The holding pond serves as both to recirculate flush water through the freestall barns and to store nutrient water for eventual irrigation. As flush water flushes the concrete alleys, the manure-laden water along with sand used for freestall bedding flows into a"sand trap"where the sand particles drop out of suspension for reuse as bedding. The manure solids and nutrient water continue on to the solids separation basin that is accepting the flow. As each separation basin becomes saturated with solids, the flush water is diverted to the next basin, while the full basin is allowed to dry out. Manure solids are then excavated and transported to the Manure Storage Pad (MSP). At the start of the winter months the basins are completely cleaned-out and the holding pond pumped down to create storage capacity. Storage Volumes for each containment structure, along with the tailwater and primary irrigation conveyance ditch are based on the following formula. The primary irrigation conveyance ditch may also be considered as a storage containment structure for the Home Ranch since it can store rainwater and nutrient water during the rainy season: Volume in cubic feet(ft')_(LW x LL x LD)- [(S x LD')x(LW+LL)]+(4 x S'x LD'—* 3) Where: y LW=Liquid Width,ft LW=EW-2 x FB x S EW=Earth Basin Width,ft LL =EL-2 x FB x S FB= Freeboard,ft(2 ft) LD =ED-FB S = Sideslope,ft LL= Liquid Length,ft EL= Earth Basin Length,ft LD= Liquid Depth,ft ED= Earth Basin Depth,ft HOLDING POND STORAGE VOLUME a..
