Recommendation:

It is recommended that the City Council of the City of Calexico approve the following:

1. Authorize City Manager to Issue Purchase Order to Veolia WTS Services, USA, Inc. in the amount of $603,235.00 for the rental of three (3) mobile clarifiers during the Rehabilitation of Clarifier "B" and "C" Project at Water Treatment Plant.

Background:

On June 4, 2025, the City Council of the City of Calexico authorized the Interim City Manager to sign Master Services Agreement with Utility Services Co., Inc. for the Rehabilitation of Clarifier "B" and "C" at the Water Treatment Plant.

Clarifiers are integral to both drinking water treatment facilities and wastewater treatment plants.

Clarifiers play a vital role in maintaining public health by effectively removing pathogens and pollutants from raw water sources. Clarifiers suspend solids and turbidity, clarifiers facilitate the action of downstream treatment processes such as filtration and disinfection, ensuring The City of Calexico Water Treatment Plant currently has two (2) clarifiers:
• Clarifier "B"
• 4.2 Million Gallons per Day (MGD)
• 55-foot diameter clarifier
• Built in 1968
• Clarifier "C"
• 10.0 Million Gallon per Day (MGD)
• 80-foot diameter clarifier.
• Built in 1998 and rebuild in 2010 due to April 4, 2010 earthquake Discussion and Analysis:

Utility Services Co., Inc. is ready to begin working on Clarifier "B." Once Clarifier "B" is complete and operational, Utility Services Co., Inc. will begin working on Clarifier "C." Since Clarifier "B" has a capacity of 4.2 million gallons per day (MGD) and Clarifier "C" has a capacity of 10 MGD, the City will need to rent three (3) mobile clarifiers to meet the City's current water demand. City staff obtained a price quote from Veolia WTS Services USA, Inc in order to provide an additional 3.456 MGD during construction.

After reviewing Veolia WTS Services USA, Inc. proposal, City staff is recommending to proceed with issuing a purchase order in the amount of $603,235.00 for the rental of three (3) mobile clarifiers for the Water Treatment Plant.

Fiscal Impact:

Capital Improvement Program Budgeted Item for FY 2025-2026 Fund No. 516-91-942-56003-000 $603,235.00
Total $603,235.00

2.3 Influent Water Flow Data
Flow rate, pressure and temperature required at inlet to the equipment.

Mobile UF (MPAK-80)
Minimum Maximum
400 890
Inlet Flow Rate (gpm)
Pressure (psi) * 15 90
Temperature ("F) 40 90
Pretreatment used (if any) | N/A (Surface Water)
* Pressure must be measured under flowing conditions at the inlet to the Veolia equipment.

2.4 Product Water Qualiiy and Flow Data
The following performance parameters are expected upon equipment start-up, based on the data listed in the influent quality table and design sections above.

Maximum Flow Rate per unit, gpm / Up to 800 GPM
The Veolia system should have similar effluent quality TSS as the customer's clarifier system with proper system operation at a maximum flow of 800 gpm, and influent quality consistent with the defined influent window.

TOC associated with TSS may be removed through the Veolia system. The Veolia system will not use powdered activated carbon (PAC) to remove additional TOC.

2.5 Influent Water Variability
In the event that the influent water exceeds the specifications used in engineering this proposal or the water source changes, the ability of the water treatment system to produce the designed treated water quality and/or quantity may be impaired. If influent water is provided to the system, which does not meet the specifications shown above, and the equipment therefore does not meet the listed product water characteristics, the total value of the contract shall be paid in full as described in this proposal. Veolia shall endeavor to restore the full product water quality as soon as possible after the influent conditions have been restored. Any additional costs incurred by Veolia resulting from a change in influent conditions, including, but not limited to any repair and replacement of damaged equipment and any additional costs incurred, shall be fully reimbursed to Veolia.

Certain chemicals and system components proposed for use in this application are certified to NSF/ANSI/CAN standards - references are available upon request.

The proposed systems) are not NSF certified but certain wetted components may be. Veolia WTS will guarantee meeting treated water quality as specified in Section 2.4 only, provided that the fluent water quality meets the specifications provided in Section 2.2. It is the Customer sponsibility to determine whether the treated water is of adequate quality for their intended us Veolia Confidential and Proprietary Information

2.6 Operational Basis
Percentage | 90-95%
Down time for routine maintenance such as membrane cleaning, cartridge filter change outs, and pump maintenance must be allowed. All planned maintenance outages will be discussed with the site. They will be scheduled to have minimal impact on site requirements.

2.7 Wastewater Streams
The following streams are waste lines that will derive from the proposed equipment. The customer must dispose of all these streams and provide the required connections to drain as specified in Customer Scope of Supply section. Connection details of each line can be found in the Veolia Scope of Supply section where the specification for each supplied unit is detailed.

2.9 Preservative Chemicals
Prior to shipment, the UF modules are filled with a preservative solution of 50% glycerin that protects the membrane fibers until they are ready for use. After the modules have been installed, this solution must be completely flushed from the modules before production can begin. The flushing procedure will create a byproduct permeate with a high TOC content that is unsuitable for normal discharge into the environment (example: down a drain connected to a municipal sewer system). As a result, when flushing a newly installed module, direct all permeate to a suitable container that can then be sent for proper UF membranes that are to be taken offline for longer than two days must be preserved in order to prevent biological growth within the modules. For storage periods of up to approximately 1 week, filling the modules with water containing sodium hypochlorite at a minimum residual concentration of 1-2 mg/L is adequate (modules have a maximum chlorine tolerance of 1,000 mg/L). For storage periods longer than 1 week, a residual sodium hypochlorite concentration of 15 mg/L. is required.

2.10 Equipment Availability
Veolia requires a two (2) week period notice from a technically and commercially clean order acceptance in order to prepare the equipment proposed in the Veolia Scope of Supply section prior to dispatching it to the Customer site. We will however endeavor to expedite this. For best projection of equipment availability in the fall/winter months, a purchase order now is recommended to secure equipment.
