I had my second well drilled in the summer of 2013. The first well began yielding less water than was needed for the irrigation system. Even though the driller attempted to blow it out, he was not successful. It was believed the PVC screen sections had become partially clogged with sand over its 35 year life.
The new well was drilled only 35 feet away and is at the same exact depth as the original. It has and continues to yield the watering requirements for the irrigation system. I closely monitor the draw down and it is the same now as the day it was drilled.
The new well is 151 feet deep
The static water level is 111 feet
The pump hangs 135 feet from the top of the well casing
Drawdown of water level is approximately 2 feet during operation
I started irrigating in late March of this year. The system runs daily unless we have had adequate rain, at which time it automatically shuts off until the sensor allows the system to run once again.
About 3 weeks back, I noticed the sprinklers were not running one morning. After close examination, I found that the 100 mesh screen on the filter was caked with what appeared to be a very thin layer of clay. (Note: this is a sand well, but they did go through a layer of clay when the well was being drilled). I cleaned the filter and all has been OK up until today. Today, the filter was once again caked with a very thin layer of what appears to be clay. Does this mean anything?
I do recall this happening once last year. This well and the initial well have always had a small amount of very fine sand mixed with the water. This is why I utilize a filter ............. to keep sand from getting into the irrigation sprinkler heads and valves. I check the filter at least 3 times a week. If I were asked how much sand is being pumped DAILY, I would guess about 1 tablespoon. And that is after pumping continuously for 6 hours and pumping approximately 3,600 gallons of water.
However, the clay coating on the filter twice this year, which essentially plugs the 100 mesh screen, has me concerned. Or is this a concern at all?
Thanks for helping!
