SMF Components Replacement

Eventually, like most infrastructure, actual BMP components will need to be replaced. Components may include:

• inflow and outflow devices;

• trash racks and anti-vortex devices;

• valves, orifices, and aerators;

• concrete structures (such as the casing for a sand filter);

• pumps and switches;

• earthworks such as embankments and side slopes; and,

• mulches and vegetation.

While most SMFs will last for a long time with proper maintenance, a community or business should plan well in advance for replacing these facilities.
