Underground utilities construction is nearing completion for the $8.7 million family entertainment zone (FEZ) infrastructure improvement project west of Costco along the 120 Bypass.
The project is being paid for with redevelopment agency bond receipts. It is part of the effort to secure a 60-acre waterpark resort, 500-room hotel, and conference center and developing a complementary entertainment zone.
Both the new sewer and water mains at the FEZ have been installed and are undergoing final testing. Once the testing and punch list items are complete the lines will be put into operation.
The new 48-inch reinforced concrete pipe (RCP) sewer main is lined with T-Lock technology. T-Lock is a PVC liner to protect the RCP from corrosion. The combination of strength from the reinforced concrete with the corrosion protection from the PVC liner should provide a long lasting facility that will serve all of south Manteca for many years. The sewer main has been connected at the Atherton and wastewater treatment plant tie-in locations. The new 18-inch water main and the tie-in at Daniels Street have also been installed.
The new sewer and water mains were both installed by micro-tunneling under the 120 Bypass. Micro-tunneling is a trenchless tunneling technology that achieves installation with only two excavations at each end of the alignment. Micro-tunneling uses a remotely controlled boring machine to drill through the soil while a casing pipe is jacked into place behind the boring machine. Micro-tunneling allows the installation of pipes underneath natural and well as man-made obstacles such as highways.
The project is on schedule and anticipated to be completed by September 2017.
