Dandelion was proud to partner with the Kingston Library in Kingston, NY on a geothermal system as part of a comprehensive renovation of a historic community library in 2024. This project required 20 boreholes of 500’ depth. Dandelion designed and drilled the boreholes, designed and completed the tie-in and designed and installed the manifolds.
This project required Dandelion to design a robust water and spoils containment system when the job was already underway. The test bore for the project, which was completed by another company, had indicated the boreholes would produce about 35 gallons of water per minute. However, when we began drilling, we quickly found the boreholes were producing in excess of 200 gallons of water per minute, and given the location of the library, it was paramount this water was adequately contained.
Our engineering team was able to quickly design a water and spoils containment system to allow the job to proceed without delay by bringing two holding tanks to site to contain water and spoils. We took the water draining from the holding tank and reinjected it into boreholes that had already been drilled. Once one holding tank filled with spoils, we switched to the other tank as the first had its contents disposed of, switching between them.
With the water situation thus adequately managed, the Kingston library project was completed on time and on budget.
