Legend’s Clubhouse & Restaurant owners were spending over $15,000 per year in extensive pumping of their grease trap and septic tanks and jeopardizing the expensive mounds with the grease that was getting out to them.   Greg was pw-Clubhouse-copy_A1Aable to design a system at a construction cost of $25,000 for a two year payback in savings on the pumping costs alone.  The owner is now enjoying a substantial yearly savings, the system has paid for itself, and the longevity of the mounds is greatly enhanced.
