The Town of Gilbert supplies water and sewer to businesses, runs a cross-connection program that calls for internal backflow assemblies where a line poses a contamination risk, and handles permits through its One Stop Shop. Most commercial calls here are drains, restrooms, water heaters and backflow devices. Call the number on this page to be connected with a local plumber in Gilbert.

How a commercial call works
Start by saying what kind of property it is, what stopped working and whether customers or tenants are affected right now. You'll be connected with an independent local plumber who takes commercial jobs in Gilbert. Expect questions about access, shutoff locations and the hours the building is open, since many businesses want the work done before opening or after close. The plumber looks first, explains the options and the pricing approach, and only then starts.
Cost factors
- Size of the building and how many fixtures or suites are on the affected line
- Diagnostic time: camera inspection, pressure testing or leak locating
- Off-hours work requested to avoid closing
- Patching ceilings, walls or concrete after access cuts
- Permits and inspections through the Town
- Specialty equipment such as commercial water heaters, grease interceptors or backflow assemblies
Gilbert water, sewer and code details
Gilbert treats its own water, blending SRP and CAP canal water with groundwater from 17 Town wells. Its surface water plants use ozonation and chlorination, and chlorine carries through the distribution system. Wastewater goes to the Town's Neely reclamation plant or to the Greenfield plant shared with Mesa and Queen Creek. For a wastewater emergency, call Public Works at 480-503-6400; after hours, use the police non-emergency line at 480-503-6500.
The Town's Backflow Prevention section, part of Development Services inspection and code compliance, requires internal assemblies on supply lines that could contaminate the system, which covers a lot of restaurants, medical offices, car washes and anything with chemical feed. Its inspection specialists are at 480-503-6714 and 480-503-6715. Code and permit questions go to the One Stop Shop at 480-503-6700.
Gilbert's building stock is young: the median year built is 2003, and only about 4 percent of housing units predate 1980. The Town's service line inventory found no known lead or galvanized lines needing replacement. Southwest Gas provides natural gas; if staff smell gas, everyone leaves first, then someone calls 911 and Southwest Gas at 877-860-6020 from a safe spot.
