I didn't mention our septic but it was perfect set up for us. 2 500 gal. tanks (The former owners had two trailers parked on the property before they built the house, thus two wells and 2 septic.) I have to get the one we use pumped every 2 or three years but there are no dosing pumps or field lines to maintain. I wouldn't do low dosing, aerobics, or grinder pump stations, they are a pain in the ass to maintain.
