MINUTES March 2, 1995 2 BOARD OF HEALTH <br /> of recirculation and a hard time making a plant that has been built for a larger effluent <br /> volume and concentration work." "We wanted to stay away from that and thankfully <br /> there has been enough history developed with people who have had plants that are hard to <br /> use that the regulating authorities are now more open to discussion as far as those things." <br /> "The original study done by Weston & Sampson was to outline what the possible largest <br /> worst case scenario would be for the town of Mashpee and that came up to 40,000 gallons <br /> per day on an average day on the town of Mashpee's portion." "That was an absolute <br /> worst criteria and is not their idea of what the design criteria would be but it was putting a <br /> ceiling on what we could ever be at build-out." "Dufresne Henry has gone through all the <br /> septic tanks that we know of that are located in both towns, gone through the pumping <br /> records available, gone through projected build-out densities and came up with a design <br /> flow for both towns as being 15,500 gallons based onfa four to five year pump out rate for <br /> both towns." "In talking with the regulators at D.E.P. they wanted us to see what would <br /> happen if everyone did pump out on a three year basis and that changes the effluent to <br /> 26,000 gallons per day." "Taking that and going along with the actual suspended solids <br /> and biological oxygen demand required by the effluent that has been measured at <br /> Yarmouth, Tri-town, Barnstable, Westboro and Wayland and tests that we've done on our <br /> effluent that's been discharged in these towns, it appears that our design loads for solids is <br /> considerably lower then what previous design areas were." "The regulating authorities in <br /> Boston and in the Southeastern Region, Brian Dunahoe and Bob Fagen, who happened to <br /> summer in Popponesset, have agreed to this number and what it has generated is that the <br /> bottom line is that we're looking a total construction cost of about 1.3 million to get us <br /> into phase I for a very long time, that's for both towns combined." "That relates to a Iow <br /> flow cost of about .7 cents a gallon and more of a design flow cost of.6 cents a gallon." <br /> "That is the cost of operations." "We have one more meeting on April 5, 1995 to go <br /> through some scenario's and further chase down these numbers and refine them to see <br /> precisely what it looks like." "We will also be at the point where, having gone through all <br /> their concerns every step of the way, once the final design comes about it should be much <br /> easier for them to review and have fewer discussions about design criteria because we <br /> have already been through all that." "After the April 5, 1995 meeting we're expecting to <br /> be in the position where we will be ready to have a meeting with the joints groups of <br /> Selectmen from Sandwich and Mashpee to give them a presentation on what needs to be <br /> done in order to get into final design and what we're doing." <br /> Mr. McQuaid stated, "Steven GreeIish, up until the time he resigned, volunteered <br /> to stay on this particular committee for the joint treatment plant." "It is my understanding <br /> that his involvement is negligible is anything." <br /> i <br />
