Efficient water treatment loop drilling for sustainable heating and cooling

Cole Bros Well Drilling provides water treatment services throughout Oceana County and surrounding areas — supporting ground-source heat systems with expert borehole drilling and loop installation.. water treatment systems offer energy-efficient heating and cooling by exchanging heat with the ground; correct drilling and loop placement ensure system efficiency and longevity.

Types of water treatment installations

Cole Bros specializes in vertical borehole drilling in the Pentwater region where properties often require compact loop fields.

Vertical boreholes

Common in smaller lots; deep, narrow holes that accommodate U-shaped loop piping.

Horizontal loops

Trenched loops near surface for larger properties with adequate space.

Our water treatment process

System design coordination

Work with HVAC engineers to size the loop length and number of boreholes based on heating/cooling loads.

Site assessment

Evaluate access, surface conditions, and proximity to utilities or features.

Permitting

Assist with local permits related to drilling, grouting, and land disturbance.

Drilling

Use rigs selected for vertical borehole drilling to reach specified depths with minimal disturbance.

Loop installation and pressure testing

Install closed-loop piping, test for leaks and pressure integrity before backfilling.

Grouting and sealing

Use thermally conductive grout to fill annular space and secure the loop for optimal heat transfer.

Documentation and handover

Provide as-built records for performance verification and future maintenance.

Materials and techniques

  • High-density polyethylene (HDPE) loop piping for durability and thermal transfer.
  • Thermally enhanced grout to improve heat conduction between soil/rock and loop piping.
  • Thermal conductivity testing when required to refine borehole sizing.
  • Pressure testing to ensure loop integrity prior to commissioning.

Why grout matters

Grout fills the annulus between borehole wall and loop piping. It stabilizes the borehole, prevents surface water migration, and improves thermal contact with surrounding formations. Thermally enhanced grout increases system efficiency and is essential for long-term loop performance.

  • Considerations for homeowners and developers

    • Water treatment systems have higher upfront costs but lower lifetime energy costs.
    • Accurate load calculations and ground thermal assessments optimize system size and reduce overdrilling.
    • Proper site planning avoids interference with utilities and preserves landscape features.

  • Environmental stewardship and regulatory compliance

    water treatment sites are sensitive to groundwater protection. Cole Bros uses best practices to prevent contamination, ensures grout integrity, and follows applicable environmental regulations during drilling and restoration.

  • Long-term performance and maintenance

    Closed-loop water treatment systems are durable with minimal maintenance. Periodic checks of the heat pump system and loop pressure monitoring are recommended. If issues arise, Cole Bros provides diagnostics and repair for loop integrity or borehole concerns.
