WALT BANNON DRILLING has always been family owned and operated.  The company was founded by Walt Bannon in 1936.  Walt's wife Juanita ran the office, and as soon as any of their children could take a phone message or see over a steering wheel, they were put to work too. 

Walt's son Dwight worked in the family business for 20 years before setting up his own drilling companies in northern California and southern Oregon. 

Walt and Juanita's youngest daughter Sunny helped in the office after school, weekends and summers.  After college in the early 70's, Sunny and husband Russell Duncanson returned to work in the family business.  In 1982 Russell and Sunny purchased the business allowing Walt and Juanita to retire after 45 years. 

The business was originally based in Mariposa County bringing affordable water to many foothill communities.  In 1969 the operations were moved to the town of Oakhurst to be more centrally located for their service areas of Eastern Mariposa, Madera and Fresno Counties.

Early on, Walt saw the value in accurate recording keeping and well log information.  Today the company hosts the most documented information on local wells and water systems with records dating to the early 50's.  These records are not only a valued source of information for individuals, researchers and government agencies, but a proven aid for determining well site locations and estimating well depth and flow.

In addition to the family members, the company employs several full and part-time employees,  who enjoy a group health plan, retirement plan, holiday and vacation benefits.

Russell and Sunny have owned and operated the company for over 27 years.  They continue to follow Walt's priority to CUSTOMER SATISFACTION and commitment to providing safe, reliable water at an affordable price.
