Commercial Water Treatment in Fresno, CA
Fresno is the heart of the Central Valley's food economy. Packing houses, processors, cold storage and the hospitals and campuses around them all depend on cooling towers, boilers and refrigeration that can't quit in a 105-degree July. Hydrovida helps Fresno facilities cut water and energy costs, keep equipment clean and stay within discharge permits.

What's in Fresno's water
The City of Fresno's water comes from about 260 wells across the city plus three surface water treatment facilities. The city has been shifting more of its supply to treated surface water to protect the groundwater basin, so the mix you get depends on where you are and the time of year.
Fresno's 2025 water quality report lists system-wide hardness of 87 to 150 mg/L, averaging 129 mg/L, or about 7.5 grains per gallon, with dissolved solids averaging about 187 mg/L. That's moderate, but it's not the same at every site or season. A tower or boiler program set once and left alone will either waste water or start to scale or corrode when the source changes.
Who we work with in Fresno
Fresno's industrial base is built on agriculture: fruit, nut and vegetable packing and processing, dairy and beverage plants, cold storage and refrigerated distribution. Packing and cold storage run ammonia refrigeration with evaporative condensers and hydrocoolers through harvest. Processors run boilers for steam and sanitation. Hospitals, universities and offices run central plants with cooling towers and closed loops. We already work with facilities across California.
How Hydrovida fixes it
For cooling towers and evaporative condensers, we test your water, set inhibitor and cycles for the supply you actually get, and install controllers with remote monitoring so treatment keeps up when the source changes. For refrigeration condensers and hydrocoolers, clean heat transfer means less power and more reliable product cooling. For boilers, we protect tubes and cut blowdown, fuel and downtime during peak season.
For processors with high-strength wash water, we help improve discharge quality and lower sewer surcharges. For hospitals and any building 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.
Local programs and discharge rules
The City of Fresno's Water Conservation Program offers free water-use surveys for businesses, and its rebates focus on fixtures and landscaping rather than cooling towers. The biggest savings for most plants come from running towers, condensers and boilers at the right cycles.
The city's Wastewater Management Division regulates industrial discharges to the Fresno-Clovis Regional Wastewater Reclamation Facility through its pretreatment program. Businesses that discharge process wastewater may need a wastewater discharge permit. We help you keep blowdown and process discharge within your limits.

Questions
How hard is Fresno's water?
Fresno's 2025 water quality report lists system-wide hardness of 87 to 150 mg/L, averaging 129 mg/L, or about 7.5 grains per gallon. It varies with the mix of well and surface water.
Do you work with packing houses and cold storage?
Yes. We treat cooling towers, evaporative condensers, hydrocoolers and boilers for food processing and refrigerated storage.
Does Fresno require a discharge permit for process water?
Businesses that discharge process wastewater should check with Fresno's Wastewater Management Division, which issues permits under the pretreatment program.
Can you help during harvest season?
Yes. We plan treatment and service around your peak season, so towers, condensers and boilers stay clean when downtime costs the most. Remote monitoring helps catch problems early.
