What this license covers
- Drilling / construction: licensed to bore, case, complete, and plug water wells.
- Pump installation: licensed to install, repair, and replace well pumps, pressure tanks, and the piping between the well and the building.
- Monitoring wells: also licensed for environmental monitoring wells, not just water-supply wells.
- Geothermal loops: also licensed to bore the open- or closed-loop wells that serve a ground-source heat pump.
- Cleaning / disinfection: licensed to chlorinate, clean, and redevelop an existing well, the usual response to a bacteria result or a well that has lost yield to buildup.
- Deepening: licensed to deepen an existing well rather than drill a new one, an option when a well runs dry or the water table drops.
