Featured Video: Sewer Cleaning in Los Angeles California with Kent Carlson

For roughly 30 years Kent Carlson worked for the City of Los Angeles to bring innovation and new technology to the Department of Public Works’ Bureau of Sanitation. When the Bureau observed that new technology was falling behind on their collections side, Kent was brought over to assist with tool development and the standardization of sewer cleaning procedures. Under the mission to reduce sewer overflows and recognize increasing drought in southern California, one of his favorite inventions featured a sewer nozzle designed to reduce water use and save time during cleaning.

In his article with CWEA Water News he offers his predictions on the future of the sewer profession asserting, “I think it’s an exciting future – technology is exploding in this sector – CCTV, GIS, computers on the trucks. Sewer workers of the future will be much better with technology. Rather than using rudimentary brute force for cleaning we’ll get smarter, more strategic and more efficient at what we do.”

Kent’s enthusiasm for tool development is demonstrated in this week’s featured video. The 5-minute video highlights the history of sewer cleaning in Los Angeles as well as a demonstration of how his team tests and develops their sewer cleaning tools. Back in the day, sewer cleaning featured manual removal of clogged pipes and sewer mains. Today, his team takes advantage of high-pressure tools and robotics. Kent says the best tools for sewer cleaning are designed or personally modified by the facility staff. These tools ultimately help the Bureau of Sanitation affordably maintain approximately 6,500 miles of pipe, some of which was originally installed as far back as 1883. We hope this week's featured video inspires your system to find new and innovative ways to help your utility operate more efficiently.
