Water Well Drilling Services

Clear Heart Drilling

CLEAR HEART DRILLING 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.

Smaller Footprint

Our drilling rigs usually require a smaller area than traditional drilling rigs and support equipment.

In fact, one of our rigs is only 5’ wide and 13’ long and can still go to 100’.
Another rig – DR10K has a variable mast height and hence can get closer to power lines, safely.

The creation of a water well consists of several elements. After selecting the site to drill the well, the process includes drilling, sampling, installing casing, sand pack and seal. We take soil samples every 5’ which informs us on the type of formation and water saturation. From this information we can best decide where to place the well screen.

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

The contractor’s business address and state license number

A written proposal that details:
