Costa Mesa's water supply and your plumbing
Mesa Water District serves its customers 100% local groundwater, with no imported water: about 85% from shallower wells in the Orange County Groundwater Basin and 15% amber-tinted water from a deep aquifer. [1]
The amber color comes from remnants of ancient redwood forests and is removed at the Mesa Water Reliability Facility with sand separators, cartridge filters and nanofiltration membranes. [2]
Costa Mesa plumbing questions
Should old pipes in a Costa Mesa home be repaired or replaced?
One leak in otherwise sound pipe is usually repaired; when galvanized or failing pipe leaks in several places, repiping costs less over time. Why it comes up in Costa Mesa: 1950s–60s homes still carry galvanized pipe.
When is a leaking water heater an emergency in Costa Mesa?
A leak from the tank itself won't stop and usually means replacement; turn off the gas or power and the cold-water valve, then call. Why it comes up in Costa Mesa: Hard groundwater scales tanks.
Is Costa Mesa water imported?
Not for Mesa Water customers: it is 100% local groundwater, including treated amber water from a deep aquifer.
What is amber water in Costa Mesa?
Groundwater tinted by ancient redwood remains; Mesa Water removes the color with nanofiltration before delivery.
Is all of Costa Mesa served by Mesa Water?
Most is; some areas are served by Irvine Ranch Water District. Your bill names your provider.
Should I repipe an Eastside Costa Mesa home?
Many 1950s homes still have galvanized pipe; low pressure and rusty water mean it's time.
