Viking Drillers Inc. - De Watering

Dewatering - The temporary lowering of the watertable for the purpose of construction, compaction and drainage. This is achieved by using various types of pumps, shallow wells, deep wells, eductor systems, well points and trenching systems to drain the groundwater from the soil.

After acquiring 17 years of dewatering experience with one of the largest dewatering contractors in the United States, William C. Holden established Viking Drillers, Inc. in 1983. VDI has grown to reputedly be the largest and highly respected dewatering contractor on the west coast. Our projects include small wellpoint jobs to multi-million dollar projects that include trenching and dewatering wells, like the Sacramento County Northwest Interceptor. VDI has worked closely with owners, consultants, engineers, contractors and governmental agencies to solve diverse dewatering problems.

VDI maintains a full line of dewatering equipment for rental, including submersible pumps, centrifugal pumps, vacuum pumps, diesel sound attenuated generators, auto-transfer switches, large double wall fuel cells, junction boxes, s/o electrical cord, 60 to 3500 gallon sand sediment tanks, well casing, pvc discharge piping, and Yellowmine pipe. All equipment is maintained inhouse. Our own employees do the repairs and testing before the equipment is sent out into the field, ensuring that our customers have the most reliable equipment available.

VDI is also a manufacturer's authorized distributor and service center for several name brands of submersible pumps and equipment. Name brands include: Multiquip, submersible pumps and sound attenuated diesel generators, Prosser, submersible pumps, Grundfos, turbine pumps.

VDI uses Bayshore Systems state of the art track mounted Lodrils exclusively. The rigs range in size from "Pee Wee" a low overhead machine w/ 9'6" clearance, 30,000 lb. to 80,000 lb. excavator style machines and "Moe" a 105,000 lb. machine capable of drilling 15' diameter holes.

VDI's trenching division utilizes three trenchers, all with their unique capabilities, to trench up to a 36" wide trench 23' deep, install the trench drain tile and a gravel envelope all in one pass. Horizontal dewatering has become an invaluable tool, when above ground equipment would be undesirable, the ground water can be extracted more effectively using this process than wells. We can also install permanent agricultural drainage systems.
