1 <br />' costs for operation and maintenance (0&M) were also compared between the <br />two alternatives in Table 6-1 using similar cost-effectiveness analyses as <br />ta guide. <br />From Table 6-1, it is evident that grinder pump -pressure sewers are more <br />' cost-effective than either gravity sewers or a STEP system in the study <br />area. Capital costs for low pressure sewers were found to be approximately <br />' 25 percent lower than those for conventional gravity sewers. Overall, <br />pressure sewers were found to be approximately 10 percent less expensive <br />' than gravity sewers to construct, operate, and maintain. Also, the <br />pressure sewer system would not be difficult to implement in the small <br />' study area, due to the relatively close proximity of the study area to the <br />Vero Beach Wastewater Treatment Plant. Capital costs for low pressure <br />sewers were found to be approximately 10 percent lower than those for the <br />iSTEP system. Overall, pressure sewers were found to be approximately 12 <br />percent less expensive than the STEP system to construct, operate, and <br />maintain. Therefore, a grinder pump -pressure sewer system was developed <br />for the study area. Section 8 presents the preliminary design of this <br />' system. <br />' IRC.VB4 <br />6/4/87 <br />6-7 <br />
