In partnership with the Mojave Water Agency the district is conducting an evaporation cooler water usage study in the Joshua Tree, Johnson Valley, Apple Valley and surrounding areas.  The data from this study will be for calculating consumptive use water regulations in the near future. When the meters are placed on the cooler lines a series of questions will be recorded including, location, weather data, type of cooler and model number. The team will be working with UC Davis, to peer review the data.  UC Davis is completing water bill collections and correlating that information with energy use through Edison bills.  Community homeowner volunteers will allow a water meter to be placed on the water line to their swamp coolers.  An initial reading will be noted, and further periodic readings taken for water consumption data.  This data will then go to Mojave Water Agency for analysis.
