Flow Measurement— Flow measurement devices will be provided to measure the flows from the <br /> sump pumps to the FAL and from the final cell of the facultative aerated lagoon to the irrigation <br /> system. <br /> 7. Filter—A filter will be provided to screen secondary effluent prior to vineyard irrigation. <br /> 8. Irrigation disposal (reuse) -- Final reuse (disposal) of effluent would be accomplished by spray <br /> irrigating approximately 79.2 acres of pasture. The percolation capacity of the soils on site was <br /> determined to be 0.125 inches/hour based on Condor Technologies Percolation Test Report dated <br /> September 1998. The reported value was reduced by a safety factor and applied only to the <br /> number of operating days based on NBRID data for 100 RP. For example the wet season <br /> (December through February) monthly application rates were significantly reduced because only <br /> 5-6 days per month were assumed to be operating days. The annual irrigation demand exceeds <br /> the estimated annual process wastewater volume. See the pond water balance in Enclosure C for <br /> proposed effluent storage and diversions to irrigation disposal. Double check valves or similar <br /> backflow prevention devices will be installed on the irrigation system discharge to prevent any <br /> cross-contamination with treated effluent applied to the irrigation distribution network. See <br /> Enclosure D for proposed irrigation application rates to the reuse areas. <br /> M <br />
