IEUA seeks $4m expansion of SCADA integration capacity
Inland Empire Utilities Agency, California · Meeting date: October 14, 2026 · Published: October 15, 2026
IEUA’s Engineering, Operations & Water Resources Committee advanced a proposal to add four SCADA integrators under master services contracts worth up to $4 million over a potential five-year term. Staff said rising integration demand has exhausted the available capacity of the agency’s two existing prequalified providers.
Key points
- The proposed contracts would cover a three-year term, with two optional one-year extensions, for an aggregate not-to-exceed value of $4 million.
- Carollo Engineers, Partners in Control dba Enterprise Automation, Rockwell Automation and Wunderlich-Malec Engineering were recommended following a qualifications process.
- IEUA said its existing integrators, ETEC and CSI, will remain in place; the new contracts are intended to expand rather than replace the available consultant pool.
- The scope includes programming, plant workshops, site visits, testing, training, startup support and emergency on-call services for water and wastewater projects.
Full report
Inland Empire Utilities Agency is seeking to widen the pool of firms available to integrate supervisory control and data acquisition systems across its water and wastewater capital programme, after staff said the capacity of its current providers had been maximised.
At its 14 October Engineering, Operations & Water Resources Committee meeting, staff recommended master services contracts with Carollo Engineers, Partners in Control dba Enterprise Automation, Rockwell Automation and Wunderlich-Malec Engineering. The contracts are proposed for three years, with two one-year extension options, and carry an aggregate not-to-exceed value of $4 million over the potential five-year term.
Committee members indicated that they would move the item to consent. The meeting record does not show a final approval vote.
Acting principal engineer Pierre Cayet said IEUA uses system integrators to programme SCADA-related projects, enabling equipment to communicate within plants and allowing operations personnel to monitor and control processes. The agency currently has two prequalified integrators, ETEC and CSI, which staff said have performed well and remain important resources. However, increased system-integration demand has exhausted their available capacity.
The proposed procurement is therefore intended to supplement, rather than replace, the existing providers. IEUA’s operational technology department can also undertake programming work, Cayet said, but is supporting projects across the agency and does not have the capacity to perform all such work.
The contract scope would cover SCADA integration services typically needed on IEUA water and wastewater projects. The firms would conduct workshops and site visits to understand plant operations, and would work with engineering, operations and OT staff during programming, testing, training and startup. They would also provide emergency on-call support.
IEUA published a request for qualifications on PlanetBids in March 2026 and received 10 statements of qualifications. Five firms were interviewed and four were selected. Staff said five firms were not interviewed because references either did not check out or could not be verified, while one firm was not selected after interview because of a lack of local presence.
The move comes as IEUA continues work on major treatment and recycled-water infrastructure. At the same meeting, staff reported that the RP-1 solids thickening project was 701 days into construction, or 44% through its total construction duration, while the agency was also scheduled to consider a $1.59 million contract for a monitoring well supporting early engineering for the Chino Basin Program.
