Background
The city of San Luis AZ has two separate Water Distribution Systems (WDS). The Central WDS with a capacity of 4 million gallons per day (MGD), and the East Mesa system with 3 MGD capacity. The Central system operated at full capacity during the summer time, while, the East Mesa system was underutilized.
Description
Achieve proper drinking water service reliability for the city of San Luis, AZ, through the interconnection of two existing main systems by a new PVC water main, in order to avoid incidents of low pressure and/or service interruption, contributing to the reduction of the risks associated with waterborne diseases.
Benefits
The Project consisted of the installation of a new 16 inch diameter PVC water pipeline to interconnect the two WDS. The new pipeline provided bidirectional flow of drinking water, improving the operation capacity of the city’s water supply systems to meet daily peak demand during the summer season, especially in the Central WDS.
