8/9/2007: Cost Savings Realized with TPE-R Waterstop on ROBERT A SKINNER WTP OXIDATION RETROFIT

Winchester, CA - The Metropolitan Water District of Southern California has undertaken a Oxidation Retrofit Program at the Robert A. Skinner Plant in Winchester, CA to enable the district to continue meeting new and improved state and federal drinking water regulations. TPE-R material provides Ozone resistance comparable to stainless steel and is much easier to install, making TPE-R the material of choice for Ozone Contactor structures such as this. TPE-R waterstop utilizes the same simple heat welded splicing process of PVC and eliminates the need for high cost certified welding equipment and labor required for Stainless Steel. Further, 50-foot coils of TPE-R versus 10-foot lengths of stainless steel drastically reduce the number of splices required. TPE-R is also flexible enough to radius around corners in vertical installations, eliminating the need for some welded corners. Where complicated welds were necessary, Westec was able to factory-fabricate fittings for the contractor, providing them with assured quality and further cost savings. This recent MWD Ozone Retrofit comes on the heels of another previous upgrade at the Joseph Jensen WTP, which also utilized Westec TPE-R Waterstop.
