Overview
Everyone that lives in the Valley of the Sun knows how important water is to our daily lives. As desert dwellers, our very existence depends on the availability of water. Therefore, it is not a coincidence that as the Valley grows so does our need for more water.
To help us meet this future need, the city of Phoenix Water Services Department is developing a new water treatment plant project to be built just southeast of Lake Pleasant. The first phase of the Lake Pleasant Water Treatment Plant (LPWTP) became operational in 2007 and will serve the rapidly developing northern areas of Phoenix.
The LPWTP will have an ultimate capacity of 320 mgd with the capability to serve the water needs of about 300,000 households. The planned area it will serve is bounded by Carefree Highway to the south, Seventh Street to the east, and New River Road to the north and east.
The project's plans also call for a raw water pump station and a transmission main from the Waddell Canal, and a finished water transmission main from the LPWTP to the existing distribution system.
The city conducted a study to determine which type of project delivery method should be used for these major facilities. The study determined that the same operator is required for the water treatment plant and the raw water facilities (RWF), so the two project elements were combined. The study also recommended that the city use a Design Build Operate (DBO) delivery method for the Lake Pleasant WTP and RWF and use an optimal Design Bid Build (DBB) delivery method for design and construction of the finished water transmission main.
A series of facilitated workshops (consisting of city staff and consultants specializing in engineering, operations, construction, legal and financial services) will be held during the development phase of the DBO project. The workshops, held monthly over the course of the year, will enable the project team to integrate the different aspects of the project for a smooth progression of work and clear channels of communications.
The vendor solicitation documents consist of the Request for Qualifications and the Request for Proposals. The Request for Qualifications was issued November 16, 2000.
