Site Disapproved: Reasons for rejection: 1. Position in landscape subject to flooding or periodic saturation. 2. Insufficient depth of suitable soil over hard rock. 3. Insufficient depth of suitable soil to seansonal water table. 4. Rates of absorption too slow. 5. Insufficient area of acceptable soil for required drainfield, and/or Reverse Area. 6. Proposed system too close to well.

If the topography is not uniform across the length of the site the trenches will need to flare apart on one end to maintain contour. When this occurs it is necessary to use a center-to-center spacing that accounts for the flair or the installer will not be able to fit the system within the approved area. It is perfectly acceptable to have more area available,especially up and down the slope,than is required.
