Report
Summary
The purpose of this project is for the City of Phoenix to treat Colorado River water at the Union Hills and Lake Pleasant WTPs, which supply water to north Phoenix. The Water Services Department determined that the areas served by these two WTPs could be impacted should Colorado River water restrictions occur and that several major upgrades to the water system are necessary to avoid this outcome. The improvements will ensure reliable water transmission from the 24th Street WTP and Deer Valley WTP to north Phoenix.
The Zone 3D and 4A Improvements Program is broken into the following packages and segments:
WTP BPSs
- Package 1: 60 Million Gallons per Day (MGD) BPS and Pressure Reducing Valve (PRV) Station at 24th Street WTP.
- Package 2: Three WTP BPSs, between 40 and 65 MGD each, and a 20 MGD PRV Station at Deer Valley WTP.
Remote Facilities BPSs
- Package 3: 60 MGD BPS and PRV Station at Central Avenue and Deer Valley Road.
- Package 4: 60 MGD BPS at 32nd Street and Bell Road.
Water Transmission Mains
- Segment 1: Large water transmission mains from 24th Street WTP to 32nd Street and Shea Boulevard.
- Segment 2: Large water transmission mains from 32nd Street and Shea Boulevard to 32nd Street and Bell Road.
- Segment 3: Large water transmission mains along 35th Avenue from Thunderbird Road to Grovers Avenue.
Wilson's and Carollo's services include, but are not limited to: performing design work; coordinating potholing; attending meetings; conducting workshops; reviewing Guaranteed Maximum Price (GMP) proposals, project schedules, construction bid price and subcontractor selection plans; and providing land survey, surge analysis, and site geotechnical investigation services, as needed.
