f <br /> A <br /> right to talo an easement and IVIS-. Singer responded that developers likely granted easements40- <br /> 50 <br /> years ago. <br /> Chairman Fudala noted that the design provided some excess capacity. Mr. Lyons inquired <br /> about the alternating pumps at C5 and Mr. Kuchar confirmed that the pumps would alternate. <br /> Mr. Dons recommended that a sure pump be readily accessible on site in the event that one o <br /> the pipes failed. Chairman Fudala noted that there may be storage available at the high school <br /> treatment plant, adding that the contractor running the plant would be inspecting and maintaining <br /> the pump station. It was noted that the applicant would be providing $20,000 for any <br /> modifications to the plan. Mr. Kuchar stated that if one pump failed, the other pump would run <br /> and storage would be unnecessary but indicated that he would look into another pump. Mr. <br /> O'Hara inquired about the life expectancy of the pump and Mr. Kuchar responded that he <br /> believed it to be 10-15 years. Mr. Marcell i. inquired about the location of the 4 inch main and <br /> whether it was on school property. Chairman Fudala responded that it was now town property <br /> and the sewer line would be for municipal purposes and would not require a vote from Town <br /> Meeting. fir.-o"Hara referenced the Zoo gallon per niinute pump capacity for 16 units and <br /> inquired about the total number of units that could be accommodated. Mr. Lyons responded that <br /> the capacity would be close to 3 tunes.- Mr. Kuchar added that the system was designed for. <br /> 4,400 gallons per day of nova and that the actual flow would be significantly less. Mr. O'Hara <br /> inquired whether another length of pipe should he laid since the road would he excavated but <br /> Chairman Fudala stated that it would not work with the flow. <br /> Mr. Lyons made a motion to approve the Breezy Acres sewage lift station and force main <br /> on the plan revision dated March 8, 2011.

Mr. Docherty reported that AIRvAC was based in Rochester, Indiana and that <br /> vacuum sewers were located in many states and locations throughout the world. Mr. Docherty <br /> described the vacuum system as modular with a lift station and vacuum pumps added to it. <br /> Vacuum sewers have been considered because they offer cost savings over gravity suer <br /> systems. Mr. Docherty noted that the vadum suer would not be used everywhere, such as on a <br /> hill which would be better suited for a gravity system, vacuum sewers feature back-up <br /> -generators, which would be the only electrical connection, but will provide back-up sewer <br /> service. <br /> Mr. Docherty stated that three main components existed in the vacuum sewer system to include <br /> the valve pit package, the collection piping system and the vacuum station. The valve pit <br /> package is the connection between the hone and the vacuum sewer main. W. Docherty <br /> described the process by which the flow travels through a sump and'how the valve pit package <br /> functions. Chairman Fudala inquired about the life of a valve and lith. Docherty responded that <br />
