Hi Guys
Small crisis at the family beach house. The water well is starting to subside and will eventually collapse into the borehole.
This is a typical Nica water well, which was hand dug~ 5 diameter and 14 feet deep. The side wall completion appears to be concrete, but I'm not sure. The well completion at the surface was just a simple brick enclosure around the diameter to keep out debris. The base of the wall is starting to slough, and the well will collapse. It was only built about 5 year ago. The pool water or rain water discharge may be facilitating the borehole collapse, but I'm not sure as I only can see pictures of the surface completing subsiding. FYI- we have never even used the water from this well, as Las Penitas has municipal water; however, I would like the option to obtain water from the well. Water from the well would only be used for non-potable uses.
Above is the background story, and now for my questions:
What types of electrical pumps are typically available in Nica?
Can these pumps small enough to be placed pipe (i.e grundfos pump/keck pump?).
I was thinking about brining down a peristaltic pump (i.e a surface mounted pump with a poly tube going down the pipe casing).
Can you buy slotted screen in Nica?
Slot size I'm not sure as to what I need as I don't know the grain-size of native materials. However, we may just make our own, so is 4-6 inch diameter sch 40 PVC available?
My plan was to backfill the 5 foot diameter well with 4 feet of gravel to create a void space for water collection. A slotted screen would be placed into the gravel connected to casing with a 3-4 foot riser coming out of the surface. After the gravel, the 5-diameter hole would be backfilled with soil (and the demo'd well blocks).
PS... it's the family beach house when it works, but seems to be mine when it needs repairsLOL!
