SITE COPY A pressurized mound system was design for the above property on 6/28/10 and the drainfield was sized out for a 2 bedroom home ( 300 gal/day). However the actual size of the house will be remodel to.be a 3 bedroom home or a dailv L water use of 450 gal/day, therefore the size of the drainfield will have to be increase. The size of pressurized bed needed for a 3 bedroom home would be the following ; Overall size;--900 sq.ft. This would amount to a L-shape type bed with the dimensions of a 70 ft.long by 30 ft. wide and a 40 ft. long by 5 ft.wide (2 beds ) for a combine 900 sq.ft. to Amount of pressurized laterals needed; 5 total laterals --Use 2-inch pipe for the laterals '@ I 1) 3 laterals–68 ft. long and 2-38 ft. long AV Its Size of perforated hole size 3/16 inch that is space out 3 ft. apart on center. Pump size;; 40 gpm--- must overcome at least 10 ft. of head pressure Pumping rate-192 gal/cycle ( this amount is needed to satisfy the requirement of 4 times the total lateral volume which is 48 gallons ) Size of septic tanks needed ; 2-1000 gallon tanks SITE COPY Size of pump tank needed; 1-1000 gallon tank. Amount of Sand needed;---75 yds., 15 tons-2 ft. deep Amount of Rock needed;--45 yds., 63 tons Total depth-1.4 ft. ( 2 inches above the 2 inch pipe ) Amount of Topsoil needed over the entire system would be 45 yds.. Total depth 9-12 inches the above amounts could vary by 10 %plus or minus. As mention in the 6/28/2011 there is approximately 2 ft. of fill present, therefore same construction procedure specified out in the 6/28/2010 shall be used when constructing this Qawd d system.
