Some frequently asked questions (FAQs) about water well drilling include:

There are many factors why groundwater exists; the biggest is geologic formations. Without the right geologic conditions groundwater will not occur. A field representative needs to have a clear understanding of the regional geology to provide the best possible chance to find groundwater. "Well Dousing can't change the geology."

On average in the northern coastal California area, up to 50 miles inland. Water Wells can be drilled on average to a depth of 140'– 240'. Some water wells are shallow less than 50' and some are deep water wells over 400'+. On the shallow water wells the sanitary seal determines the minimum depth this in turn will effect water well costs.

On a residential water well for a single family home the yield can be as low 1 GPM (gallons per minute) that works out to be about 1400 gallons of water in a 24 hour period. If you have extensive landscaping, the yield needs to increase significantly up to 10 – 15 GPM. Ultimately the end use of the water will dictate your GPM needs.

Most private water well construction takes 1-2 Days to Drill, case and filter pack. The final stage is the sanitary seal, this is put in between the drilled bore hole and the casing to keep surface water from entering in the well. This has to be scheduled with the Department of Environmental Health for inspection and can take a few days to coordinate.

Since modern water well drilling rigs are more efficant, the room needed for drilling rigs and it's ancillary equipment are less than years past, mostly 12'-15' wide and clear of overhead obstructions will do the trick. Consult with the field representative for your particular needs.

Usually this is a very simple process with some basic information, (APN, site address, site map with well location). Some water wells located in the coastal zone can take longer.
