As a consequence of its function, the stormwater conveyance
system collects and transports urban runoff that may contain
certain pollutants. Maintaining catch basins, stormwater inlets,
and other stormwater conveyance structures on a regular basis
will remove pollutants, prevent clogging of the downstream
conveyance system, restore catch basins’ sediment trapping
capacity, and ensure the system functions properly hydraulically
to avoid flooding.
