Baker Mordecai, tus thawj saib xyuas kev khaws dej khib nyiab hais tias "Tam sim no ib qho ntawm cov teeb meem loj tshaj plaws uas peb ntsib hauv kev sau cov khoom ntawm Charleston Water Supply System," Cov ntaub so tau muaj teeb meem hauv cov dej khib nyiab rau ntau xyoo lawm, tab sis qhov teeb meem no tau nrawm dua hauv 10 xyoo dhau los thiab tau ua rau muaj kev kis tus kabmob COVID-19.
Cov ntaub so ntub dej thiab lwm yam khoom muaj teeb meem ntev. Lawv tsis yaj zoo li daim ntawv tso quav tso quav, ua rau muaj kev foob rau cov tuam txhab uas tsim thiab muag cov ntaub ntub dej. Lub npe nrov tshaj plaws yog Kimberly-Clark. Lub tuam txhab cov khoom lag luam suav nrog Huggies, Cottonelle thiab Scott, uas tau raug coj mus rau hauv tsev hais plaub los ntawm kev siv dej hauv Charleston, South Carolina. Raws li Bloomberg Xov Xwm, Charleston System tau mus txog kev sib hais haum nrog Kimberly-Clark thaum lub Plaub Hlis thiab tau thov kev pab cuam. Daim ntawv cog lus tau teev tseg tias lub tuam txhab cov ntaub so ntub dej uas cim tias "ntxuav" yuav tsum ua kom tau raws li kev lag luam dej khib nyiab los ntawm lub Tsib Hlis 2022.
Tau ntau xyoo, qhov teeb meem so no tau ua rau Charleston cov khoom siv dej ntau pua txhiab daus las. Hauv tsib xyoos dhau los, lub kaw lus tau nqis peev US $ 120,000 ntawm qhov screen-zoo li lub vijtsam ntawm kev nkag-tsuas yog cov nqi peev, tsis suav nrog cov nqi khiav haujlwm thiab kev saib xyuas. "Qhov no pab peb tshem tawm cov ntaub so ua ntej lawv ua rau txhua yam kev puas tsuaj rau cov khoom siv qis qis (tsuas yog cov nroj tsuag ua haujlwm)," Mordecai hais.
Qhov kev nqis peev loj tshaj plaws yog nyob rau hauv kev tswj xyuas kev tswj hwm thiab kev nrhiav tau cov ntaub ntawv (SCADA) ntawm qhov system 216 qhov chaw nres tsheb, uas raug nqi $ 2 lab hauv yim xyoo. Kev tiv thaiv kev saib xyuas, xws li kev tu dej ntub dej, kev tu lub hauv paus thiab kev tshuaj ntsuam xyuas ntawm txhua qhov chaw tso dej, kuj yog ib qho kev nqis peev loj. Feem ntau ntawm cov haujlwm tau ua tiav sab hauv, tab sis cov neeg cog lus sab nraud tau raug coj los pab cuam tshuam, tshwj xeeb tshaj yog thaum muaj kev sib kis - lwm qhov $ 110,000 tau siv.
Txawm hais tias Mordecai tau hais tias Charleston cov khoom siv dej tau cuam tshuam nrog cov ntaub so rau ntau xyoo lawm, kev sib kis tau ua rau muaj teeb meem loj dua. Mordecai tau hais tias lub kaw lus tau siv ob lub twj tso kua mis ib hlis, tab sis xyoo no muaj 8 lub tshuab txuas ntxiv rau ib hlis. Nyob rau tib lub sij hawm, txoj kab tseem ceeb congestion kuj tau nce los ntawm 2 zaug hauv ib hlis mus rau 6 zaug hauv ib hlis.
"Peb xav tias feem ntau ntawm qhov no yog vim tib neeg ua tshuaj tua kab mob ntxiv," nws hais. “Lawv pom tseeb tias lawv ntxuav tes ntau zaus. Tag nrho cov rags no tau sau rau hauv cov kav dej phwj tuaj. "
Ua ntej COVID-19, Charleston Water Supply System raug nqi US $ 250,000 toj xyoo los tswj cov ntaub so ib leeg, uas yuav nce mus txog US $ 360,000 los ntawm 2020; Mordecai kwv yees tias nws yuav siv nyiaj ntxiv US $ 250,000 hauv 2021, tag nrho ntau dua US $ 500,000.
Hmoov tsis zoo, txawm tias qhov chaw ua haujlwm, cov nqi ntxiv ntawm kev tswj cov ntaub so no feem ntau dhau mus rau cov neeg siv khoom.
Mordechai tau hais tias "Thaum hnub kawg, qhov koj muaj yog cov neeg siv khoom yuav cov ntaub so ntawm ib sab, thiab ntawm qhov tod tes, lawv pom kev nce nqi ntawm cov kav dej ntawm cov ntaub so," Mordechai hais. "Kuv xav tias cov neeg siv khoom qee zaum saib tsis taus tus nqi."
Txawm hais tias tus kab mob kis thoob qhov txhia chaw tau yooj yim rau lub caij ntuj sov no, qhov thaiv ntawm Charleston txoj kev siv dej tsis tau txo qis. Mordecai hais tias "Koj yuav xav tias thaum tib neeg rov qab mus ua haujlwm, tus lej yuav txo qis, tab sis peb tsis tau pom qhov no txog tam sim no," Mordecai hais. "Thaum tib neeg tsim tus cwj pwm phem, nws nyuaj rau tshem tawm tus cwj pwm no."
Ntau xyoo dhau los, cov neeg ua haujlwm hauv Charleston tau ua qee yam kev kawm los ua kom cov neeg siv hluav taws xob nkag siab tias cov ntaub so dej tuaj yeem ua rau lub cev tsis zoo ntxiv. Ib qho yog "Wipes Clog Pipes" qhov xwm txheej uas Charleston thiab lwm lub chaw siv hluav taws xob hauv cheeb tsam tau koom nrog, tab sis Mordecai hais tias cov xwm txheej no tsuas yog ua tiav "kev vam meej tsawg".
Hauv xyoo 2018, cov neeg ua haujlwm tau tshaj tawm kev tshaj tawm xov xwm los txhawb cov clogs thiab cov duab ntawm cov neeg tawm tsam tsis cuam tshuam nrog lawv txhais tes, uas tau nthuav tawm thoob plaws ntiaj teb, cuam tshuam ntau dua 1 billion tus neeg. "Hmoov tsis zoo, tus naj npawb ntawm cov ntaub so peb tau pom hauv cov txheej txheem sau tseg tsis muaj kev cuam tshuam loj," Mike Saia, tus thawj coj saib xyuas pej xeem cov ntaub ntawv tau hais. "Peb tsis pom muaj kev hloov pauv ntawm cov ntaub so peb tau tawm ntawm lub vijtsam thiab los ntawm cov txheej txheem kho dej khib nyiab."
Qhov kev txav mus los hauv zej zog tau ua li cas yog txhawm rau mloog cov lus foob foob los ntawm cov tuam txhab kho dej phwj tuaj thoob plaws Tebchaws Meskas thiab ua rau Charleston dej system ua kom pom tseeb ntawm txhua tus neeg.
"Vim qhov kev mob siab rau tus kab mob no, peb tau dhau los ua lub ntsej muag tiag tiag ntawm cov teeb meem so hauv Tebchaws Meskas. Yog li ntawd, vim peb pom kev hauv kev lag luam, txoj haujlwm tseem ceeb hauv kev cai lij choj uas tag nrho lub tsev hais plaub tau ua tau raug ncua thiab tau txais peb los ua lawv tus neeg foob, "Sia Say.
Kev foob raug foob Kimberly-Clark, Procter & Gamble, CVS, Walgreens, Costco, Target thiab Walmart thaum Lub Ib Hlis 2021. Ua ntej kev foob, Charleston Water Supply System tau sib tham nrog Kimberly Clark. Saia tau hais tias lawv xav daws nrog cov neeg tsim khoom, tab sis tsis tuaj yeem ncav cuag qhov kev pom zoo, yog li lawv tau foob.
Thaum cov kev foob no raug foob, cov neeg ua haujlwm ntawm Charleston Water Supply System xav kom cov ntaub so ntswg uas sau tias "flushable" tiag tiag flushable, thiab lawv yuav "kis" nyob rau hauv lub sij hawm thiab nyob rau hauv ib txoj kev uas yuav tsis ua clogging los yog ntxiv. cov teeb meem kev saib xyuas. . Qhov kev foob tseem suav nrog kev xav kom cov tuam txhab tsim khoom muab cov neeg siv khoom paub zoo dua tias cov ntaub so tsis ntxuav tsis tuaj yeem ntxuav.
"Cov ntawv ceeb toom yuav tsum raug xa tawm ntawm qhov muag thiab siv hauv khw, uas yog, ntawm lub ntim," Saiya hais. "Qhov no tsom mus rau 'tsis txhob yaug' cov lus ceeb toom tawm ntawm lub hauv ntej ntawm lub pob, qhov zoo yog qhov uas koj nqa cov ntaub so tawm ntawm lub pob."
Kev foob hais txog cov ntaub so tau muaj rau ntau xyoo, thiab Saia tau hais tias qhov no yog thawj qhov kev sib hais haum ntawm "txhua yam khoom".
"Peb qhuas lawv rau kev tsim cov ntaub so ntswg tiag tiag thiab pom zoo muab cov ntawv sau zoo dua rau lawv cov khoom tsis ntxuav. Peb kuj zoo siab tias lawv yuav txuas ntxiv txhim kho lawv cov khoom, "Sia hais.
