The treatment area should be marked off before construction. This Design is not valid & he System will need to be relocated if failure to protect the areas proposed for On -Site Sewage Treatment occurs. With proper installation and maintenance, this system should have no problem in treating septic effluent effectively. Nothing other than gray water, (laundry, showers, etc.) human waste & toilet tissue should be disposed of into the septic tanks. Garbage disposals are not recommended. Smaller amounts of laundry soaps, dish soaps, cleaning agents, etc. are better for the system. Antibacterial soaps & chlorine agents may kill the bacteria needed to treat septic effluent: properly. Additives are not recommended, they may cause harmful damage to your system. Recommend to pump & clean your tanks by a certified pumper every year if you have 1 tank & every 2 years if you have 2 tanks to insure proper maintenance. � even §chirme�rs DS SBS/ds ,8P, _ . tL t, G 0 0 o A_ CD v I . n 0 x 0 x J n I 1 I_ 1 N « on 1 3 D 7f -/ n x A N 3� f 0 333 a:F a.ga� .. 9 r ^O N v i lal4 X 3 3 3 'go W t� f o � WN— rn N y1 1A A fn rn m m 0 i rr �r n 1 v i 5 l r 1 T Z x Y W � WN— rn 0 7 fn rn m m 0 i rr �big J S ea * d{l MOUND DESIGN WORKSHEET (For Flows up to 1200 gpd) A.
