Staff Report
July 21, 2026
TOPIC: Sodium Hypochlorite Generation, Maintenance, and Equipment
AGENDA TITLE
Agreement with PSI Water Technologies, Inc. for Sodium Hypochlorite Generation,
Maintenance, and Equipment (Specification No. 26-049) (Non-General Fund)
RECOMMENDED ACTION
Authorize the City Manager to execute an agreement with PSI Water Technologies, Inc.
to provide sodium hypochlorite generation, maintenance, and equipment in an amount
beginning July 21, 2026, and expiring July 20, 2027, with an estimated annual budget of
$500,000 with provisions for four, one-year extensions, in a total amount not to exceed
$2,500,000 (Agreement No. A-2026-XXX).
GOVERNMENT CODE §84308 APPLIES: No
DISCUSSION
The Public Works Agency (PWA) is responsible for the daily operations of the City's
drinking water system. The water system comprises of approximately 480 miles of water
main, 21 groundwater wells, seven pump stations, 10 reservoirs with a storage capacity
of 45 million gallons, four pressure-regulating stations, and seven connection points to
the Metropolitan Water District (MWD). The system has an average daily demand of 43
million gallons from its roughly 45,000 service connections.
To maintain compliance with federal and state drinking water regulations, the City uses
sodium hypochlorite generation (SHG) units to produce chlorine for potable water
treatment. The SHG units utilized by the City meet the water quality requirements
established under the City's Domestic Water Supply permit and are essential for
maintaining regulatory compliance; therefore, their ongoing maintenance and reliability
are critical to water distribution operations. In addition, this form of sodium hypochlorite
generation is recognized as one of the safest methods for introducing chlorine into a
potable water system, providing safe and reliable drinking water to residents. These
systems require specialized preventive maintenance, system calibration, replacement of
proprietary components, and emergency repair services to ensure uninterrupted
operation.

Invitation for Bids (IFB) No. 26-049 was advertised on April 9, 2026 on the City's online

2 Santa Ana vendors notified
9 Vendors downloaded the bid packet
1 Responsive bid received
0 Responsive bids received from Santa Ana vendor
Bids were solicited, opened on May 5, 2026, and evaluated (Exhibit 1). One bid was

similar maintenance and support services to Rancho California Water District, Los
Angeles Department of Water and Power, and Irvine Ranch Water District. Award of the
agreement ensures the continued reliability and operational performance of the City's
SHG systems, including routine maintenance, emergency repairs, and system
upgrades, and has the capability to provide prompt maintenance services, emergency
repairs, and system upgrades.
