Important Updates to Drain Disposal Restrictions

February 27, 2025

The campus Drain Disposal Restrictions have been revised in an effort to simplify the guidelines and mitigate improper disposal practices. Discharge of hazardous chemical wastes into the municipal sanitary sewer system is prohibited by campus policy and is regulated by federal, state, and regional laws. UC Berkeley is committed to the protection of the local community and the environment.
