Your Complete Guide To Nested Wells Installation, Casing, and Borehole
Are you looking for information regarding nested wells?
Did you know that there are over 2.78 million trillion gallons of groundwater contained within the Earth?
Well, it’s true. As freshwater, this groundwater is filtered and used for drinking, bathing, and many other day-to-day functions.
To ensure that it is safe to use and that no toxins get into the soil surrounding it, monitoring via wells is necessary. Sometimes nesting wells are the best way to go. Here, we’re going to talk about how nesting wells are constructed, installed, and used so that you understand the importance of drilling one on your property.
The Basics of Nested Well Construction
Wells are intended to monitor groundwater’s pressure, chemical makeup, and biological properties in a single area of the ground. They usually go down to monitor the flow of fluid at a specific single depth within the earth. However, in some situations, it will be necessary to monitor the water pressure at multiple depths beneath the same surface area.
This is where nested wells come in. These wells are constructed with two or more casings in the same borehole. Each of these casings is separated by a grout seal so that they don’t contaminate each other if chemicals like landfill gas get into one.
How Are Nested Wells Installed?
To install a nested well, professionals will drill into the ground in the same way that they would create a single well. They then will drill further past what would have been the bottom of the borehole.
The entire hole needs to be wide enough to accommodate all of the well casings that will go into it when they are completed. There will be one wide casing that fills the entire hole and smaller casings that fit within it and monitor water and soil at different depths.
To separate each part of the casing, grout seals would be installed at each of the points that need to be measured. This will give you more accurate readings of deeper wells as well as shallow ones.
What Challenges Might You Face?
One of the biggest difficulties in installing a nesting well is that casings become more difficult to construct. Since each well layer needs to be completely isolated from the others, they need additional filter packs topped with bentonite seals. This is what ensures that they don’t leak into each other.
Another challenge may be accidental holes in the sealing. Ensuring that there are no voids requires constant maintenance and careful monitoring of the installation process.
However, these challenges are not something that you should be worried about. Our highly-trained professionals are skilled and experienced, and therefore you won’t need to worry about potential problems.
