STUBBS BAY ALTERNATIVE WASTE MANAGEMENT STUDY <br />SUMMARY <br />Pursuant to provisions within the Orono Comprehensive Sewer <br />Policy, 82 developed residential properties and 13 additional <br />vacant properties located in the Stubbs Bay area of Orono were <br />the subject of an Alternative Waste Management Study. Each <br />developed property was analyzed and inventoried to determine the <br />design, location and condition of existing septic systems and to <br />estimate the potential capability of each property for <br />replacement of existing septic systems. <br />In addition, various optional methods of sewage treatment and <br />disposal were studied. These include alteration of user habits, <br />repair or replacement of existing systems, use of innovative on - <br />site systems, use of a collection system with community <br />drainfield, use• of individual holding tanks, selective <br />condemnation ana demolition, and installation of municipal <br />sanitary sewers. <br />Within the study area, 24 of 79 existing wells were found to be <br />located less than the required minimum 50 feet from any portion <br />of a septic system. In addition, 13 of 82 existing systems were <br />found to be discharging to the surface or located so as to have a <br />high probability of causing untreated effluent flow directly <br />underground to Stubbs Bay. <br />The study found that approximately one-fourth of the properties <br />within the study area could not install a conforming replacement <br />septic system if their existing system failed. An additional <br />one-fcurth of the properties would be expected to experience <br />severe limitations in replacing their septic systems due to site <br />constraints. Only 50% of the 82 properties in the study area <br />could be expected to successfully use septic systems on a <br />permanent basis. <br />
