Alternating Disposal Fields

Alternating Disposal Fields. 1. An alternating effluent disposal field system provides two complete disposal fields, separated by a valving system so that each system could alternately be used and rested. This “resting” is useful in regenerating the soil’s capability for absorbing the effluent. 2. The size of each field can be from 50 to 100 percent of the required square footage of a single disposal field. 3. The length of time each field would be used and then rested will be determined on a case- by-case basis.
