Sand Filter
Description:
A sand filter is made up of a buried plastic liner filled with special sand and
gravel. After sewage passes through a septic tank, it enters a pump tank where it
is pumped to the sand filter. After flowing down through the filter, it is collected
and sent to the drainfield.
Function:
The function of the sand filter is to clean the wastewater to a high level before
passing it on to the drainfield. The coarse-sand filter creates an oxygen-rich
surface area for treatment. Microbes consume most pollution out of the water
s into the drainfield.
If sand filter has a pump basin, clean and pump when needed.
