Small Waste Water Discharges Registration Criteria
EPA guidance on Small Waste Water Discharges Registration Criteria 2026
Summary: In November 2025, the Irish Government approved the introduction of a new regulatory approach for wastewater discharges from small-scale housing developments. The system will see wastewater from developments of up to 40 homes regulated through a registration system and compliance with General Binding Rules (GBRs). The GBRs establish binding requirements relating to housing development size and discharge volume as well as setting treatment performance standards to be met. Operational and maintenance requirements are set out as well as incident reporting and environmental monitoring obligations.
