What is a Flout?
Flout stands for “Floating Outlet”. It’s a new way to flood septic system effluent into the leach field. It floods the distribution box with water well above the invert of the leach pipes, and insures an equal, fast flow of water down all legs of the leach field. What does it do? It holds back the water coming from the septic tank until enough is collected to flood the leach field. When the discharge cycle starts, all the stored water is fed to the D‑box and flows out every leg of the leach field. After discharging is completed, the septic tank water is held back until another full charge of water is collected. This gives the leach field time to rest and absorb the water that has flooded it. The flooding action insures the entire leach field sees water every time the tank discharges utilizing more surface area of the soil to treat the septic effluent than that of a standard trickling leaching system. If you have a 300-gal charge, 200′ of 24″ wide leach field, each square foot of trench
