Reserve must be minimum 563 gal. <br /> 4) A five (5) bedroom home requires 2,250 gal. septic tanks, min. <br /> 5� I assume the system is a pressure bed with 8 lines; but on page <br /> i ;t ss�ows 8 trenches 44` lc�i��. <br /> 6) If pump line has less than 3'1/2' of cover, it must be insulated. <br /> 7) The design shows over lapping the old system in part. Is the <br /> system Type 1 or Type 3? <br /> If there are questions, please give me a call. <br /> METRO WEST INSPECTION SERVICES.
