<br />appear to be necessary to expand over to the Vincent property, however Step #.3 provides for <br />further expansion onto the Vincent property if it becomes necessary. A preliminary cost <br />projection has been made for each step. The following steps appear to most logical order: <br />Step #1-Installation of Flow Equalization Tanks to Control the Peak Flows <br />This step will provide approximately .3,000 GPD of daily wastewater flow and will <br />provide for control of peak flows to 6,000 GPD for' four continuous days, This step will <br />allow for expansion of proposed uses in the center and will allow for some additional <br />capacity for park uses. The projected construction cost of this step is: <br />1,. Subsurface System $ 10,000 <br />2. Additional Tanks -15,000 gal. PS 48,000 <br />.3. Miscellaneous 12,000 <br />$ 70,000 <br />The advantage to Step #1 is that monies aze applied to a cost effective solution of the <br />most important factor that is limiting the expansion of the center.. This step will in <br />essence almost triple the capacity of the existing facility. However, this step does not <br />address the environmental concerns that the existing facility may be contributing to <br />contamination of the groundwater within the water supply watershed, <br />Step #Z -Installation of Pretreatment System to Extend the Life of Existine Fields <br />This step will provide for tertiary treatment of the wastewater prior to disposal in the <br />nitrification fields. This will allow for extended life of the nitrification fields and it will <br />prevent any future contamination of the groundwater. This step may provide for a <br />limited amount of increased capacity depending upon the detailed soil and hydrologic <br />testing to be conducted by the consultants. The projected construction cost of this step is: <br />1. Pretreatment Unit <br />2. Pretreatment Structure <br />$ 64,000 <br />28,000 <br />~ 92,000 <br />The advantage to Step #2 is that monies are applied to both provide environmental <br />protection and to minimize the need for future expansion of the wastewater facility to the <br />Vincent property.. Therefore, this step is a very conservative approach to save money <br />and protect the environment. <br />Step #3 -Expansion of Capacity (if needed) by Adding New Fields Across the <br />Flighway on the Vincent Property <br />This step will provide expansion to approximately 6,000 GPD of daily wastewater flow <br />and will provide for control of peak flows to 12,000 GPD for four continuous days.
