Ground Water Drilling - What we do?

Groundwater drilling is a process used to access groundwater stored in aquifers below the Earth's surface. Here’s an overview of the steps typically involved in groundwater drilling:

1. Site Assessment and Planning:

   • Hydrogeological Survey: Determines the best drilling site by studying the geology and hydrology of the area.

   • Permitting and Regulations: Securing necessary permits and ensuring compliance with local regulations.

2. Drilling:

   • Drilling Rig Setup: Positioning and setting up the drilling rig at the chosen site.

   • Borehole Drilling: Using a drill bit to bore a hole into the ground. The depth depends on the aquifer's location.

   • Drilling Methods: Common methods include rotary drilling, cable tool drilling, and auger drilling.

3. Casing Installation:

   • Casing the Borehole: Installing a casing (a steel or PVC pipe) into the drilled hole to prevent the borehole from collapsing and to keep contaminants out of the water.

   • Grouting: Filling the space between the casing and the borehole wall with grout to seal off the borehole from surface contamination.

4. Well Development:

   • Cleaning and Developing the Well: Removing drilling debris and fine particles to improve water flow. This can involve techniques like surging, jetting, or airlifting.

   • Pump Installation: Installing a pump to bring the groundwater to the surface.

5. Testing and Monitoring:

   • Well Yield Testing: Measuring the amount of water the well can produce (yield) to ensure it meets the required needs.

   • Water Quality Testing: Analyzing the water for contaminants to ensure it is safe for its intended use.

6. Completion and Maintenance:

   • Well Cap and Seal: Installing a well cap to prevent contaminants from entering and sealing the wellhead.

   • Documentation and Reporting: Keeping detailed records of the drilling process, including geological logs and well construction details.

   • Regular Maintenance: Periodically inspecting and maintaining the well to ensure its longevity and functionality.
