Design and Installation of Low-Pressure Pipe Waste Treatment Systems

摘要

Many sites under consideration for development in North Carolina are not suitable for on-site sewage disposal by conventional septic systems. Among these sites are some which do have enough depth and area of usable soil to provide safe disposal via low-pressure pipe (LPP) systems. This manual specifies the procedures and materials to be used for successful siting, design, installation and maintenance of residential LPP systems. Use of proper materials and techniques is critical to the success of the LPP, as well as to all other ground absorption systems. Many engineers, sanitarians, contractors and designers are unfamiliar with LPP construction, and these instructions are designed as an aid to them.
