AERATION TO IMPROVE THE WATER QUALITY AND HYDRAULIC
FUNCTIONS OF SEPTIC SYSTEM LEACHFIELDS

INTRODUCTION
Conventional septic systems are designed primarily for effective removal of solids in the
tank and quick dispersal of tank effluent in the associated leachfield. The removal of
nutrients and pathogens takes place with passage of effluent through leachfield soil, but is
not a primary design concern. As such, the capacity of these systems for improving the
quality of effluent water is generally limited. Increasing concern with contamination of
ground and surface waters by failing or improperly installed septic systems has led water
managers and regulatory agencies to promote on-site wastewater treatment technologies
that lower emissions of pathogens and nutrients. With nearly one-quarter of households
in the United States relying on onsite wastewater treatment systems (OWTS) for
treatment of domestic wastewater (United States Census Bureau, 2003), development of
such technologies has the potential to have a significant, positive impact on the quality of
water resources.
