Description

The City of Ontario is seeking a qualified vendor to provide water deionization (purification) services and ongoing maintenance for its fire‑station and police‑facility vehicle‑wash operations. The contractor will supply, exchange, and service de‑ionized water tanks at eleven fire stations and two police facilities, delivering approximately 1,500 gal of DI water per tank each month, and must respond promptly to any system repairs. Pricing is to be submitted as a lump‑sum, not‑to‑exceed amount with hourly rates for additional labor.

Budget estimate

$20,000 – $60,000

Based on typical costs for DI‑water tank rental ($150‑$250 per 3.6 cu ft tank per month) plus labor ($80‑$120 per hour) and the 13 locations, the annual contract value is likely in the $20,000‑$60,000 range. The lower bound assumes minimal labor and only tank rental; the upper bound includes frequent maintenance, overtime, and higher tank‑rental rates.
