SUBJECT: Pumping test - Talus West Subdivision
On Friday, December 13, 1974, the pumping test for Lot 3, Block 3, Talus
West Subdivision, was run in conjunction with Tryck, Nyman & Hayes. The
test well was located sixty-nine feet from well number one and one hundred
and five feet from well number two. The observation well, number one, had
twenty-seven of water in it and total depth of one hundred and sixteen
feet. The test well was pumped at 2.7 gpm, for three hours and thirty
minutes and then at the rate of 3.5 gpm, for two hours and thirty minutes.
There was no ~appreciable change in draw on well number one during the
entire pumping period. This would indicate that the eleven hundred and
sixteen gallons of water drawn from that test well in the six hour period
did not move the circle of influence outward to test well number one.
In addition we discussed the well situation in Talus West Subdivision with
Mr. Wright, a builder in the area and a former well driller. He indicated
that last August he had run his well for a two week period at an estimated
rate of 5. gpm, and had not depleted the water level in his well.
It would indicate that tentatively sufficient water were available in the
Talus West Subdivision, providing that the wells were properly developed
with at least sixty-nine feet of space between each well.
