Get­ting in line with GPCD

The mea­sure­ment GPCD or gal­lons per capita per day is im­por­tant for the City’s Wa­ter Con­ser­va­tion Pro­gram. Wa­ter pur­vey­ors in the state of New Mex­ico are re­quired by the New Mex­ico Of­fice of the State En­gi­neer as a con­di­tion of ap­proval on their wa­ter rights to com­plete the mea­sure­ment an­nu­ally. This in­cludes public util­i­ties, mu­tual wa­ter com­pa­nies, county wa­ter dis­tricts, and mu­nic­i­pal­i­ties. The num­ber is an es­ti­mate of how much wa­ter each per­son uses in one day for var­i­ous pur­poses, such as drink­ing, bathing, cook­ing, and toi­let flush­ing.

For the city’sWater Con­ser­va­tion Pro­gram, the an­nual GPCD is a very im­por­tant data-col­lec­tion ex­er­cise. The data is col­lected from the Buck­man Di­rect Di­ver­sion, the Canyon Road­Water Treat­ment Plant, theWater Divi­sion’s Source and Sup­ply Depart­ment, and theWaste Wa­ter Treat­ment Plant. Wa­ter us­age is also tal­lied for var­i­ous cus­tomer classes through the city’s billing sys­tem. It’s a great op­por­tu­nity for ev­ery­one to share data and to see how all those in­di­vid­ual parts come to­gether to iden­tify our wa­ter sys­tem and our cus­tomers in one big piece. This GPCD num­ber also ties into other pro­gram com­pli­ance re­quire­ment ef­forts and util­ity stud­ies such as the Long-RangeWater Sup­ply Plan, the city’sWater Re­use Fea­si­bil­ity Study, and the Amer­i­canWaterWorks As­so­ci­a­tion (AWWA) wa­ter au­dit.

The City of Santa Fe prides it­self on bring­ing down the GPCD year after year even while the pop­u­la­tion con­tin­ues to grow. With a to­tal sys­tem GPCD of 87 for 2016, Santa Fe has one of the low­est numbers in the en­tire South­west. The GPCD trend helps us look at our pro­gram­ming on an an­nual ba­sis and con­sider if changes need to be made or new pro­grams de­vel­oped. Cal­cu­la­tions on the var­i­ous cus­tomer classes such as res­i­den­tial, multi-fam­ily, and com­mer­cial al­low us to look at op­por­tu­ni­ties within each of those sec­tors as well.

There is some­thing truly grat­i­fy­ing in com­plet­ing the project and in work­ing with oth­ers in var­i­ous de­part­ments to do so. The re­sult lets us know we are all on the right track and that Santa Fe is do­ing a great job con­sid­er­ing our wa­ter sup­ply and changes in the fu­ture. It also gives us use­ful in­for­ma­tion on the suc­cess of wa­ter-con­ser­va­tion ef­forts. For more in­for­ma­tion on the GPCD, please visit­wa­ter­

I’d like to give a per­sonal thank you to TimMichael, who is a mem­ber of our Santa FeWater Con­ser­va­tion com­mit­tee and who spent so much time work­ing with me on the GPCD. His re­view of the data and con­sen­sus at the end of the project was so help­ful and I am truly grate­ful.

Happy Hol­i­days, ev­ery­one!
