Septic permits & rules in Mercer County: Mercer County itself does not license, inspect, or otherwise administer septic systems — permits are issued by each municipality's local health department, so homeowners should start with their town's health office. The county's environmental health (CEHA) program covers air, water, noise, hazmat, and solid waste, not septic. Details: Mercer County Division of Public Health (septic is handled at the municipal level).
