Cotati City Council
Agenda Staff Report
Item type: CONSENT CALENDAR (ACTION)
To: City Council
Subject: Well 1A Treatment System and Controller Repairs and Replacements Date: January 24, 2023
Written by: Craig Scott, Director of Public Works/City Engineer Recommendation
It is recommended that the City of Cotati City Council approve by motion, service agreements with Telstar Instruments for replacing components of the chlorine generating system and replace the controller, including programming at municipal Well 1A.
Background
The City owns and operates a public water system which is regulated by the State Water Quality Control Board, Division of Drinking Water. The water system consists of three (3) municipal wells and two (2) connections to the Sonoma Water regional water transmission system. For proper operation and maintenance, the City is required to pro-actively replace aging system components.
Analysis/Discussion
The City’s 5-Year Capital Improvement Plan has included the Well 1A/3 Treatment Renewal and Replacement Project in Fiscal Year 2024/25 for an estimated $115,000. The chlorine generation system and Programable Local Controller (PLC) have been in service for 20 years and have exceeded their expected life spans and are subject to failure which would shut down Well 1A.
Staff is recommending replacement now so the well can operate more reliably with the new system when demands ramp up in the summer. City Staff has requested quotes to replace components of the Well 1A chlorine generation system and replace and perform programing for the PLC. Telstar Instruments is uniquely qualified to provide these services as they perform maintenance on these systems for the City.
Financial Considerations
The City is requesting a budget appropriation in the amount of $33,000 to shift this project into fiscal year 22/23. This amount includes the quoted amounts and a contingency of $2,043, in the event there are any unanticipated added expenses upon installation. These funds are to be made available from the Water operations fund, as the primary use is for on going operations and is paid for by utility service fees. To date the Combined Water funds have net inflow of funds of approximately $300,000 and as such this appropriation is not expected to effect the required minimum fund balance.
Environmental Issues
This action is exempt from the California Environmental Quality Act (CEQA) because it is not a project which has a potential for resulting in either a direct physical change in the environment, or a reasonably foreseeable indirect physical change in the environment, pursuant to CEQA Guideline section 15378.
