General Questions

Here are some frequently asked questions (FAQs) you may find useful as you consider adding a water well in your residential or commercial property.

A popular phrase used to describe a water well is “Just the tip of the Iceberg.” What you see above the ground known as the well head is just a small part of the actual well.

The well head is durable PVC that keeps debris out of the well. A smaller PVC pipe attached to the head protects the electrical that powers the pump.

Then we start to go into the components of the well that you can’t see such as the casing and the pump. The casing allows water to flow up from the aquifer (groundwater) and reach the pump.

The pump acts like the heart of the well, pumping water from the casing and pushes it into the home.

At the bottom of the well lies the stainless steel screens and sand to provide additional filtration for the groundwater.


Although Mosier Well has several sizes of drilling rigs to accommodate different access issues, A 30-foot truck that is about 8 feet wide is a good size to prepare for. The well is drilled where the trailer hitch would be. Additional room may be required on both sides of the rig for access to controls and supplies. In some cases, home owners end up choosing to have the well drilled in their front yard for the best outcome. They can chose later on to disguise it with a false rock or yard décor if they find the well cap not aesthetically pleasing.

We use mats that displace the trucks weight evenly, which avoids sinking and damage. We also dispose of our excess fluids off of the property.

We always aim to please but are not able to control the groundwater underneath you. It truly depends on the area in which you live.

The answer could be something as simple as a plugged softener, whole house filter or faucet aerators. Or it could be as complex as a bad bladder tank, a hole in the water service line or even plugged impellers in the pump. Mosier Well will not only diagnose and solve your well issue but explain how it happened and how to avoid it in the future.

Most commonly we find sand in the water when the bladder tank or check valve have failed and are causing the well to surge water back and forth, thus allowing sand to be pulled through the screen. Although that may be a popular cause of failure, there are many other factors for no 2 wells are the same.

Irrigation Wells

When considering a lawn sprinkler system or expanding landscaping to a new section of the yard, few people know how much irrigation well can save homeowners money in the long term while protecting their landscaping investment. Below you’ll find a list of frequently asked questions we get about irrigation wells.

An irrigation well is very similar to a well-drilled to provide water to a home, except the water is hooked up to a sprinkler system or faucet for use outside the home. Because you aren’t using water from the municipal system, it will not be charged on your water bill, saving you considerable money. These wells must be installed by a professional well drilling service, but you can talk to your landscape designer or sprinkler system installer about how best to add irrigation well as the source.

If you are going to drill an irrigation well,

  • You must have enough room in your yard to support the heavy equipment needed to do the work. This equipment needs a way to get in and out of the property, as well.
  • Once the feasibility is established, think about where it would be located. The farther from the home and the irrigation system, the more expensive the well, since additional excavation and pipe will be needed for the connection.
  • Also, think about whether you will want to expand your home. Wells cannot be moved so make sure it is not located in a prime spot for building a new room onto your home.

Each community and the state have different regulations regarding well drilling, but most require certain setbacks from property lines, buildings, and wetlands.

Before calling a well drilling company:

  • find out whether there are any other wells on your property or within 100 feet of your property
  • research locations of nearby wetlands, streams, and ponds

This will help you answer some of the questions the well drilling company will have.

Irrigation wells can be one of two kinds:

  1. A shallow well, also known as a dug well, is less than 50 feet deep. It draws water from groundwater and can provide adequate water for a reasonably sized garden.
  2. Bedrock wells are drilled deep into the ground and draw water from aquifers.

Both can provide the needed 10 gallons of water per minute.

Drilling a well can cost between $8,000 and $15,000, depending on the location. However, a homeowner can recoup much of that cost by saving money on water bills. It’s not unusual for an owner to shell out more than $1,000 a summer on a water bill. Irrigation wells substantially cut that cost, helping to defray the cost of installation.

Irrigation wells draw a relatively small amount of water for use in your yard. The water is returned directly to the ground, helping to restore groundwater reserves. The water is also untreated, unlike water from your municipal system, which prevents adding small amounts of chemicals into the environment.
