Collections Department

The Environmental Protection Agency mandates that the District check and clean the entire sewerage system which adds up to approximately 160 miles of pipe every five years.

To accomplish this, the Collections team sends a camera into the sewer lines – a robot on wheels. An operator controls the camera remotely, looking for cracks or blockages in the pipes. About 4,000 feet of pipe are televised each week.

If there is an obstruction, they call in the heavy artillery. The team uses high pressure nozzles to blast and cut obstructions. They range from ultra high pressure nozzles for removing root balls to low pressure nozzles for simple cleaning. In a normal week, approximately 8,000 feet of pipe is cleaned.

Cracked or damaged pipes are logged into the Pipeline Assessment Certification Program and rated on a scale of 1 to 5 with 1 being for small cracks and 5 being for severe cracks, missing pieces of pipe or root infiltration.

The Collections team accurately maps all trouble spots and catalogs the needed repairs for the Construction Department.
