In the case of Stubbs Bay NW, the distance to any potential <br />useful community drainfield area is much greater than the <br />distance to the municipal sewer. With generally equivalant costs <br />for a collection system, the costs of a community drainfield <br />system would be much higher than the costs of connecting to the <br />municipal sewer. <br />OPTION 5. Installation of individual holding tanks with <br />off -site disposal. <br />Where on -site treatment and disposal of septic tank effluent <br />is not possible due to site limitations, an individual holding <br />tank is often a reasonable solution if: A) the water use is <br />minimal, such as in a seasonal cabin; or B) when construction of <br />collection system with off -site treatment and disposal is <br />imminent. Orono Code allows holding tanks only as a temporary <br />solution for existing problem situations, and never for new <br />construction except on a temporary basis during construction. <br />The cost of installation of a 2,000 gallon sealed concrete <br />holding tank is estimated at $2,000. The yearly maintenance <br />costs are exceedingly high, depending on actual water use. Cost <br />of pumpouts in 1988 is expected to average about $90 per 2,000 <br />gallon load. This cost has risen from approximately $75 per load <br />in previous years partially due to dump charges levied by the <br />MWCC when the pump truck discharges the "septage" (septic tank <br />waste) to the MWCC sewer system. Two extreme residential <br />examples illustrate the costs of maintaining a holding tank <br />system: <br />1) 1 to 2 persons in residence, doing laundry off -site, <br />using water -saver toilets and cor-, vation practices. <br />Estimated daily usage: 30 gpd per per. <br />30 gpd/person x 1-2 persons x 365 lays/yr 2,000 <br />gallons/pumpout = 6-11 pumpouts required/yr. <br />6-11 x $90 = $540-990/yr. <br />22 <br />
