Where must the abandonment of existing building sewer connections be securely sealed?

The abandonment of existing building sewer connections must be securely sealed inside the curb line. This is essential for several reasons:

1. Preventing Contamination: Sealing the sewer connections at this point helps prevent any potential leakage of sewage or wastewater into the environment or local water systems, protecting public health and the ecosystem.

2. Ensuring Public Safety: By sealing within the curb line, any risks associated with open or improperly abandoned sewer connections that could pose hazards to pedestrians and vehicles are minimized. This creates a safer environment around the property.

3. Compliance with Regulations: Local plumbing codes typically require that sewer connections be abandoned in a manner that prevents any possibility of future use or disturbance. Sealing at the curb line aligns with these regulations, ensuring that the property meets all local requirements and standards.

4. Maintenance of Infrastructure: Proper abandonment at this location ensures that municipal sewage systems remain intact and function correctly, preventing blockages or other issues that could arise from unresolved connections.

These factors reinforce the importance of sealing abandoned sewer connections securely at the curb line rather than at other points like the property line, main sewer line, or foundation wall, which might not adequately isolate the abandoned system from the active infrastructure.
