Dan Gare has experience drilling throughout B.C., from Terrace to Osoyoos and from Whistler to Radium. We primarily work in and have extensive knowledge of the Okanagan, Columbia-Shuswap and Thompson-Nicola areas.
 
     
 
  Sand and gravel wells (6", 8" & 12" diameter) are drilled with our modern air rotary rig. The steel casing is driven down with a casing hammer as the well is being drilled. When water is found in sand or gravel, stainless steel screens are installed below the bottom of the casing and then developed to keep the water free of sand. We install the correct slot size of screen for the sand found in the well, from .004-slot (finer than a human hair) to .250-slot (for coarse gravel). The screen allows as much water as possible to enter the well while keeping the finer sand and gravel out. Multiple screens can be installed in the well to increase the intake area thus raising the production. If the well is pumped at the rate recommended on your well log, you should have no problems with sand in your water.
 
     
 
  Bedrock wells (6" & 8") are drilled with a special down-hole hammer into the mountain rock. The water comes into the well from cracks and fractures in the rock (just like the seepage seen from the rock faces along the highway). Bedrock wells will have casing in the upper part of the well, through the overburden, and an open hole drilled in the bedrock. Bedrock wells are drilled to a depth that will give sufficient water yield alone or in combination with storage in the borehole of the well. Although some bedrock wells only produce a small amount of water, with water storage in the well borehole there is usually enough water for household use.
 
     
 
  Pressure fracturing is a procedure we are able to use in the bedrock wells that we drill, in some cases the yield can increase from about 1/2 gallon per minute to double or more. Water under extreme pressure is forced into the bedrock cracks, opening the cracks somewhat and increasing the water flow. This does not work in every type of bedrock formation. Through years of experience we have gained the expertise to know if pressure fracturing would be successful.
 
     
 
  Flowing artesian wells are wells that overflow at the surface. When drilling a flowing well, it is important to control the flow. Proper construction prevents the waste of water and flooding or permanent waterlogging of the surrounding lands. We first install a larger diameter surface casing down into the clay layers and then drill the casing for the producing well inside of the surface casing. The surface casing contains any water that might be forced up, by the static water pressure, around the production well casing, so that there is no flooding of surrounding areas.
 
     
 
  Geothermal / GeoExchange drilling for heat pump loops, is an option for heating the house and hot water. If we drill a bedrock well which does happen to be dry, the drilled borehole can be used to install a loop for a geothermal, earth energy heating system. These types of heating systems are becoming more desirable to save on the use of fossil fuels.
