Commercial Water Treatment in Corona, CA
Corona is one of the Inland Empire's busiest manufacturing and distribution hubs, and its water changes with the season. When the blend shifts, cooling towers, boilers and process water systems can drift out of control. Hydrovida helps Corona facilities cut water and energy costs, stop scale and corrosion, and keep discharge in check.

What's in Corona's water
The City of Corona Utilities Department reports that in 2025 about 45.5% of its water came from city-owned wells, 49.6% from the Colorado River and 4.9% from the State Water Project. The surface water is treated at the city's Sierra Del Oro and Lester plants. Most of the groundwater goes through the Temescal Desalter, a reverse osmosis plant, and is then blended with other sources at five blending facilities.
Those sources are very different. Corona's 2025 report lists hardness of about 88 mg/L for State Water Project water, 288 mg/L for Colorado River water and up to 452 mg/L for some groundwater, with treated system water averaging 146 mg/L, or about 8.5 grains per gallon. The city notes that hardness varies with demand and season. A cooling tower or boiler program set for one blend can scale up or turn corrosive when the blend changes, so it needs testing and control that keep up.
Who we work with in Corona
Corona's industrial areas host food and beverage manufacturing, building products and fabricated metal plants, electronics and medical device makers, and large distribution warehouses along the 91 and 15. Plants run process cooling towers, boilers and RO systems. Warehouses and offices run comfort cooling and closed loops. Many also have wash-down or process discharge that falls under the city's industrial user rules. We already work with facilities across Southern California, including the Inland Empire.
How Hydrovida fixes it
For cooling towers, we test your water, set inhibitor and cycles of concentration for Corona's changing blend, and install controllers with remote monitoring so conductivity and chemical feed adjust instead of drifting. For boilers, we pair softening and treatment to protect tubes and cut blowdown and fuel. For RO and process water, we keep membranes running longer with the right pretreatment and antiscalant, and our lab can autopsy a failed membrane to find the cause.
For any site with a cooling tower, we write and maintain ASHRAE 188 water management plans and run routine Legionella testing. Our chemistry is made by Hydrovida, with NSF/ANSI/CAN 60 certified chemistry options available.
Rebates and discharge rules
The City of Corona's business rebate page lists SoCal Water$mart rebates for cooling tower conductivity controllers and cooling tower pH controllers, and Corona and Western Municipal Water District add funding for some devices. Rebates must be reserved before purchase and amounts can change, so we help you confirm eligibility before you buy.
Corona's Utilities Department requires industrial users to apply for a discharge permit, and new users must apply at least 90 days before they start discharging. We help you keep blowdown and process discharge within your limits and your records ready.
