Debris Boom for Protection of
Intake Screens
Question regarding a debris boom around intake screen. We have a need for a debris boom to keep leaves, sticks, limbs from getting into our intake screen from the river. The main problem is fall of the year when leaves fall and the rainy spring time. I think about 300' with about 5 to 7' for curtain with a heavy hold down chain.
The water goes from about 2 mph to about 15 on high water flow. The level goes from 594' elevation (about 4' deep) to 620' at flood stage. Lots of trash comes down with back wash that cause material to drift to our screens. We have a 12" poly floating log that does not do much for the material coming under it. What are your thoughts?
Answer:
Greetings! Thanks for contacting Granite Environmental. I agree that a debris boom would be best for this particular application. As a comparison to your existing poly log, this debris boom around intake screen will typically contain a small skirt (usually either six or twelve inches in depth) that can help with containment underneath the surface of the water. If you think that a longer skirt would be required, this requirement can also be met upon request.
Another option you could consider when using this type of boom is some type of material to help with a clean up process. Items like removable trash baskets, nets, and vacuums have all been used to clean up materials contained by a boom or barrier. This material can be readily recovered by the storm water or public works departments to keep your intake screen free from debris.
We carry several debris boom around intake screen models and floating debris boom sizes IN STOCK suitable for rivers, lakes and canals. This economical containment boom design is suitable to contain small timbers, styrofoam, litter and aquatic plants and is the work horse of our debris boom family. Floatable boom debris sizes vary depending on the site conditions and also the type of water pollution (aquatic plants, plastic bags, Styrofoam, etc) being experienced. Boom that is suitable for use in controlling most lake pollution can normally not be used for river pollution control due to the hydraulic loading on the barriers.
