The City of West Sacramento project involved constructing a new water transmission main which tied into an existing 36" water line and helped bring a greater volume of water to a new residential area that the City was developing. The job involved installing both 24" and 36" Concrete Cylinder Pipe, a cathodic protection system, blowoffs, manholes, tapping sleeves and a series of 24" and 36" gate valves and butterfly valves. The total length of the system was 11,000 LF. 8, 000 LF of this system were installed using the open cut trench method with depths varying from 8 ft to 20 ft and about 500 ft was installed using an aerial crossing, that was installed on a bridge which crossed over a ship channel. The remaining 2,500 ft of pipe was installed using the trenchless method (microtunneling). Nada Pacific Corporation out of Caruthers, California performed the microtunneling. The microtunneling portion was broken down in two phases. The first phase involved a 2,000 ft stretch of tunnel, which went directly under Interstate 80 and the second phase involved a 500 ft stretch of tunnel, which went directly under a Union Pacific rail line. While the open cut installation was in progress a great deal of traffic control was required. A majority of the traffic control involved traffic diversions using k-rail, channelizers, traffic cones, electronic message boards and fabric traffic signs. Lastly, some of the minor work on this job included compacting, laying pipe bedding, backfilling, removing existing pavement, trench paving, traffic loop repair and replacing reflective pavement markers/reflective pavement striping.
