When you think about the parts of a water intake system that need regular cleaning, the first things that probably come to mind are the screens and spray nozzles, not the screen wells. However, the wells also need regular cleaning, because as with the other parts, if they aren't properly maintained there can be negative consequences.
Traveling water screen wells should be cleaned regularly by a trained dive team to prevent the following maintenance issues:
Accelerated wear of boot components: bearings, foot wheels and shafts.
Accelerated wear and failure of baskets (in particular non-metallic baskets) from dragging through the accumulated sand and grit.
Damage to the system's circulating pump and spray pump if too much built up sand is pulled through them.
Failure of pumps and screens if mud level gets too high and blocks the flow of water into the intake system.
In extreme cases, the a very heavy build up of sand and grit can cause the wall itself to collapse.
Keeping traveling water screen wells clean is just one of the things you can do to keep your water intake system running at peak performance. To find out more routine checks that our experts recommend adding to your maintenance plan, download our Intake Maintenance Checklist.
