The Septic System Owner’s Manual … Lloyd Kahn, Blair Allen and Julie Jones. This book takes a middle ground between the radically simple Jenkins system (Humanure, above) and the more conventional approach described in mainstream books on septic systems. Lots of great illustrations and humor make this important material easy to absorb. Pages 112-115 alone, showing 20 different systems for different situations, is worth the book’s price. And fixing septic system failure is also covered. 8″ by 9″. 164 pages.
