SFB maintenance question
SFBs seem to have a tendency to grow vegetation on the surface after a couple of years on line (see photo). Is this a maintenance issue? The sediment accumulation in the basin appears to between .5 to 1 inch in the areas I inspected and I have not noted any issues with the basin not draining out so I don’t think it’s time to remove the accumulated sediment.
I don’t think the vegetation is an issue that needs to be addressed at this time but I wanted to get other inspectors input.
