Over half of our backyard is taken up by the septic distribution field and I’ve been told by some people that this half of the yard should never be used. Well, can we or can’t we? We originally wanted to set up a volley ball court here but again someone told us that the constant pounding of feet would collapse the field and it would thus fail. So, what can we do with this half of the yard – anything?
j09ln03, if your “distribution field” is an evapo-transpiration (ET) bed, then heavy foot traffic will negatively impact the ability of the wicking sand to function properly, and the bed will become a sodden mess. If however, you have a standard soil absorption system, with fairly permeable soils, then the foot traffic applied with an occasional volleyball game should have no effect on the proper performance of the leach field. Do not drive heavy motor vehicles over any type of final dispersal field, not even occasionally. This means “NEVER”.
Of course, if you have only one leach field, then it will fail at some point in time. Its service life may be many years, but soil absorption systems without the ability to “rest”, (alternating leach fields) will eventually fail, whether or not you have an occasional volleyball game above it. JWA
