With the minimal drainfield, tank pump-outs would likely <br /> only be needed once or twice a year at a typical cost of $100 per <br /> pump-out. Without the drainfield, pump-out costs could easily exceed <br /> $2500 per year depending on the actual household waste load. <br /> Once a decision on the sewer is reached, if the project goes ahead, <br /> a 1 1 residents served with sewer wi 11 be required to connect to it <br /> within 16 months of the time it is available, and abandon their septic <br /> systems even if they are operating effectively. This is a <br /> City ordinance. <br /> If the sewer project does not proceed, at such time that Ms. Stewart's <br /> septic system is found to be failing, the permanent solution would <br /> involve the following: <br /> A. Soil testing and system design work wi11 be needed before a <br /> repair permit could be issued. Estimated cost: $500.00. <br /> B. Based on our preliminary investigation, this site would <br /> require a sewage treatment mouncl system due to high seasonal <br /> water tables. Using the 1500 gallon storage tank as a <br /> septic tank, Orono Code would require an additional septic <br /> tank and a pump tank, with dosing pump and high water alarm. <br /> These tanks and the mound system to serve this 3-4 bedroom <br /> home would cost the range of $7500 , in addition to the <br /> initial storage tank and soil testing costs. <br /> 'TEI.EPHONE-473-7357� FAX-473-0510 <br />
