Western Canal Water
Transmission Main: Rural Road to South Water
Treatment Plant
Tempe,
Arizona
Dibble partnered
with the City of Tempe to provide engineering
design and post-design support for the construction
of approximately 10,000 linear feet of new
16-inch and 24-inch water transmission mains.
The pipeline provides transmission infrastructure
linking one City owned well and three SRP
owned wells along the Western Canal between
Rural Road and the finish water reservoir
splitter box located at the South Tempe Water
Treatment Plant (STWTP). The project's numerous
unique features, accelerated delivery schedule
and critical coordination elements were completed
by Dibble in order to deliver a successful
project for the City.
The pipeline was constructed
immediately adjacent to the Western Canal
in right-of-way controlled by SRP. Dibble
worked closely with SRP staff to facilitate
accelerated construction license approval.
Special design considerations for pipe materials,
depth of cover, excavation techniques and
construction sequencing were required to protect
both the pipeline and the existing SRP infrastructure.
The pipeline trench was located as close as
six feet to the south canal bank; while existing
69kV electric was located immediately north
of the alignment.
