Pump Basin

Description:
Pump basins are generally plastic or fiberglass chambers housing a pump.
are usually 24" to 30" in diameter and 5' to 6' deep and can be for moving so
or liquids.
F
un
ction:
'Solids' or 'grinder' pump basins are usually installed because the plum
comes out in a
place where it was not possible to install a full sized tank. These
p
ump basins take in building wastes and pump them to a full-sized tank located
somewhere
else.
'Liquid' pump basins are installed as lift-stations to collect and transmit effluent
between tanks, or to a drainfield.
Maintenance:
Check pump basins yearly and clean or pump as necessary.
• Solids pump
basins are more prone to solids build-up and floats hanging up,
so check and clean often.
• Make sure floats swing freely and that cords are not tangled up.
• Visually inspect the basin annually for damage, leaks, etc.
• See Sections 1 & 2 for more information on protecting your tanks.
