July 20, 2018 – Overall, NID’s treated water customers consumed 20 percent less water in May than in 2013, the benchmark year used before the drought.

In terms of daily water use, NID customers averaged 160 residential gallons per capita day (R-GPCD) in May. Statewide, the average was 94.4 R-GPCD for the same period.

Also, a comparison of May usage through the years indicates we are being less diligent. Estimated R-GPCD for NID treated water customers during the month of May (2013 – 2018):

May 2013-199                                                                                                                                       May 2015-72

May 2016-72

May 2017-154

May 2018-160

NID customers used 160 R-GPCD during May. By comparison, here is a sampling of neighboring district R-GPCDs:

  • Placer County Water Agency – 152
  • El Dorado Irrigation District – 183
  • Sacramento Suburban Water District – 120
  • City of Roseville – 109
  • City of Lincoln – 121

Since 2015, NID has joined other urban water agencies in California in submitting monthly data to the State Water Resources Control Board, which uses the data for its statewide conservation updates. Read the May report here.
