Re: Solution for Septic Field clogging Long Term

We greatly expanded our house some years ago and had to install a whole new septic system. Ours is the first system in the county with an auto-siphon dosing tank, which supposedly prevents field clogging. The dosing tank is connected to the main tank through a plastic filter that won't allow anything bigger than a quarter inch to pass through (the filter needs to be pulled out and hosed off several times per year.) When the dosing tank fills up, a bell siphon automatically dumps 100 gallons of effluent out over the entire field (when the system was being installed, we tested and configured it to wet the entire fiend evenly.) The idea is that the particulates are spread out thinly across the entire field in batches, where they can more quickly break down aerobically, as opposed to trickling all the time at one end of the field, where a crust can form and spread across the field. I think it's been in use about 7 years, and all we've had to do is have it pumped out two times. Tweet
