+ ,r <br /> MINUTES February 9, 1995 2 BOARD OF HEALTH <br /> Mr. Rowland responded, "The smallest is 900 gallons, we would prefer to have <br /> 1500 or 2000 gallons." <br /> Mr. Ball questioned maintenance. <br /> Mr. Rowland responded, "Pumping and the air blower." "There is only one <br /> moving part, the air blower." "The system is gravity fed." "If electricity is lost the system <br /> would revert back to Title V." "The system is fully alarmed and monitored." "The system <br /> is rated from 100 gallons per day up to 1000 gallons per day." <br /> Mr. Doherty commented, "Then we're looking at year round homes, not <br /> necessarily seasonal." r <br /> Mr. Rowland stated, "I would say a seasonal if it was a six month season." <br /> Mr. Dunlap stated, "It takes about seven days to fully charge or get this thing <br /> going." "If you have a situation where it is a weekend cottage, one of the advantages of a <br /> submerged media is that it will retain the biogrowth over that week span." "It's very good <br /> at taking shock loadings." "It's good for resorts, restaurants and places that have a <br /> fluctuation in loadings." "If your going to shut down for a six month period and have no <br /> flow then what you are really doing is reverting back to a septic tank." <br /> Mr. McQuaid questioned, "Do you have data substantiating your nitrogen <br /> reduction?" <br /> Mr. Rowland responded, "Yes, NSF did it." (Mr. Rowland presented the NSF <br /> report.) <br /> Mr. McQuaid questioned Mr. Rowland, "Do you have something from D.E_P. <br /> indicating their approval." <br /> Mr. Rowland responded, "We do, but it is basically out for comment." "I would <br /> prefer that it be published first." <br /> Mr. Dunlap stated, "In Cohasset all the units are being designed with the UV <br /> system in it." <br /> Mr. Ball requested a copy of the results. <br />
