CS-Xpress ™

This patented solution is used to reduce CSO frequency and volume. The novel technique eliminates bottlenecks by significantly increasing the hydraulic capacity of the sewer (vs. its gravity-flow capacity) during wet weather events.

As an alternative to parallel relief sewers and/or deep tunnels, this approach is much less costly and much less disruptive for the densely-developed older cities which rely on combined sewer systems. More Information


This patented vacuum sewerage system handles flow inputs much greater than "conventional" vacuum systems. It can be designed to operate as stand-alone or in combination with AIRVAC or Roediger vacuum systems.

The HILIFT feature is useful for source separation in commercial or industrial applications. More Information



This patented onsite wastewater system is an alternative to the elevated sand mound. It can be used to transform "unbuildable" or other restrictive situations into valuable buildable property. More Information
