How to tetrofit detention basins
How to tetrofit detention basins
(OP)
I work in a very flat area. We often use interconnected lagoons (ponds) as detention storage. We also undercut the lagoons 2-3 feet deep for sediment storage. Recently the reviewing agencies are requiring retrofits in front of the connecting pipes between the ponds in order to store more sediment. A retrofit is basically a filtering mechanism designed to slow the water down in order to get more settling. However the pipes are often under water which makes construction difficult. Also I worry about flooding due to putting an obstruction in the pond. Has anyone else addressed this issue? Thanks in advance.
