Which option is a method for managing risks related to sewer line interference?

Using liquid sealants to restore pipe integrity is a recognized method for managing risks associated with sewer line interference caused by tree roots. Over time, tree roots can penetrate sewer lines, leading to blockages and pipe damage. Liquid sealants can fill gaps and cracks in the pipes, repairing them and preventing further intrusion by roots. This method is effective in mitigating potential damage while allowing for established vegetation to remain in place, thus avoiding the need for drastic measures like tree removal or aggressive pruning that could compromise tree health and stability.

This approach also balances the demands of urban forestry with infrastructure maintenance, addressing immediate concerns about sewer lines while recognizing the value of trees in urban settings. By restoring the pipe's integrity, the risk of future issues can be significantly reduced, thus ensuring a sustainable solution.
