FAQ's About Water Wells
How long does it take to drill a well?
Drilling a well can take anywhere from an afternoon to a few weeks, depending on the depth and hardness of the formations. We try to drill about 100-150 feet in a day. When we drill into an acceptable aquifer below the state-required surface seal depth, we complete the well and the well is ready for a pump.
What happens if there is no water within the depth indicated on the estimate?
We strive to maintain transparent, well-informed communication with our customers. At times, in glacier country, an aquifer shown in local well logs is not found. When it happens, we maintain open communication with our customers and together we make an informed decision for moving forward. The most common approach is to review additional well logs and see if the formations match to see if there are indications of aquifers at a lower depth. Drilling deeper is often more cost effective than moving into a new location, but that is determined on a case by case scenario.
What is the size of casing coming out of the ground?
Residential wells typically use a 6-inch steel casing. Other sizes, while uncommon, are 4-inch and 8-inch.
Where is your casing made?
We purchase domestic, made in the USA casing. Domestic casing, in our experience, is more durable, and of higher quality than casing that is sourced outside of the United States.
How close to a drain field or sewer can a well be drilled?
Montana State law requires that a well be no closer than 100-feet from drain fields and sewers.
Why is my well water discolored?
Groundwater coming out of new wells typically have a discoloration, like a reddish or orange color. The discoloration is caused by sitting water inside the steel casing. The discoloration will go away with time and use.
We advise people to run a sprinkler until the discoloration clears up. Sometimes it can take up to a year of frequent use for the water to continuously come out clear.
