Nettle Creek Hydro

Roaring Fork Engineering served as town engineer and owner’s representative for a small hydropower plant that generates renewable energy for Carbondale’s Nettle Creek Water Treatment Plant. The plant sits on Forest Service land and was built with minimal site disturbance.

Roaring Fork Engineering served as the Town of Carbondale’s engineer and owner’s representative for the construction of a small hydropower plant along Nettle Creek, adjacent to the town’s Nettle Creek Water Treatment Plant. The goal was to generate renewable energy to help power the treatment plant.

Challenges & highlights

Moving this project from feasibility to implementation required significant field engineering and field changes. Our team reconstructed a spring infiltration gallery that collects water into the main supply pipe for the treatment plant. We then built a small takeoff from that pipeline to the hydropower unit, which discharges back into the same pipeline. Water is diverted to generate electricity and then continues on to treatment, so there is no loss within the system. Field fabrication of the hydropower system was also required due to equipment conditions.
The site is on Forest Service property, so disturbance had to be kept to a minimum to limit environmental impact. The setting below Mount Sopris is also one of the most scenic of any project we have completed, especially in the fall.

The results

The Nettle Creek hydropower plant is operating and generating renewable energy that powers the Town of Carbondale’s own water treatment system. Water is diverted through the turbine and returned to the supply line, so the town produces clean electricity with no loss to its drinking water system. The project reduces the electricity Carbondale buys from the utility and advances the town’s renewable energy goals, all within a Forest Service setting that required minimal environmental disturbance.

Location: Carbondale, CO

  • Scope covered construction observation and implementation as the Town’s engineer and owner’s representative
  • Spring infiltration gallery was reconstructed to collect water into the main supply pipe
  • A takeoff from the pipeline feeds the turbine, which discharges back into the same line, so no water is lost
  • Hydropower unit required field fabrication due to equipment conditions
  • Plant is operating, reduces electricity purchased from the utility, and advances the town’s renewable energy goals
