgrades and rehabilitation work at the Foothill Water Treatment Plant during lower-demand periods. Carollo will manage schedule and cost tracking, inspection, documentation, and project coordination during the plant's initial phase, with work completed in line with project specifications, safety standards, and quality requirements. In addition to construction management services, Carollo will perform SCADA programming for the project. "We are honored to support PCWA in delivering this transformational project," said Carollo Principal-in-Charge Keith Corcoran. "The Ophir Water Treatment Plant will deliver a resilient, reliable water supply for the community while reinforcing the region's critical water infrastructure for generations to come." Construction is anticipated to begin in fall 2026, with the facility expected to be operational by 2030. For project updates and additional information, visit www.pcwa.net.

Carollo Engineers appoints Farhan Shaikh as vice president, retains Alan Roberson as water policy consultant. WALNUT CREEK, Calif. - As water utilities navigate increasing pressure to modernize infrastructure and comply with evolving federal regulations, Carollo Engineers is strengthening its capabilities in both areas with two strategic appointments. The firm announced today that Farhan Shaikh has joined as vice president and senior strategic advisor for digital transformation and solutions. Alan Roberson, a nationally recognized leader in drinking water policy and regulation, has also been retained to support policy and advocacy efforts. Shaikh brings deep experience in helping utilities deploy supervisory control and data acquisition (SCADA) systems, asset management platforms and data analytics tools that improve operational efficiency and decision-making. Roberson's more than three decades of experience developing federal drinking water regulations strengthens Carollo's ability to keep clients ahead of anticipated regulatory requirements and develop cost-effective compliance strategies. "Farhan guides utilities in translating digital water concepts like real-time monitoring, predictive maintenance and integrated data platforms into implementation plans with clear timelines and measurable outcomes," said Carollo managing director of client services Scott Hoff. "With Alan's decades of experience shaping national drinking water policy, we help utilities anticipate and prepare for upcoming regulatory changes - from per- and polyfluoroalkyl substances (PFAS) standards to Lead and Copper Rule Revisions. Together, they strengthen how we support clients from early planning through implementation." Digital partners.
