If you live in an area where you have frost it should be below the record frost depth, usually in the North it is a minimum of four feet. If you are running copper in the ground out west you can go substantially higher in the ground due to the lack of frost. I would recommend that you look at the building codes for your particular area as the requirements for each state and region can differ. Bed the pipe with sand below and above, 4-6 inches is a usually required above and below depending on ground conditions and relevant region of the country. You also want to make sure you are using the right grade of copper pipe made for direct burial.
Wells are naturally occuring and have natural spring water in them. In most wells the makers have dug deep into the ground and struck water. The water, in turn wells up (hence the term well) and fills the deep gap. To get water out of a well, first you need to construct a bucket lowering mechanism, lower the bucket, and pull it back up. There you have it.
There are a few parts to an answer. How deep is the water in your well? Is there sludge or sediment at the bottom of the well? How deep is this and how much is clean water? How long is your pump? How long is the motor housing? I just placed a 70cm pump, motor 35cm, in 250cm if clean water. 20cm of sludge. The bottom the motor housing was placed about 40cm above the sludge which means there is about 75 cm of clean water below the water inlet and 175cm of water above the pump. It will take many years for the sludge to rise and even in low water periods I should stay in operation.
This is impossible to answer without at least some site / ground investigation data to allow a preliminary geotechnical design to be undertaken.
A well is basically a hole drilled deep into the ground until it reaches an aquifer, which is a body of rock that transmits water. Wells with electric pumps pump the water through pipes to it's destination.
In rainy weather, the water table rises and ground water can sometimes "perc" up thru the ground and into your basement.It would pump the water out before it gets high enough to cause damage in your basement.
you tell me
Tulip bulbs should be planted about 6 to 8 inches deep in the ground.
Yes the water table is the level of water under ground .... it is currently very deep under water.
Plant tulip bulbs about 6 to 8 inches deep in the ground.
A 12-foot post should be buried at least 3 feet deep in the ground for stability and support.
i have the same question so when some one answers this call me
It is all the underground water, the water in soil and in (actually between) deep rocks.
Fence posts should be set at least 2 feet deep in the ground for optimal stability and durability.
A ground rod should be installed at least 8 feet deep for effective grounding.
Aquifers.
To effectively ground an antenna, you should connect it to a grounding rod using a copper wire. This helps to dissipate any excess electrical charge and reduces the risk of damage from lightning strikes. Make sure the grounding rod is buried deep in the ground and securely connected to the antenna.
depending on what area of the country you are in...16" should be safe enough. you should be careful of rock coming in contact with the piping as it could result in abrasive punctures over time.
