Over the past 20 years or so, sewer lift stations across Southern California have been working tirelessly to keep up with the ever-increasing demand as more and more housing is being built. Today, the older and smaller neighborhood pump stations that have long been neglected are being replaced or updated to handle the increased effluent that is being pumped and to repair the damage that has occurred over the past 20 plus years.

During the past 20-plus years, the sewer bypass equipment and methods of installation have undergone a steady evolution; today, automatically controlled pumps are the trend. This technology has been with us for quite a while; however, it is very costly. With most bypass work being of rather short duration, past projects have not warranted the expense of this type of technology. Olsson Construction Inc., has two such projects that are each nearly a full year in duration. The requirements for automatic controlled pumps and 100 percent backup make these projects very interesting, as studies of where the future of bypass pumping is heading.
