About this Service
Open loop geothermal uses an on-site well as the circulating source. In Littleton, this is most applicable to valley or low-lying lots where wells access sufficient groundwater and where slope constraints make horizontal loops impractical. It can suit hillside homes that already have reliable well infrastructure.
Littleton’s foothill clay soils and sandstone bedrock introduce two main challenges: well siting on steep slopes and variable drillability through sandstone. A geotechnical review and a production test are standard to confirm sustainable flow and static water level. Water-quality testing should check for sediment, hardness, and organics; steep terrain often requires engineered discharge routes to avoid erosion and protect downslope properties. Heavy spring snowmelt and intermittent runoff also influence discharge design and installation timing.
Expect specialized pump integration and possibly a booster pump if static head or pressure losses are significant. Routine filtration maintenance and seasonal inspections are practical obligations. If the well cannot sustain the required GPM or if discharge land disposal is restricted, a closed-loop or mixed loop solution may be better. The service includes site evaluation, filtration and discharge recommendations, and a commissioning checklist documenting flow and treatment requirements.
