Environmental Engineering - Subsurface Sewage

Approximately 30% of Connecticut's population reside in buildings that dispose of their domestic sewage with on-site sewage disposal systems which are typically conventional septic systems. In addition to serving residential buildings, septic systems also serve schools, restaurants, and other commercial buildings in non-urban areas. A septic system properly designed, installed, and maintained provides a safe and efficient way of disposing domestic sewage. Improper sewage disposal can result in health hazards and nuisance conditions. Sewage contains pathogens (disease causing organisms); therefore it is essential that it be disposed of properly. Jurisdiction of on-site sewage disposal for design flows of 5,000 gallons per day (GPD) and less lies with State and Local Health Departments, and is regulated by the Public Health Code (PHC) Section 19-13-B103 and the associated Technical Standards.
