6 DEVELOPMENTAND EVALUATION OFALTERNAT~VES <br /> <br />the land lease agreement would remain in place. Advantages and disadvantages of this <br />alternative are listed below. <br /> <br />Advantages: <br />o Reclaimed water main already constructed to the SIWF <br /> Lowest cost alternative for beneficially using the SIWF <br /> Provides MWlvIC with a readily available effluent reuse location <br /> Maintain small revenue source through lease agreement <br /> <br />Disadvantages: <br /> Costs associated with modifications and equipment required to apply liquid biosolids to <br /> the site <br /> <br />The fact that the reclaimed water main from the WPCF is connected to the SIWF makes this <br />an attractive alternative. Effluent could be applied at the SIWF with minor ~_spection and <br />retrofitting of the sprinklers on the center pivots. This cost is estimated at approximately <br />$2,000 per pivot. <br /> <br />Liquid biosolids from the BMF could also be applied to the SIWF with relatively minor <br />piping/equipment additions. Applying liquid biosolids from the BMF to the SIWF would <br />require the following improvements/modifications: <br /> <br />, A new pipeline from the BF pump station to the SIWF that would convey liquid <br /> biosolids. It is assumed that the existing liquid biosolids pumps would have enough <br /> capacity to pump to the SIWF. <br /> <br />· A hose reel system with distribution pipeline. The onsite distribution system would <br /> consist of three hose reels to spread the liquid biosolids on poplars or grass. <br /> <br />· A booster pump station to distribute biosolids to the hose reels. <br /> <br />Alternatives Cost Comparison <br />Table 6.5.5-1 provides a cost esFnnate comparison between alternatives.
