HB 5749 Connecticut House · 2025 Regular Session

AN ACT CONCERNING ADVANCED SEPTIC SYSTEMS WITH NITROGEN-REMOVAL FEATURES.

HB 5749 requires new residential and commercial developments, major renovations (increasing wastewater by 25%+), and replacements of failing systems in "environmentally sensitive areas" to install nitrogen-reducing septic systems. These systems must meet performance standards set by the Department of Public Health and undergo annual inspections. The bill applies to properties in designated zones at risk from nitrogen pollution, such as coastal areas, watersheds, and near drinking water sources. It takes effect October 1, 2025, with departments required to establish standards and designate sensitive areas by March 2026.
