Job Task Planning and Organizing
  • Water well drillers follow established drilling and well development procedures, with variations only in drilling sizes and time required to drill and develop water wells. They are assigned drilling jobs daily by supervisors and continue until they are completed. Self-employed water well drillers select and organize their own jobs but they have similar job task planning and organizing requirements. They are responsible for organizing their daily tasks. Water well drillers organize job tasks for labourers and apprentices. They may rotate job task assignments to maintain workers' skills. In addition, they may monitor apprentices' activities and assign tasks to meet their training and development requirements. (2)

Decision Making
  • Choose locations for wells. Consider how easy sites are to access, how far they are from septic drainage fields, buildings and roadways and how their elevations differ from points where the water is needed. In some cases, ask customers and supervisors for approvals to drill in new locations. (2)
  • Select types of equipment to complete drilling and water well installations. Specifications in hydrogeological reports may guide your decision but other factors such as mud losses, types of bedrock, customers' water requirements, cost and past experience are critical factors in equipment choices. You may seek customers' approvals before purchasing equipment such as pumps for water well. (2)
  • Select drilling methods and techniques. For example, choose drilling muds and sands. Choose drill sizes and speeds, and choose to reduce drilling speeds and hole diameters when too close to aquifers to avoid drilling past them. (3)

Problem Solving
  • Drilling sites are hazardous. For example, steep land slopes make stabilizing equipment difficult. In some cases, speak with supervisors and other water well drillers for advice and suggestions on stabilizing the slope and the rig to ensure safe drilling. You may seek supervisors' approvals before drilling. (2)
  • Encounter dry holes when drilling. For example, no water is found after drilling to depths where water would normally be found. In some cases, discuss alternate well locations with supervisors and customers, review hydrogeological reports and ask for advice from hydrogeological engineers before continuing. You may employ the services of dowsers. (2)
  • Face equipment breakages and malfunctions which reduce water flows at existing wells and prevent the drilling of new wells. For example, the pumps are not working properly and customers' cisterns are running dry. Consult operating manuals for service and repair information. If necessary, arrange the lease and purchase of alternative equipment. (2)
  • Experience workplace accidents which result in injuries and fatalities. Inform supervisors, shut down equipment, assess injuries and administer first aid. If necessary, call emergency services to request medical advice and aid. (3)
Back to Top

Finding Information
  • Locate information about drilling and well construction jobs. Find information about initial drilling methods, mud mixtures, hole diameters and geological formations by reading well records, hydrogeological reports and by consulting supervisors and more experienced drillers. (2)
  • Find information about drilling and water well equipment by studying flowcharts, assembly drawings and operating manuals and speaking to other drillers. (2)
Back to Top

Critical Thinking
  • Judge the suitability of labourers and apprentices when hiring drilling crew and assigning tasks. Review résumés and apprentice training plans when hiring. Consider personal observations of the performances of the workers when assigning tasks. (2)
  • Judge the safety of job sites. Inspect work sites using safety criteria such as proper clearances from hydro wires, adequate identification and containment of mechanical and chemical hazards, and proper placement and set-up of equipment. (2)
  • Evaluate the quality of aquifers. Use criteria such as water clarity, yields per minute, static water levels and water recovery rates during and after pumping. In addition, consider the depths at which wells are drilled into rock beds and quality of the rock chips produced during drilling. (2)
  • Judge the condition of drilling and water well equipment when completing daily vehicle inspections and performing general maintenance tasks. Inspect equipment visually and take measurements, which are compared to specifications to determine repair and maintenance requirements. (3)
