From The Aspen Daily News (Andrew Travers):
The temporary drilling will be on the gravel parking lot for the city-owned Prockter Open Space, beside the Roaring Fork River and across Neale Avenue from Heron Park.
The city finalized an agreement with a driller for the site this week…
The final contract also allows for a drill-site footprint of about 3,500 square feet, up from the original bid’s estimate of about 400 square feet of surface infrastructure. The well itself is expected to be just 6 to 8 inches wide. The drill hole will be up to 1,000 feet deep…
Work is scheduled to take place between 7 a.m. and 5 p.m. on weekdays, and from 9 a.m. to 5 p.m. on Saturdays. In all, the project will take 19 to 31 days, including testing, with actual drilling taking place on eight to 10 of those days…
Based on a 2008 geothermal feasibility study, the temperature of local underground water ranges from 90 to 140 degrees. To heat or cool buildings with geothermal energy, 100-degree water is required. To generate electricity, the city would need water of at least 220 degrees.
