Below you will find 28 questions and answers from getting started with well drilling, about wells and how they work,  what you need to do and details about the pumps.

Q - Where are we located?
A - We are located in Goldendale, WA.  We service much of South Central Washington. Please view our Service Map.

Q - What exactly is a drilled well?
A - A drilled well consist of a hole bored into the ground, with upper part being lined with casing. The casing prevents the collapse of the borehole walls and with a drive shoe or grout seal prevents surface or subsurface contaminants from entering the water supply.

Q -How long will my well supply water?  
A - Wells drilled 40 or 50 years ago still produce water and are in use every day.  The wells which have been abandoned usually have been abandoned because the steel casing has rusted out, not because of lack of water.  The PVC casing used today will last indefinitely, and wells drilled today should still be producing water many decades from now.

Q - I've heard of problem wells, how can I know my well will be good?  
A - Wells drilled 20 to 30 or more years ago were usually not constructed to the kind of standards used today.  Unfortunately, there are still contractors today who don't put out the effort or material to complete wells to the standards that are available today. Choosing your contractor carefully is the key to getting a well you will be happy with. You may want to check the Well Contractors creditability before hiring. Please view our Testimonies. We also have not had any unsatisfied customers.

Q - Do I need a permit to drill a well?
A - Yes,  Washington requires a permit to construct a well. Washington: $200.00 to the
Dept. of Ecology.  We will gladly handle the paperwork on our customer's behalf. To view

Q - How do I decide where to drill?
Several factors determine where to drill:

1- Legal distance from both property lines, septic systems and other utilities.
If your contact your local Board of Health or Building Permits office they will be able to tell you their specific requirements. You will need to have your property perked for the your septic system before having your well drilled.
Terrain & accessibility to your well site now and in the future.
Location of future or present home and other out buildings will affect where you want your well drilled.
In some areas where water isn't abundant, witching may increase the odds of finding water, by narrowing your search for a drill site.

Q - When should I have my well drilled? 
A - If you are building a house, the well should be put in first.  Your building contractor will need water for a number of things during the construction of your home.  It is best to have the well a head of delivery for manufactured homes as well.

Q - What do I need to do before you drill and what will I need to do after your done Drilling?
A - Every installation is different, depending on local codes and state laws can make a difference on how much preparation and finishing touches will need to be done by us or subcontractors. Most homeowners already have local contractors that they use and we can work with them or if need be we can subcontract leaving you with very little to do.

Q - What determines how deep my well could be?
A - Well Drilling is very unpredictable, there is no exact science of locating the water before you start drilling. However if you consult with your immediate neighbors, it might give you a general idea of the average depth of wells in your area. Also State or Local Regulating agency may have records on file of wells in your neighborhood.

Q - When drilling a well, how do you know when you have reached water?
A - We keep an extensive database of all the wells. From that information, we can determine your neighbors’ well depths and static water levels. We also review details regarding the construction of those wells. This information can be very helpful when we bid and construct your well. In addition to the database, and even more importantly, our well drillers’ experience will help make the final decisions that result in a successful well.

Q - How much water can I expect from a well?
A - Most of the wells we drill can supply more water than the customer needs.  There are areas, however, where water resources are limited or not present.  Give us a call and we will be glad to tell you what you can expect at your location.

Q - How much water will I need?
A - Depending on what the demand in the household is would depend on how much water is needed. For example, is there Irrigation, hot tubs, multiple bathrooms, and other utilities that demand water? All these items make a difference from home to home. The
NGWA suggests 7 GPM for the average home. Most towns require 5 GPM which is fairly good as a minimum. Several Irrigation contractor look for 10gpm for Irrigating alone.  But the best thing to do is discuss your water requirements with us and we can compare your need with records in your area.

Q - Can you give me some idea of average water consumption?
A - For overall daily consumption, checks of families of various sizes in different parts of the country indicate 100 gallons per day per person is a very good average. In addition we've provided the following table to help you better understand common water usage:


Gallons per usage

Flow rate (gpm)













Kitchen Sink



Laundry Tub









Water Softener

up to 150


Garden Hose 1/2"



Garden Hose 3/4"






Q - How much will my well cost?
A - We can tell you about what your well will cost by the other well depths in your area. How big of a pump you need to accommodate  your needs or the depth of your well factors into the cost. We cannot give you an exact price but only an approximate.

Q - Is financing available for well drilling?
A - Yes.  Banks and Savings & Loans regularly make loans for water wells as home improvement loans.  This method of financing offers the best terms available.

Q - Is my well water safe to drink?
A - Yes!  Well water is usually the safest source of drinking water available.  Most deep well water entered the ground hundreds or even thousands of years ago, before there were any man made chemicals around. Well water is not as vulnerable to pollution, contamination and disease as the sources of water where municipalities typically get their water. In our area certain bacteria's are found but easily treatable. Before your well is used a water sample will need to be tested through the local Health Department.  For further water testing, outside labs can test your water. We have a list to view of those testing labs in our Links Page.

Q - How much mess will the Drilling Rig make of my yard?
A - If it is a new construction and the landscaping has not been completed then cleanup is simple. When drilling in established areas some minor landscaping may be needed.  Location for your well is something to consider for further possible well pump repair, which will take a large truck to pull out.

Q - How long does it take to get my well drilled?
A - Most wells in this area take two days to a week or so, depending on depth and other variables. Of course the sooner you call the sooner we can get started. We can usually get to your well started in a timely manner.

Q - What is a casing and how much will I need?
A - Casing is a metal pipe designed to sheath the borehole. Casing is installed until rock, water or consolidated formation is reached. A minimum of 18 foot seal is required and sometimes hundreds of feet, depending on the depth of your well and how stable the ground stays while drilling.

Q - What is a PVC liner and do I need one?
A - A PVC liner is similar to casing only made from poly vinyl chloride, a very hard form of plastic and usually is perforated and installed from inside the casing and to the bottom of the well. This helps eliminate anything ever falling in or collecting around the pump. It is also sometimes used to install PVC screens.

Q - What is a well screen, and would I need one?
A - There are several varieties of screens made up of either stainless steel or PVC. Screens are primarily used in wells that contain sands and/or gravel, the screens hold back, or filter the formation, while allowing the water to move freely through to the pump without sediment. Whether one is needed or not, is dependent on the formation drilled, and the well's tendency to pump sand or grit.

Q - What is a surface seal?
A - A surface seal is typically bentonite or a bentonite slurry, a form of processed clay; It is placed in the oversized borehole around the casing to a minimum depth of 18 feet to protect the well against possible surface contamination.

Q - How do we determine what pump is good for my well?
A - Determining the amount of water available in the well; through drilling, or test pumping, accompanied with the amount of water the customer needs; allows us to select the correct pump. This eliminates over-pumping the well and reduces cycling time of the pump, which greatly increases the pump and control's longevity.

Q - What brand of pump do you install?
A - We can, and do install most major brands of pump on request, but we primarily recommend and install both Flint & Walling, Aqua Duty, and Constant Pressure Systems. We have found these pumps to be exceptionally reliable, efficient and affordable throughout the years.

Q - Do I need a pump house?
A - A pump house is designed to house the necessary components to run the pump system. If you have adequate room, the controls and pressure tank can be placed inside your home, either in the garage, basement or utility room; your shop or in a pit eliminating the need for a pump house. The controls and tank need only be protected from the elements, primarily freezing.

Q - What is a pressure tank?
A - A pressure tank is what stores your water and delivers it to your faucets under pressure until the pump comes on. At that point the pump is doing the work until the tank can be refilled and allow the pump to shut off to let the well recover.

Q - What is a pit less adapter?
A - It is a threaded metal connector that allows you to connect your service line directly to your pump pipe through the well, below the frost line.

Q - What is the difference between an air-test and a certified test pump?
A - An air test is the method of injecting air into the well to force the water to the surface for measurement. Although effective, this method sometimes produces a GPM amount more or less than an actual pump test. A certified test pump is an accurate measurement using a pump to pinpoint the exact GPM and amount of drawdown in the well, when in use. Most county regulations require a certified test pump prior to issuing building and septic permits. Most Lending institutions also require a certified test pump.
