Pipe Size

500’ of Permalok®  T-7 10’ lengths, pressure tested to 90 PS

The Problem

The project required microtunneling 183-foot shaft into Lake Nacimiento with a hot lake tap.

The Solution

Construction of this unique project included a 180-foot deep shaft penetrating a variety of challenging ground conditions including sandstone and fractured geology. The design of the project called for the installation of a precast transition structure and the installation of several hundred yards of underwater structural concrete, multiple precast piling and more than 500 lineal feet of Permalok®  10’ lengths pressure tested to 90 PSI, intake screens and pipeline contracts.
