Overview

Advanced Onsite Wastewater Systems Technologies

The recognition by the U.S. E.P.A. of onsite wastewater systems as a permanent part of the nation's wastewater infrastructure has renewed interest in this field among wastewater industry professionals. With over 30 years of combined knowledge and experience in the various aspects of onsite systems, the authors present their views on the current state of onsite technologies and how these technologies can be used on a wide-scale basis to overcome the common problems associated with conventional septic tank and drain field systems. The book also covers the regulatory and management infrastructure needed to ensure long-term reliability of onsite wastewater management systems.
