Brian Braginton-Smith of The Conservation Consortium, a company <br /> supporting sustainable environmental technologies, represents AIRVAC in the northeast. Mr. <br /> Braginton-Smith described AIRVAC as the world leader in vacuum collection technology and reported <br /> that there are over 300 installations around the U.S. and that it has become the technology of choice for <br /> coastal communities, including Venice, Italy. The technology is a good fit for coastal locations, high <br /> density areas and areas with high groundwater. Mr. Braginton-Smith distributed materials to the <br /> Commissioners. <br /> Mr. Braginton-Smith described the way in which the system operates. Wastewater from the residential <br /> property enters a valve pit and is then pulled by vacuum pressure through a collection system that uses <br /> a sawtooth pattern to allow the gravity to handle a substantial amount of the transfer of the fluid. The <br /> wastewater then flows by differential pressure into the collection tank. When the tank fills to a pre- <br /> designated level, transfer pumps move the wastewater to the treatment facility. The pit is comprised of <br /> a separate top and bottom chamber. The valve activates and controls the discharge of the fluid. Ten <br /> gallons enters the sump and compressed atmospheric pressure triggers the valve which then pulls the <br /> wastewater to the plant. No electricity is needed. Wastewater flows to the plant at 15-1 S feet per <br /> second, preventing blockages. Additionally, operators are never directly in contact with the flow and <br /> the wastewater is stored in a negative storage chamber which is the vacuum storage tank. Mr. <br /> Braginton-Smith described the saw tooth profile as utilizing a series of lifts and negative grade to allow <br /> 1 <br />
