We replaced our 20 year old septic tank and field with a advanced water treatment system and at grade last fall.
The existing tank and field were undersized, and also sandy soil. We had the option of adding another tank and a new field, this would require two pumps, more to go wrong and the field on the front lawn, wife didn’t like that. The cost was double the price of the conventional tank and field, the upside fields in the bush out of the way. The at grade was installed on a side hill, all the work was done by hand and shovel.
