Deionized Water Filtration System Maintenance

The San Mateo County Sheriff's Office is seeking a qualified manufacturer or authorized service provider to perform biannual preventative maintenance for the Millipore Elix 20 and Milli-Q Advantage A10 water purification systems at its Forensic Laboratory in San Mateo, California. The scope of work includes general inspections, the replacement of routine maintenance components using only OEM parts, and the verification of water-quality monitoring instrumentation to ensure systems meet manufacturer specifications. Maintenance is scheduled for November 2026 and May 2027. As a unique requirement for the forensic environment, the contractor must provide a DNA reference sample via a buccal swab to identify potential contamination. The contract will have an initial term of one year, with two optional one-year extensions at the County's discretion. Proposals are due by September 28, 2026, and must be submitted via the eProcurement portal. Awarding will be based on the overall best value, with evaluation weighted toward minimum qualifications (58%) and price (29%). To qualify, proposers must demonstrate at least four years of similar service experience within the last seven years and employ technicians trained in Millipore and Milli-Q systems. Preference points are available for local, small, and micro businesses or non-profits, with a specific tie-breaking advantage given to local entities.
