About this Service
Open loop geothermal systems use groundwater from an on-site source instead of buried closed loops. In Lakewood, open loop is most appropriate for valley-floor properties or ranch lots that already have a well and allow a compliant discharge path. It can reduce yard excavation on properties where drilling or shallow wells are feasible.
Lakewood’s foothill geology and granite outcrops make well siting and drilling techniques more important than in flatter parts of the metro area. Expect a pre-drill geologic review to determine whether fractured bedrock will require specialized drilling rigs or deeper wells. Water-quality testing for silica, iron, and suspended solids is common near foothill sources; filtration and corrosion control may be required to protect heat exchanger tubing. Snow and seasonal access windows also affect scheduling for drill crews and tie‑in work.
Practical limits include well yield versus system GPM needs and routing discharge away from slope erosion areas. When wells are shallow or fractured bedrock reduces yield, the project may need a supplemental pump or a closed-loop alternative. The deliverable includes a site evaluation, recommended pump and filtration equipment, an itemized estimate, and a commissioning checklist that sets expectations for performance and routine maintenance.
