Horses, cows, livestock grazing over the septic fields?
The cow is ok in the meadow, and the sheep can't do much damage in the corn, but horses, cows, and maybe some oveweight sheep stomping around in the septic absorption field is another matter entirely.
This article discusses the passage of grazing animals over or near septic fields or other septic system components.
We also provide a MASTER INDEX to this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need.
Grazing Animals Over Septic System Fields?
Is it acceptable to permit grazing animals such as cows, horses, or sheep to occupy a field over a septic system?
No, placing horses, cows, sheep, or other grazing animals over a septic field is a bad idea for several reasons.
Heavy animals are likely to damage the drainfield by compressing the soil and possibly by damaging buried piping. Compressing the
soil over a septic drainfield interferes with soil transpiration, cutting the oxygen level needed by soil bacteria in the biomat and reducing
removal of septic effluent through evaporation.
There is some chance that pathogens from septic effluent may pass to and infect the animals.
More about the chemical and
pathogenic risks associated with plants over septic systems is discussed at Gardens Near Septics.
In sum, it's better to keep livestock off of a septic field. In the photograph just above we show deer grazing on a field along the
Virginia Skyline Drive at Big Meadows.
Deer or other wild animals passing occasionally over a septic drainfield are unlikely to cause serious damage to it.
The page top photograph of mountain sheep resting under trees was taken over a septic field serving a park service building in Jasper, Alberta, and the lower photo was taken of a large herd of deer grazing over a field along the Skyline Drive in the Blue Ridge Mountains of Virginia.
Watch out: If sewage contaminants are present in grass or other forage, those may be a hazard to grazing animals as well as to people consuming meat from such animals. See SEWAGE CONTAMINANTS in FRUIT / VEGETABLES for details.

This comprehensive guide filled with case studies can prevent that. Master plumber R. Dodge Woodson packs this reader-friendly guide with guidance and information, including details on new techniques and materials that can economize and expedite jobs and advice on how to avoid mistakes in both estimating and construction. Chapters cover virtually every aspect of wells and septic systems, including on-site evaluations; site limitations; bidding; soil studies, septic designs, and code-related issues; drilled and dug wells, gravel and pipe, chamber-type, and gravity septic systems; pump stations; common problems with well installation; and remedies for poor septic situations. Woodson also discusses ways to increase profits by avoiding cost overruns.
Country Plumbing: Living with a Septic System, Hartigan, Gerry: $ 9.95; ALAN C HOOD & TP;
Quoting an Amazon reviewer's comment, with which we agree--DF:This book is informative as far as it goes and might be most useful for someone with an older system. But it was written in the early 1980s. A lot has changed since then. In particular, the book doesn't cover any of the newer systems that are used more and more nowadays in some parts of the country -- sand mounds, aeration systems, lagoons, etc.
