Environmental Utilities Director Sean Bigley told the Public Utilities Commission on Jan. 28 that Roseville will begin above-ground construction for two aquifer storage and recovery (ASR) wells in April 2025 and expects about an 18-month construction duration.
Bigley said the two next wells are sited at the Campus Oaks development area (near Blue Oaks) and a Pleasant Grove parcel near Misty Woods. He said downhole drilling and water-quality testing were completed in late 2023 and the above-ground facility designs were finished in 2024.
“Construction [of pumps, piping and above-ground facilities] will begin in April 2025,” Bigley said, noting the timeline targets lower-precipitation months. He said the capital plan envisions two additional ASR wells after the current pair and that staff are monitoring property opportunities for future sites.
On security and resiliency, Bigley described a package of measures funded in the last rate case: perimeter fencing at pump stations and ASR sites, upgraded alarm and surveillance systems, stricter facility access and visitor-identification protocols, and training exercises for water and wastewater staff. He said Roseville hosted Texas A&M Engineering Extension (TEEX) emergency operations training last year and is arranging vendor-led and in-house training for relevant utility staff.
Bigley also told commissioners the department will procure a replacement emergency generator for a dual-purpose pump station and portable backup generators for ASR wells to maintain system pressure in outages. He said staff are strengthening procedures to prevent facility “tailgating” and to increase staff awareness of both physical and cyber threats.
Community programs: Bigley reported the Utility Exploration Center’s “Succulents to Soup” food drive raised more than 6,000 pounds of food and distributed 500 succulent plants; the food went to Saint Vincent de Paul in Roseville.
Ending: Bigley said staff will update the commission as construction starts in April and as security and resiliency procurements proceed.
