Your septic system site plan is typically drawn right on top of your property survey showing the septic tank ‘setbacks’ with tank 5-10 feet from the house, the leach field at least 20 feet from the house, at least 100 feet away from wells and streams, 25 feet away from dry gulches, and 10 feet away from the property.
How far should leach field be from septic tank?
Common guidelines require at least 50′ clearance distance between a well and a septic system tank or 150′ between a well and a septic drainfield or leaching bed but you will see that different authorities may recommend different distances. Local soil and rock conditions can make these “rules of thumb” unreliable.
Can a leach field be higher than septic tank?

Unless a septic pump or effluent pump system are installed (you’d find wiring, and perhaps alarms) the drain field is going to be at or below the elevation of the septic tank.
How close to a leach field can you build?
– A full foundation must be 10 feet from the septic tank and 20 feet from the leaching area. – A slab foundation such as a garage must be 10 feet from the septic tank and 10 feet from the leaching area.
How do you dry out a leach field?

Where should a leach field be placed?
