i, <br /> y <br /> Mashpee had a seasonal population and-inquired whether that would impact the efficiency of the <br /> system. fir. Quann responded that each pump works individually and can pump the wastewater <br /> regardless of the number of people using the system. Mr. MArcelli asked if the existing <br /> wastewater treatment facilities were considered and Mr. Quann responded that he utilized the <br /> planning reap with the assumption that everything within the site would be part of the collection <br /> system. <br /> There was discussion about the proposals from AI VAC and /one,, noting that they ad d re sed <br /> different numbers of unity and areas in Mashpee, with no consideration of areas outside o <br /> Mashpee. Mr. Lyons recommended that the proposals be considered on a cost per unit basis. <br /> The Chair suggested the possibility that different technologies may be utilized in different areas <br /> depending upon the advantages. <br /> The Chair inquired whether there would be savings to assess for gravity instead of low pressure <br /> and Mr. Quann responded that Robert Our indicated that the cost would be doubled for gravity. <br /> The cost of electricity to run the pump was discussed and Mr. Quann indicated that the average <br /> yearly cost for the homeowner would be $40-$50 per year and that the pump was 230 volts. The <br /> pump warranty is two years parts and labor but longer wan-anties are available. lair. Quann <br /> stated that F.R. Mahoney can provide maintenance at a standard service rate of$150 for the first <br /> half hour and $80 per hour plus the cost of parts. Mir. Quante provided a thumb drive containing <br /> the presentation,to Mr. Fudala. <br /> A rec ss was called at 9:00 p.m. to ensure that the exterior doors were open. The meeting <br /> reconvened at 9:07 p.m. <br /> -O r nc /STEP System <br /> Dave Cotton, wastewater Technologies, Inc., is a distributor of the orenco Systems effluent <br /> sewers. Mr. Cotton recently.received 1 lashpee's request because the original contact has been <br /> chronically ill. Mr. Cotton does not.currently have a specific cost.breakdown. Mr. Cotton <br /> referenced use of a 3rd party software that would provide comparisons of different types of <br /> collection systems. <br /> Mr. Cotton described the orenco System as a STEP or STEL design. The STEP system is a <br /> includes a septic tank effluent pump which pumps effluent from a septic tank into a force main.' <br /> If located above the force main, gravity could be used to connect into the same line. The system <br /> has been used throughout the country, in Massachusetts and throughout New England. A <br /> significant advantage to the system involves its flexibility of design and the availability of <br /> emergency storage in.case of a power outage. Emergency storage could extend from 2 to 3 days. <br /> Mr. Cotton indicated that directional boring was recently used to install the system which <br /> eliminated the need to dig up the roads, reducing the-capital costs of the system. The system also <br /> features low operating and maintenance costs. <br /> The effluent pumping system involves a 1,000 gallon watertight tank per home, or a shared tank, <br /> and within the tanl , a pump vault and a control panel.- Concrete and fiberglass tams have been <br /> utilized. Structurally sound, existing septic tanks may be re-used for the system provided they <br /> have been watertight tested. Chairman Fudala inquired about the height of the pump above the <br /> existing tank and lir. Cotton responded that the pump sits within the tame with 9-12 inches of <br /> cover. <br />
