These folks have integrity and I trust them completely. The difference between a great business and a mediocre one is how they respond when things don't start out right. In... this case, initially, things started out badly. An employee was making it very hard to have our well drilled and this was potentially going to delay the building of our new house. When I contacted John and his wife to complain, he personally looked into the matter, addressed it with the employee, apologized profusely to us, and got to our well drilling job as soon as possible. These folks have a lot of integrity!read more

Post Pump & Drilling drilled our well ahead of the scheduled date and through the job the drilling rig operator explained just what was goin on including what kind of rock... and other substrates the drill head was going through. He was very knowledgeable about the whole operation as well as the geology of the area and happily answered any questions. When John Post came on site again to help with the final stages of the operation there is another level of knowledge and willingness to explain and or answer questions. We really appreciate The whole Post team and there willingness to get our well drilled.Again thank you for your promptness expertise and hard work.D&Jread more

John, Clint and Josh are dedicated to their craft. I live in Haskill Basin which is notorious for fickle and difficult wells. They went beyond and above to get water to my... house. They have integrity and stand by their product. I will use them again and recommend anyone in need of water to use them. They are professional, courteous and fair. 5 starsread more

Clint and John drilled a well and installed a pump for us. From start to finish they were professional and honest. So much of what goes into to this you can’t see as the... property owner but they explained things in a way that made it easy to trust them and you knew they were doing what was best for your water. Any questions I had along the way were promptly answered even after I paid the bill. I wouldn’t hesitate to hire them again if I ever needed more

Post drilled our well June of 2020, and I couldn’t be happier with them. They’re very responsive, and informative. They spent plenty of time with us before they ever punched... the hole, and we felt very comfortable about the whole thing. We weren’t able to be there when they hit water, but they were very communicative and prompt. They’re very trustworthy, honest, and hard working. I recommend Post more

We spoke with several well drillers before we started, and we think we got lucky when we found John and Clint (and Josh) to do our job. They are experienced, very... knowledgable, hard working, honest, and pleasant to work with. (John has great stories). We had a tough project at our site, and these guys never let up; They wouldn't quit until they found us good water. I would highly recommend more

John and the Post Pump & Drilling team are great to work with! They obviously had in mind our success and satisfaction as property owners. They communicated with patience and... gave us options at several points as the drilling progressed. We highly recommend them in Lincoln County - or wherever in northwest Montana they're available to more

Clint and his family did a fantastic job installing a hand pump for our existing well. He also told us a few things to possibly look out for in the future given the age of... our pump. We'll definitely be using them again for the old pump replacement. Thanks for the hard work!read more

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.
