Horizontal Water Well Drilling Services


is a respected water well drilling contractor in Northern California.

Property owners and consultants have given high praise for our professional, skilled and conscientious people.

Our drilling rigs are designed using 11” hollow stem augers. These powerful rigs drill wells up to 130’ deep. We require no drilling fluid and hence mainly soil cuttings are exiting from the borehole. Thus not such a big muddy mess.

Why chose horizontal Water Well?

Property owners may chose a horizontal for several reasons.

  1. No success finding water with a vertical water well drill rig.
  2. Owners property or neighboring property has spring activity.
  3. Want the quality of spring water as oppose to deep well water which may have high mineral content, e.g. iron.
  4. Remote site where access is a problem and must drill with a track rig and track support vehicle. We do have track vertical rigs, but they have depth limitations and cannot drill in hard rock.

How Much Water Is Needed?

Wisely planned, dependable water well can supply all the water you need now and into the future. A rule of thumb is to allow between 75 to 150 gallons per person per day. You need to take into account the peak demand, for example when there may be extra guests for holidays and weekends. Outside use of water can pose much greater demands. You need to calculate the required well yield if your well is needed for additional water uses such as swimming pools, irrigation, fire protection, heating & cooling, etc.

Low-Yield Wells

Some sites may not be capable of producing the amount of water normally expected for domestic supply (4-10 gallons per minute [gpm]). However, with an adequate storage tank, a well producing as little as one gpm can be sufficient for domestic needs. There are 1,440 minutes in every day. If a well produces one gpm, 1,440 gallons can be pumped in a storage tank daily.

Assuming that each member of a family of 4 uses 75 gallons per day, that’s a total of 300 gallons. Total consumption for the entire family is less than 21 percent of the stored water. The well would be required to produce water for a total of only 5 hours a day in order to replenish the tank.

Deciding on a Water Well Contractor

The National Ground Water Association warns not to base your selection of a well contractor on price alone. Your well system is permanent and future changes may be much more expensive in the long run. Make sure that bids and estimates are “Apples-to-Apples” and that they are for comparable quality materials, service and guarantees. The lowest bid is usually not the best value. Be sure your contract contains:

CPier – Eureka – Homboldt County
