Phoenix & Maricopa County, AZ Backflow & Grease Trap FAQs

Direct answers sourced from City of Phoenix Water Services & Planning & Development (P&D) — Backflow Prevention Program and City of Phoenix Water Services Department — Environmental Services Division (ESD) regulations.

How are annual backflow test reports submitted to the City of Phoenix in 2026?

Unlike suburbs that charge third-party portal fees, the City of Phoenix accepts original, signed City of Phoenix Backflow Prevention Assembly Test Reports directly by email at Backflow.Prevention@phoenix.gov (or by mail to 438 W. Adams St., Phoenix, AZ 85003) at $0 cost. The test must be performed by a company on the active City of Phoenix Approved Backflow Tester Company List using a gauge calibrated within the last 12 months, and customers must keep copies of test records for at least 3 years.

What happens if I miss my City of Phoenix backflow test due date?

Under Phoenix City Code Chapter 37, Section 37-146, failure to test, repair, or submit records for a required backflow assembly can result in termination of water service after 10 days written notice (or immediate termination without prior notice if the Water Services Director determines a public health hazard exists). In addition, the City may impose a civil penalty of up to 1,000% (10x) per billing period on all water charges from the date corrective action was required until compliance is achieved.

What is the required grease trap and interceptor pumping schedule for Phoenix restaurants?

Under Phoenix City Code Chapter 28 (Sections 28-12 through 28-15) and the Water Services Department Environmental Services Division (ESD) FOG BMP Manual, indoor hydromechanical grease traps (permitted for up to 4 fixtures with no dishwasher or disposal) must be completely pumped and cleaned every 30 days and never exceed 90 days. Outdoor gravity grease interceptors (required for >4 fixtures or any dishwasher/garbage disposal; minimum 500 gallons) must be pumped 100% empty at least every 3 months (90 days) or whenever floating FOG and bottom solids exceed 25% of capacity.
