What's in Santa Ana's water

The City of Santa Ana's 2025 water quality report says the city's water was 85% groundwater from the Orange County Groundwater Basin and 15% imported water from the Metropolitan Water District. That makes Santa Ana's water mostly local and fairly consistent.

It's also hard. The report lists groundwater hardness averaging 239 mg/L, or about 14 grains per gallon, with a range of 130 to 307 mg/L, and imported water at about the same level. Water that hard scales tower fill, chiller tubes, boilers and heat exchangers quickly. It also means softeners and RO pretreatment have to be sized and maintained properly. Many towers run at low cycles to avoid scale and end up buying and discharging more water than they need to.

Who we work with in Santa Ana

Santa Ana's industrial areas include aerospace and defense suppliers, electronics and metal finishing, food and beverage manufacturing, and printing and packaging, along with hospitals, county and federal buildings, schools and office towers downtown. Plants run process cooling towers, boilers and RO. Hospitals and government buildings run central plants and need documented Legionella control. We already work with facilities across Southern California.

How Hydrovida fixes it

For cooling towers, we test your water, set inhibitor and antiscalant for Santa Ana's hard groundwater and raise cycles safely, with controllers and remote monitoring between visits. When towers are already scaled, we clean them and keep them clean. For boilers, we test, service or replace softeners and protect tubes. For RO and process water, we keep membranes running longer with the right pretreatment.

For hospitals, government buildings and 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

Santa Ana is in Metropolitan's service area, and the city points businesses to SoCal Water$mart, which lists rebates for cooling tower conductivity controllers and pH controllers. Rebates must be reserved before purchase and amounts can change, so we help you confirm eligibility first.

Industrial discharges in Santa Ana fall under OC San's source control program, which issues Class I and Class II industrial wastewater discharge permits based on what and how much you discharge. We help you keep blowdown and process discharge within your limits.
