    Real-Time Collection System Monitoring Is Saving Ratepayers Millions

    A successful pilot program for the San Antonio Water System (SAWS) is expanding to encompass the nation’s widest deployment of smart infrastructure in sewer collection systems. Such technology is lowering operating costs by millions of dollars, reducing pressure on rates, and dramatically decreasing the risk of sewer overflows. The decision reflects a growing trend of using collection system technologies to reduce maintenance and help limit rate increases.

  • Wet Well Wonder In A Deep Sewer Tunnel
    Wet Well Wonder In A Deep Sewer Tunnel

    This wet well is a critical piece of a system designed to intercept wet weather overflows, and it demands powerful, high-quality pumps to handle the load. Designed to reduce environmental impacts resulting from Combined Sewer Overflows (CSOs) in Columbus, Ohio, the Olentangy-Scioto- Interceptor-Sewer Augmentation Relief Sewer (OARS) is the key component in meeting this goal. This sewer tunnel will intercept wet weather overflows that currently empty into the Scioto River and instead carry the flows to the city’s Jackson Pike and Southerly wastewater treatment plants.

Kynar PVDF Jet Aerator For Improved Wear Resistance Kynar PVDF Jet Aerator For Improved Wear Resistance

Ten years ago, KLa Systems was presented with the challenge of finding a more wear-resistant material for our jet aeration nozzles.  The inner nozzle is the liquid propulsion nozzle of the jet aerator and continuously sees high volumes of motive liquid flow at velocities ranging from 33-46 ft/s.  Traditionally, these inner jet nozzles were made from the same FRP material as the outer jet with the industry accepted corrosion/abrasion liner made up of C-Glass/Nexus and Silicon Carbide impregnated into the vinylester resin.  For many years this material had held up in most industrial and municipal bioprocesses with no adverse deterioration or wear.
