City of Prescott Public Works: Airport Trunk Main Phase 2B

The City of Prescott and their contractor, Fann Contracting, Inc. are currently working on a utility upgrade project. The project will replace approximately 15,600 lindeal feet of 24-inch pipe with 48-inch gravity-fed sewer trunk mains highlighted in the map below.

This project is one of several projects that will complete the centralization of the wastewater treatment process. Centralization, when completed, will combine all wastewater treatment processes at the Airport Water Reclamation Facility and decommission the Sundog Wastewater Treatment Plant. This phase of the project is scheduled to be complete in spring 2021.


Crews will continue performing boring operations under Highway 89A, just southeast of Larry Caldwell Drive. In addition to this work, crews will continue installing new manholes and sewer main as highlighted on the map below.

Monday through Friday, February 3 to February 28, 7 a.m. – 7 p.m.
Please be aware of large trucks and heavy equipment accessing the work zones.
