ANALYSIS <br />The report specifically addresses the following types of effluent <br />storage and disposal along with there costs: <br />1. Effluent reuse by irrigation <br />2. Effluent storage/infiltration basins <br />3. Effluent storage/lined holding basins <br />4. Rapid rate infiltration basins <br />5 Deep well injection <br />The present effluent disposal system consists of 3 rapid rate <br />infiltration basins. These basins will not be adequate, and even <br />with the construction of additional infiltration basins the plant <br />site does not appear to be large enough to accommodate the <br />anticipated wastewater flows of the near future. <br />CONCLUSION <br />In the conclusion of the feasibility study it is basically recom- <br />mended that the County pursue effluent reuse through irrigation <br />along with a backup storage capability utilizing lined storage <br />basins. The reuse plan is the least expensive and the most <br />attractive to the environmental and water use regulatory agencies. <br />The reuse program would consist of the purchase of the sod farm <br />located adjacent to the wastewater treatment plant to provide a <br />large tract of land that would provide a continuous county con- <br />trolled effluent disposal site. In addition, it is recommended that <br />agreements be pursued with nearby agricultural (citrus) and golf <br />course interests to provide irrigation as needed by those interests. <br />Through these agreements effluent would be utilized for agricultural <br />and golf course irrigation when needed and alternately disposed of <br />or stored on County controlled property when not needed. <br />On page 7-8 of the feasibility study the following courses of action <br />are recommended to implement the reuse program.' <br />I. Commence negotiations for irrigation contracts with <br />landowners of the properties that the study recommends for use <br />as irrigation sites in the initial two phases of the reuse <br />program. <br />2. Perform hydrogeologic modeling of effluent disposal system <br />to determine impacts. <br />3. Perform detailed site-specific studies for the proposed <br />application areas. <br />4. Perform detailed survey of exisiting potable water systems <br />that will be impacted by disposal systems. <br />5. Commence with design/permitting of recommended disposal <br />system. <br />RECOMMENDATION <br />Operation of the west regional wastewater treatment plant has only <br />recently begun and the present flows are already in excess of <br />100,000 gallons per day. With the limited effluent disposal capa- <br />city of the existing rapid infiltration basins it is imperative that <br />we immediately pursue additional and alternative means of effluent <br />disposal to provide service to new development and those develop- <br />ments that need to phase out their problematic wastewater treatment <br />plants. <br />19 <br />JUN 111986 <br />BOOK 64 6S I <br />I <br />
