Leach Field

1. The smallest field, with lowest health risk, operational cost and problems, comes from the Multi-Pipe dispersal option.

2. The highest health risk, operational cost and operational problems come from the surface dispersal option.

3. For a spray dispersal field, Regulators, Designers, and Installers must warn the owner, in writing, of the high operational cost and problems, the high health risks, and the requirement for continuous disinfection.

4. For a “dumb” drip dispersal field, Regulators, Designers, and Installers must warn the owner, in writing, of the moderate health risks, high operational cost and problems, and should suggest continuous disinfection of the effluent as a safeguard.

5. For lower operational cost and problems, and lower health risks, the owner should be offered Conventional, Multi-Pipe, Chambers, LPD, or “Smart” Drip, in that general order, wherever feasible.
