District enhances efforts to capture and remove debris
The District routinely maintains more than 50 containment booms throughout its 500-mile canal network. To enhance efforts to capture and remove floating debris, the District has recently replaced and upgraded more than half of these booms.
Containment booms are floating ribbon-like structures that span the canal cross-section and extend approximately one foot both above and below the water surface. As water flows through a canal or as winds blow across the water’s surface, floating debris will move through the canal network. The booms serve as a physical barrier, “corralling” the debris while allowing water to continue to flow unimpeded.
Installed at critical locations in order to concentrate floating vegetation and other debris, the booms allow District vegetation management crews to more effectively collect, treat and dispose of the material. This approach significantly reduces the quantity of undesirable floating material that would otherwise move downstream during excessive rainfall events and flow into ecologically sensitive water bodies or adjacent neighborhoods.
Without the use of containment booms, District vegetation management crews would have to traverse every mile of its 500-mile canal network to find, treat or remove floating vegetation and other debris before it could move downstream and become a nuisance. Over the next year, the District will continue its efforts to replace and upgrade the remaining booms in order to realize additional efficiencies and costs savings associated with time and materials necessary to maintain the canals.
