The <br /> treatment system O&M cost is estimated to be$58.000 per year. <br /> i <br /> The O&M costs related to the dispersal system are associated with the replacement of <br /> valves and pumps in the dispersal system dosing tank system. The estimated O&M cost <br /> for the dispersal system is estimated to be$6,000 per year. <br /> r ` <br /> TABLE 4 <br /> f OPERATION AND MAINTENANCE COSTS <br /> a <br /> LIN FAMILY PROPERTIES <br /> System_ O&M Cost <br /> Collection $23,000 <br /> Treatment $58,000 <br /> Dispersal $6,000 <br /> Total $87,000 <br /> E� <br /> 6.0 OTHER ISSUES <br /> f <br /> 6.1 System Area Requirement <br /> i; <br /> i Col feet]on'!sy stem infrastructure is anticipated to be located in streets and Nvill not require <br /> additional area in the development.
