are used primarily for maintaining a constant
water level in the ground water. SUBGARD's
are totally self-adjusting and require
no maintenance. Place the SUBGARD in the
well above the submersible pump exactly
where the water draw down level is desired.
Allow the pump to run constant and the
SUBGARD will re-circulate the difference
between your pumps GPM and the wells yield,
sending exactly what the well is producing
to the surface. SUBGARD's maintain a cone
of depression and prevent contaminated
water from moving off site. Also, allowing
for easy removal of floating hydrocarbons
without water agitation.

the exact amount of water which the well
pump is producing 10 GPM. The well is yielding
only 3.5 GPM. In this application, the SUBGARD
will re-circulate 6.5 GPM back into the
well and allow exactly 3.5 GPM to continuously
go to the surface. If the well yield changes,
SUBGARD automatically compensates for the
