 This section provides details on how to submit an application for an Approval to Construct and an Approval of Construction for Drinking Water Treatment and Distribution Systems. An Approval to Construct is a certificate that allows an applicant to construct a public water distribution system, and an Approval of Construction is a certificate that allows an applicant to operate a public water distribution system after construction and final testing have been completed.
A public water system is a water system that provides water for human consumption through pipes or other constructed conveyances, and has at least fifteen service connections or regularly serves an average of at least twenty-five persons daily for at least sixty days a year. Water system facilities comprise of pipelines, pumping stations, force mains, storage tanks, wells, and all other structures and devices that collect, treat, and deliver drinking water to residential, commercial and industrial buildings. The approval of the installation of Public water systems is conducted under the Safe Drinking Water Act (SDWA), and is administered by the Engineering Review (ER) Program of the Safe Drinking Water Section.
ADEQ Form 222 is the Completeness Review Guide for Engineering Review that provides a quick overview of the requirements for application submittals for Subdivisions, Sewage Collection Systems, Water Treatment and Distribution Systems and On-site Wastewater (Septic) Treatment Facilities. In addition, applicant must consult the Delegation Agreement Matrix to determine where the application must be submitted.
