ADEQs Engineering Review team reviews subdivision applications for adequate water facilities, sewage disposal systems, and garbage collection and disposal services. 

Sewage collection systems comprise pipelines, manholes, pumping stations, force mains, and all other structures and devices that collect and transport sewer from residential, commercial and industrial buildings to a sewage treatment facility or to an onsite wastewater treatment facility.

An onsite wastewater treatment facility refers to a conventional septic tank system or alternative system installed at a site to treat and dispose of wastewater, predominantly of human origin, generated at that site | Learn More >

ADEQ only reviews public and semi-public swimming pools and spas. ADEQ does not review the plans of residential pools or spas | Learn More >
