Septic Tank Companies in Connecticut
197 septic service companies across 116 cities — approximately 35% of Connecticut homes use septic systems
Connecticut's septic systems are regulated by the Connecticut Department of Public Health (CT DPH) under the state's Public Health Code, with local enforcement handled by town health departments and health districts across the state's 169 municipalities. Connecticut's glacially deposited soils — ranging from well-draining sandy gravel in the Connecticut River Valley to tight, poorly draining glacial till on hillsides — significantly influence system design in every town. The state's high population density, relatively small lot sizes, and proximity of wells to septic systems make proper design and maintenance critical, particularly in towns like Woodstock, Pomfret, and Brooklyn in Windham County where rural residential development relies heavily on private wells and septic.
