The key to proper septic absorption is having a field with good leaching soil that is free of rocks and clay. If your absorption field is sitting below the water level where you live, you'll have some trouble dealing with flooding in your yard if it rains. The Department of Environmental Quality (DEQ), (https://www.deq.state.ok.us/ECLSnew/index.htm ) requires property owners to complete a soil test (Form 581) to determine the type and size of system.
A clear, level area with a gentle slope is perfect for drainage conditions, and while large trees can pose a problem, small vegetation is the perfect cover for to prevent people from walking where they shouldn't. Make sure to keep this area free of parked vehicles, and never plan on building something over the area as the soil will be too moist and full of waste to properly hold the weight of a new structure.
