Contra Costa Water District is designing upgrades to the automated data acquisition system (ADAS) at Contra Loma, Martinez, and Los Vaqueros dams to replace end‑of‑life PLC-based monitoring components. Designs are at 99% for Contra Loma/Martinez and will finish in early 2027 for Los Vaqueros, with construction planned in FY27‑FY28 and an estimated combined construction value of about $1,680,000. OT/SCADA and controls vendors can target upcoming hardware, networking, and integration work and help the district refine specs before construction procurements are released.
Pre-RFP
$1,680,000Jul 8, 2026The district is constructing Phase 1 of the Los Vaqueros Dam intake gate rehabilitation project to address reliability issues with Gates 1–4, including a leaking and corroded hydraulic cylinder. Current work includes inspecting Gates 1–5 and replacing cylinder 1, with Phase 1 construction underway and expected to finish by the end of 2026 at an estimated cost of $3,367,000. While the primary contract is already in place, vendors of hydraulic equipment, coatings, and maintenance services can target future phases or long‑term support needs for these critical gates.
Contract Award
$3,367,000Jul 8, 2026CCWD has competitively selected two consultant teams, Carollo Engineers and Water Works Engineers, for FY27–FY28 WTP Improvements Program design services. The Board will consider professional services agreements on July 15, 2026, totaling $2,489,000 ($930,000 in FY27 and $1,559,000 in FY28) for design work on ozone generators, filter media, blowers, pumps, structures, and access improvements across Bollman, Randall-Bold, and Brentwood WTPs. This locks in engineering incumbents for upcoming design scopes but highlights a pipeline of future construction projects contractors and equipment vendors should watch.
Contract Award
$2,489,000Jul 8, 2026GEI Consultants currently provides design services for the Untreated Water Reservoir Rehabilitation program and has supported several completed and in‑progress dam projects. Staff plans to bring an amendment to extend GEI’s UWRR design services for FY27–FY28 to the Board on August 5, 2026, to maintain continuity for ongoing and new projects. While design work is effectively sole‑sourced to GEI for this period, construction firms and specialty subs can use this as insight into the pipeline of dam and levee projects that will move toward bidding.
Contract Award
$991,000Jul 8, 2026West County Wastewater is issuing FY 2027 bulk chemical purchase orders for sodium hypochlorite and ferric chloride, using Bay Area Chemical Consortium contracts. Univar will supply hypochlorite up to $1,197,000 and Kemira will supply ferric chloride up to $708,500, both funded in the FY 2027 budget. Competing chemical vendors and odor/control or biogas consultants gain insight into incumbents, expected volumes, and can pursue future BACC bids or process-improvement work around disinfection, H2S control, and biogas optimization.
Contract Award
$1,905,000Jul 1, 2026The district is finalizing design (90% complete) for toe drain improvements at Los Vaqueros Dam, including a new pump system to route drain flows above Kellogg Creek’s bank to address DSOD-identified stability concerns. Construction is planned in phases, with in‑creek work starting September 2026 and full build‑out by early 2027; award of the project is targeted for October 2026 with an estimated construction cost of $1,000,000. Civil and mechanical contractors and environmental firms should track this as a near‑term bid for dam safety and creek work.
Active Opportunity
$1,000,000Jul 8, 2026Contra Costa Water District is moving ahead with a PLC and RIO modernization at the Randall-Bold Water Treatment Plant, including SCADA integration and cyber upgrades. A competitive RFP to select a system integrator will determine the final project cost, with Schneider Electric Modicon hardware sole-sourced for about $468,000 of a $2,876,000 budget. The RFP favors highly qualified water/wastewater control integrators; work will occur around FY27–FY28 winter shutdowns, creating a live opportunity for controls, SCADA, OT security, and panel fabrication firms.
Active Opportunity
$2,876,000Jul 8, 2026CCWD will amend its legal services agreement with BKS Law Firm, adding $1,541,000 for FY27 and $1,498,000 for FY28, for a total of $3,039,000 through FY28. This large multi-year allocation confirms BKS as the primary outside counsel for the district. Other law firms and specialized consultants should treat this as clear incumbent intel and focus on niche support, conflict overflow, or positioning for any post-FY28 competitive process.
Contract Admin
$3,039,000Jul 4, 2026A blanket order for Ellucian Company LLC IT software maintenance totaling $782,480 is listed under Fund 11. This confirms Ellucian as the district’s core administrative/ERP or SIS platform with substantial annual maintenance spend. While primary selection is complete, this creates ongoing opportunities for consulting, upgrades, reporting projects, integrations, and data initiatives around the Ellucian ecosystem.
Contract Award
$782,480Jul 8, 2026Delta Diablo is extending its engineering contract with Harris and Associates by $200,000 to complete added environmental and design work for the Manhole, Gravity Interceptor, and Easement Road Improvements Phase 2 project. Design is at 90% with bid advertisement targeted for January 2027 and a total project budget of $14 million. The amendment covers a Phase II ESA and added flow control structures, signaling upcoming construction procurement where civil contractors, environmental firms, and materials suppliers can prepare to compete.
