The San Bernardino Municipal Water Department's Geothermal Heating District serves the City of San Bernardino with a low-cost ecologically-correct alternative to fossil fuel heating.  The Geothermal Heating District operates 365 days a year and was formed in 1984.  District heating rates were established to be at 75 percent the cost of gas or less.  Direct geothermal use inlet costs are at half the regular water rates which equates out to 44 cents per hundred cubic foot or 748 gallons of fluid.  This very soft water or fluid, as we call it, is less than one grain hardness and ideal for laundry-type application.  Eighteen miles of insulated distribution lines transport this fluid throughout the downtown hub and surrounding areas.  Twin 200 horse turbines provide power for pumping capacity, which is capable of producing approximately 4,200 gallons per minute.  If you should have any questions on availability or system start-up, please feel free to contact San Bernardino Water Department for further details.
