"Zopukuta zonyowa tsopano ndi imodzi mwazovuta zazikulu zomwe timakumana nazo potolera makina a Charleston Water Supply System," atero a Baker Mordekai, woyang'anira ntchito yotolera madzi oipa. Zopukuta zakhala vuto mumayendedwe amadzi onyansa kwazaka zambiri, koma vutoli lakula kwambiri pazaka 10 zapitazi ndipo lakula kwambiri ndi mliri wa COVID-19.
Zopukuta zonyowa ndi zida zina zimakhala ndi zovuta zakale. Sasungunuka ngati pepala lachimbudzi, zomwe zimatsogolera ku milandu motsutsana ndi makampani omwe amapanga ndikugulitsa zopukuta zonyowa. Mtundu wotchuka kwambiri ndi Kimberly-Clark. Mitundu yamakampaniyi ndi a Huggies, Cottonelle ndi Scott, omwe adabweretsedwa kukhothi ndi makina operekera madzi ku Charleston, South Carolina. Malinga ndi a Bloomberg News, a Charleston System adagwirizana ndi Kimberly-Clark mu Epulo ndipo adapempha thandizo. Mgwirizanowu ukunena kuti zopukuta zonyowa zamakampani zomwe zidalembedwa kuti "zochapitsidwa" ziyenera kukwaniritsa mulingo wamakampani amadzi akutayidwa pofika Meyi 2022.
Kwa zaka zambiri, vuto lopukutali lawonongera makina operekera madzi ku Charleston mazana masauzande a madola. M'zaka zisanu zapitazi, makinawa adayika ndalama zokwana US $ 120,000 pa zenera lokhala ngati bar la njira yolowera - ndalama zazikulu zokha, osaphatikiza ndalama zoyendetsera ndi kukonza. "Izi zimatithandiza kuchotsa zopukuta zisanayambe kuwononga mtundu uliwonse wa zipangizo zapansi (makamaka zopangira mafakitale)," adatero Mordekai.
Ndalama zazikuluzikuluzi zinali mu supervisory control and data acquisition (SCADA) ya makina opopera 216 a makina, zomwe zimawononga USD 2 miliyoni m'zaka zisanu ndi zitatu. Kukonza zodzitchinjiriza, monga kuyeretsa zitsime zonyowa, kuyeretsa zingwe zazikulu ndi kuyeretsa zotchingira pamalo aliwonse opopera, kumapanganso ndalama zambiri. Ntchito zambiri zidachitika mkati, koma makontrakitala akunja adabweretsedwa kuti azithandizira pafupipafupi, makamaka panthawi ya mliri - $ 110,000 ina idagwiritsidwa ntchito.
Ngakhale Mordekai adanena kuti njira yoperekera madzi ku Charleston yakhala ikulimbana ndi zopukuta kwazaka zambiri, mliriwu wakulitsa vutoli. Mordekai ananena kuti makinawa ankakhala ndi mapampu awiri otsekedwa pamwezi, koma chaka chino pakhala pali mapulagi 8 mwezi uliwonse. Munthawi yomweyi, kuchulukana kwa mzere waukulu kumawonjezekanso kuchokera ku 2 pa mwezi mpaka ka 6 pamwezi.
"Tikuganiza kuti gawo lalikulu la izi ndichifukwa choti anthu akuwonjezera mankhwala ophera tizilombo," adatero. Zikuoneka kuti amatsuka manja awo pafupipafupi. Nsanza zonsezi zikuwunjikana m’kasupe.”
COVID-19 isanachitike, Charleston Water Supply System amawononga US$250,000 pachaka kuti azitha kupukuta zokha, zomwe zidzakwera kufika US$360,000 pofika 2020; Moredekai akuyerekeza kuti idzawononga ndalama zoonjezera za US$250,000 mu 2021, zomwe zikuposa US$500,000.
Tsoka ilo, ngakhale kugawidwanso kwa ntchito, ndalama zowonjezera izi zowongolera zopukuta nthawi zambiri zimaperekedwa kwa makasitomala.
"Kumapeto kwa tsiku, zomwe muli nazo ndikuti makasitomala amagula zopukutira mbali imodzi, ndipo mbali inayo, amawona kuwonjezeka kwa mtengo wa zopukuta zopukuta," adatero Mordekai. "Ndikuganiza kuti nthawi zina ogula amanyalanyaza mtengo."
Ngakhale mliriwu wachepa chilimwe, kutsekeka kwa njira yoperekera madzi ku Charleston sikunachepe. “Mungaganize kuti anthu akabwerera kuntchito, chiŵerengerocho chidzachepa, koma sitinazindikire zimenezi mpaka pano,” anatero Moredekai. “Anthu akakhala ndi chizoloŵezi choipa, zimakhala zovuta kuti asiye chizolowezi chimenechi.”
Kwa zaka zambiri, ogwira ntchito ku Charleston akhala akugwira ntchito zina zophunzitsira kuti ogwiritsa ntchito amvetsetse kuti zopukuta zimatha kuwononganso dongosolo. Chimodzi ndi chochitika cha "Wipes Clog Pipes" chomwe Charleston ndi mabungwe ena am'madera adagwira nawo ntchito, koma Mordekai adanena kuti zochitikazi zangopindula "zopambana zochepa".
Mu 2018, ogwira nawo ntchito adayambitsa kampeni yolimbikitsa anthu kuti alimbikitse ma block ndi zithunzi za anthu osiyanasiyana osatseka ndi manja awo, zomwe zidafalitsidwa padziko lonse lapansi, zomwe zidakhudza anthu opitilira 1 biliyoni. "Tsoka ilo, kuchuluka kwa zopukutira zomwe tidaziwona m'katoni sikunakhudzidwe kwambiri," atero a Mike Saia, woyang'anira zidziwitso pagulu. "Sitinawone kusintha kwa kuchuluka kwa zopukuta zomwe tidatulutsa pazenera komanso njira yoyeretsera madzi oyipa."
Zomwe gulu lachitukuko lachita ndikukopa chidwi pamilandu yoperekedwa ndi makampani ochotsa zimbudzi kudutsa United States ndikupanga dongosolo lamadzi la Charleston kukhala lolunjika kwa aliyense.
"Chifukwa cha kuyesayesa kwa kachilomboka, takhala nkhope yeniyeni ya vuto lakupukuta ku United States. Chifukwa chake, chifukwa chakuwoneka kwathu pantchitoyi, ntchito yayikulu yamalamulo yomwe khothi lonse likuchita idayimitsa ndi kutitenga ngati wodandaula wawo wamkulu, "Saia Say.
Mlanduwo unaperekedwa kwa Kimberly-Clark, Procter & Gamble, CVS, Walgreens, Costco, Target ndi Walmart mu Januwale 2021. Mlanduwu usanachitike, Charleston Water Supply System anali pa zokambirana zapadera ndi Kimberly Clark. Saia adanena kuti akufuna kuthana ndi wopanga, koma sanagwirizane, kotero adasumira mlandu.

Mlanduwu umaphatikizanso kuti opanga azipereka chidziwitso kwa ogula kuti zopukuta zosachapitsidwa sizimachapidwa.
"Zidziwitso ziyenera kutumizidwa pamalo ogulitsa ndikugwiritsidwa ntchito m'sitolo, ndiye kuti, pamapaketi," adatero Saiya. "Izi zimayang'ana kwambiri chenjezo la 'musasambitse' lomwe likutuluka kutsogolo kwa phukusi, pomwe mumachotsa zopukuta m'phukusi."
Milandu yokhudzana ndi zopukutira idakhalapo kwa zaka zambiri, ndipo Saia adati uku ndiye kukhazikitsa koyamba kwa "chinthu chilichonse".
“Timawayamikira chifukwa chopanga zopukutira zenizeni zochapitsidwa ndipo tinavomera kuti aziika zilembo zabwino pa zinthu zomwe sizingachapitsidwe. Ndifenso okondwa kuti apitiliza kukonza zinthu zawo,” adatero Saia.
