A decade of experience with dozens of residential greywater systems led ecological designer Art Ludwig to question everything about conventional greywater system design. He stripped away every possible bit of complexity until the essence of a greywater system remained: a pipe network for distributing water from the house to a number of trees around the yard.
Branched drains provide economical, reliable, sanitary, low maintenance distribution of household greywater to downhill plants without filtration, pumping, or surge tanks. "Branched Drain Greywater Systems" describes how to design, build and use a branched drain greywater system from off-the-shelf components, in just about any context. 51 pages, 24 figures, 42 photos. 8.5 x 11 inches.
Topics include: advantages, disadvantages, and limitations of branched drain systems, designing a system, assessing greywater sources and irrigation need, checking levels with a water level, selecting plants, estimating irrigation need, cost/benefit analysis, installation, laying pipe with marginal slope, branched drains for Third World materials and conditions, mulch basin design, maintenance, system examples, and references and suppliers.
