Water Well Drilling Company

California well drilling companies must have the highest quality skills and knowledge to provide the state’s residents and businesses with well water.  DCA Drilling has experienced and professional well specialists who will be able to provide you with commercial or residential wells. DCA has been drilling since 1980 with different types of equipment.

Our specialty is drilling in hard rock conditions, from granite to a highly-fractured, volcanic formations. We use rotary air, which is basically drilling with a down-hole hammer, using only high pressure air with a little water, and no contaminants – no bentonite products.

Water is the most important commodity a homeowner can have. It should be protected from all contaminants for safe drinking as long as you own your home.  Choosing the right drilling company is important in achieving that.  We believe that protecting your well from oil and contaminants while drilling is crucial. That is why we use food-grade hydraulic oil in our drilling equipment and tools. We take pride in our work and deliver the best to our clients.

In the southern California mountain areas, the bedrock is made up of mostly fractured, volcanic material, which carries a lot of silt, that can wreak havoc in irrigation and household systems. We have created a special blend of silica sand, sized for very fine filtering, with .032″ slotted well liners. We install this silica material the whole depth of the well, between the liner and the earthen walls.

We have experience drilling wells in the Santa Monica mountains for 35+ years. We are fully equipped to tackle every job, from a simple domestic water well to a vineyard irrigation well to a complex, commercial water company well.

What our customers think of us:

Here are a few of many testimonials we've received from our hundreds of customers over the years...

Choosing a company to drill a well was difficult for me. There are many options and all are very expensive so it was important that I pick the best company right off the bat. I am so glad we went with DCA Drilling and I would highly recommend them to anyone. They have drilled two wells on my property now and both times they were extremely fair, professional & they got results. DCA really helped me from start to finish, they got the well permit for me, came out to the land to evaluate the most promising locations (both for water and for feasibility of drill access) and they carefully chose what was best for my project (streambank vs. bedrock, depth, etc.). Finally, they were really personal in their communication, they kept me updated every step of the way with progress, any adaptions in plans, etc. Our property is extremely dry and hard to find water on, so I truly appreciated all of the updates along the way. I do not think a producing well on our property would have been possible had I selected another driller.

My name is Carol and I live on the property where you drilled a well this week. I wanted to pass on my gratitude and thanks to the fellows who worked here and also to compliment them on the way they left the property. I was quite expecting to have to go in and clean up the site, but they have done a remarkably good job. Please pass on my thanks to them…
