The Division's preventive sewer maintenance program includes cleaning approximately 2,000 catch basins annually, routine inspection and flushing of 75 problem pipe lines, and working with food establishments to limit the adverse effects of grease on sewer lines. All of these activities serve to reduce emergency sewer backups and flooding and to protect water quality. The Division also plays a key role in the response to storm events that produce street flooding.
