How to Handle a Gaseous Well

In some areas well water contains gases which must be al-
lowed to escape before the water is used. This can be done
as shown in Figure 9.
A good way of delivering gas-free water is to suspend a pipe,
closed at the bottom and open at the top, surrounding the
suction pipe. Since the gases rise in the well casing, the
water sucked down through the pipe and into the suction
pipe is free of gas. This type of well must be vented to the
outside of any enclosure.
