Nicholson Spring

Removed from system in 1993

The pumps and level sensors were removed in 1993

last used as a water source in 1989

Building demolished and cover construcetd in 2000

The spring flows up through a decomposed granite floor into
a basin consisting of a concrete wall and a wooden roof
approximately 18 feet long x 13 1/2 feet wide. The depth of
the basin is approximately 5 feet.

The spring was cleaned out in the summer of 1990. A drain
is provided around this spring to divert surface water and
shallow ground water away from the spring. There are no
developments or sewage hazards located upgradient of this
spring. The spring water is very clear and does not appear
to be directly influenced by surface water.

The spring was equipped with two submersible pumps. One pump
produced about twice the flow rate as the other pump. This
enabled the Association operational flexibility depending on
system demand. The 5 year drought preceding the 1993 inspection
reduced the spring's yield to about 5 gpm. It was observed that the
flow rate during the 1993 inspection was at about 8 to 10 gpm. The
spring basin was full during the 1993 inspection.
