Some homeowners in South Reno like the utility because it's sustainable. Osgard said, "It's basically a hot water system that goes in a closed loop around the neighborhood so it's totally, totally green."
But others love the price. Most residents pay a flat rate of $85 a month for heating and hot water.
"It has become increasingly costly to operate and maintain the system," an attorney representing Nevada Geothermal said, adding that the system is getting old and needs to be rehabilitated.
Nevada Geothermal is holding a community information session at the South Valleys Library on March 8 at 6 p.m.
