Everyone knows the saying “work smarter, not harder”. But in municipal collection systems, preventative maintenance strategies have followed a “work harder” approach. This is because, in the typical system, over 70% of gravity sewer lines are unobstructed, and using traditional time-based or rotational cleaning strategies, utilities waste resources by cleaning all pipes that do not need cleaning. This inefficiency is compounded by other common challenges such as employee shortages, aging infrastructure, budgetary constraints, and the need to conserve water.
