Micro-hydro spooling up: Logan city project will power 185 homes

Logan Light & Power hopes to kill multiple birds with one stone when its new hydroelectric generator goes online in the near future. The facility, installed last week on the culinary water pipeline at the mouth of Logan Canyon, will provide enough electricity to power nearly 200 homes while emitting no carbon into the atmosphere.

Two years ago, Logan city built a new drinking water line to replace the decaying older pipeline. With the new pipe, however, came new complications in the form of excess pressure. For the past two years, the city has used a pressure reducing valve to address the excess build-up. It works, but it creates new problems of its own. Enter the new hydroelectric generator, which will not only bleed excess pressure from the pipeline, but will also convert it into usable, sustainable, eco-friendly electricity. Logan Herald Journal
