Water Main Replacement on Crawford Street in Nogales, Arizona

Status: Completed Construction

Background

Water and wastewater collection services are provided by the City through its Public Works Department. Currently, the City has two separate well field sources (WFS) to provide water services. The Santa Cruz River WFS is located northeast of the city and has six well sites that
conveys water via a 16-inch transmission line to the Royal Road Tank (a 1-million-gallon reservoir) and the Crawford Tank (a 2-million-gallon reservoir). Potrero Creek supports the other WFS, supplying three well sites that convey water via a 16-inch transmission line to the North, High School, and West Hill Tanks (each with a 1-million-gallon reservoir).

The existing water main on Crawford Street consists of a 4-inch cast iron pipe with lead fittings and a 6-inch cement asbestos pipe, which were installed in 1918. It is a shallow main that has experienced breaks over the last few decades, as well as service line repairs and replacements. Breaks are now occurring more frequently, causing frequent water losses
and interrupting service, which lends to a potential for water quality and public safety issues.

Description

The project consists of the replacement of the Crawford Street water
distribution main, which includes the following components:

  • 2,967 linear feet of 8-inch PVC water main
  • 15 linear feet of 8-inch ductile iron water main
  • Replacement of 49 water connections and flow meters
  • 4 combination air release valves
  • 24 gate valves
  • 7 fire hydrants

Benefits

The project will provide access to safe and reliable drinking water services, directly benefiting 330 residential connections, as well as eliminate service interruptions and reduce water losses.
