Fabric Wrapped Tubes

There are two main manufacturers of fabric wrapped tubes; Enviro-Septic and ADS Geo-Flow pipe. They are almost identical but do have some minor differences. These build an effluent disposal method utilizing 12” diameter corrugated plastic tubes wrapped in a filter fabric. They both can be installed in many different arrangements suiting to the needs of the builder or homeowner.  The length of the rows and the distance between each tube depends on the existing soil, slope, and the load that will be put on the system. Most of this information is gathered during a set of test pits and a perc test. Gravel less tubes are a great system to put in if you have sloping terrain or a small area to work with because they are awarded a significant reduction in size from a stone and pipe leach field by the state of NH.
