CHALLENGE: Prioritizing Water System Improvements with Limited Resources, Mountainaire, AZ
CLIENT: Ponderosa Utility Corporation, Arizona
PROJECT: Mountainaire asset management based water distribution system study to assist with prioritizing water system improvements
THE CHALLENGE: Mountainaire is a small water distribution system with limited manpower and revenue resources, and the operation and maintenance of the system is often reactive rather than proactive.
We successfully helped secure WIFA funding for the completion of the study which provides guidance to the PUC on how the system operates, what improvements are needed for efficient operation and continued maintenance of the system, and a prioritized approach to assist in funding and implementation of projects. This asset management based water distribution system study addresses undersized deteriorating water mains, above grade assets, and the energy efficiency of the pumping system. The study evaluates the system as a whole, based on above grade and below grade assets. Above grade assets are evaluated based on remaining useful life expectancy. Water mains are based on hydraulic capacity, criticality, and risk of failure. A hydraulic model was created for the study.
PROGRESS: Using the findings of the study, we are currently providing engineering services to evaluate flow and pressure requirements for the existing Kiowa Site booster pump station in order to construct a constant pressure pumping system to replace the existing booster pump and hydropnematic tank system that is old and failing.
