Description:
Spokane County Environmental Services has two video inspection crews. Our program is to inspect each gravity sewer line every 10 years. New sewer lines are inspected before being put into service. Also, problem areas are inspected more frequently. There are over 658 miles of gravity sewer pipe in our system.
Significance:
The video inspection program identifies sewer line faults including cracks, roots, obstructions, groundwater infiltration and evidence of backups. This information is used to identify repair projects and develop a condition rating for the sewer system. Our crews are doing very important work every day that results in fewer backups and excellent service to our customers.
