main installment cost but excludes the cost of developing a detailed engineering plan. The <br /> Robert B. Our Corporation provided the installed cost of placing it in the road with repaving. <br /> The cost estimate totaled $85,,626,700. <br /> Mr. Quann referenced the Back Road Site and highlighted the various branches. An analysis <br /> was completed for each site and was based on the topography of the land- The Back Road Site <br /> was comprised of 440 housing units and the wastewater would be transported to the Back Road <br /> Treatment Site. Mr. Quann stated that total dynamic head was the total equivalent height that <br /> fluid would be pumped, taking into account friction losses in the pipe. The total dynamic head <br /> for the Back Road Site was 118 feet, which was well within the operator range of the pump,of <br /> 185 feet continuous. The cost per connection would total $16,615.34 and included the collapse <br /> of the septic. The estimated cost for the site totaled $7,277,520.02. Estimates were based on <br /> using HDP pipe, but SDR 21 PVC could also be used. Mr. Quann noted that 10°/o contractor <br /> overhead and 10% contingencies were included in the cost estimates for the purposes of <br /> planning. <br /> Regarding the Heritage Park Site, Mr. Quann r- ported that here were a variety of lines <br /> connected to the site. wastewater would be collected from 220 housing units and the total <br /> dynamic head was determined to be 138 feet. The site could be developed without a pump <br /> Cation'but would include 20,00feet of inch pipe. The cost per connection would be <br /> 25 5 51.24 and the estimated cost for the site totaled $5,487,180.01. <br /> The High School Site would include 730 housing uits and a total dynanmic head of 105 feet. <br /> The cost per connection would be $18,209.22 and the total cost for the site has been estimated to <br /> be $13,310,940.03. <br /> The Keter Site incorporated the island with a force main placed under the river. The site was <br /> diverse and incorporated 1,300 housing units with a total dynamic head of 124 feet. The site, <br /> required a lot of pipe and the cost per connection was $16.,087.43. The total estimate for the <br /> I eeter Site was $20,9941,100.03. <br /> New Seabury would include 550 housing units and would have a total dynamic head of 105 feet.. <br /> The per connection total was $17,270.56 and the-total estimate for New Seabury was <br /> X9,550,620.02. <br /> The Transfer Station Site was another lame area that would serve 1,700 housing units generating <br /> a total dynamic head of 128 feet, The site would require lot of piping. The connections cost <br /> $16)720.81each and the total estimate for the site was $28,927,000.05. <br /> Chairman Fudala inquired about the replacement cycle for the grinder pumps and other <br /> equipment. 11r, Quann reported that here was a 12 year mean time between service calls, <br /> meaning that of 1,000 pumps in the system,-approximately 100 calls would be needed per year_ <br /> Mr. Quann reported that the pumps could be rewired. Mr. Quann recommended that, should the <br /> municipality maintain the pumps, $40450 per year per pump should-be set aside for <br /> maintenance., The Chair referenced the location ofthe-pumps adjacent to the house and inquired <br /> whether gravity could be located closer to the street for public utility maintenance purposes. Mr. <br /> Quann responded that casements had not been a problem, Mr. Quann cautioned against adding <br /> gravity because of the potential for leaks in the systern. Chairman Fudala stated that areas in <br /> 7 <br />
