“Iizinto zokusula ezimanzi ngoku ngomnye weyona miceli mngeni inkulu esijongene nayo kwinkqubo yokuqokelela i-Charleston Water Supply System,” utshilo u-Baker Mordecai, umphathi woqokelelo lwamanzi amdaka. Ukusula bekuyingxaki kwinkqubo yamanzi amdaka amashumi eminyaka, kodwa le ngxaki iye yanda kule minyaka ili-10 idlulileyo kwaye iye yaqatsela ngobhubhani we-COVID-19.
Ukosula okumanzi kunye nezinye izinto zineengxaki ezihlala ixesha elide. Azinyibiliki njengephepha lendlu yangasese, nto leyo ekhokelela kwizimangalo ezichasene neenkampani ezenza kwaye zithengise izinto zosula ezimanzi. Olona phawu ludumileyo nguKimberly-Clark. Iimpawu zale nkampani ziquka ii-Huggies, i-Cottonelle kunye ne-Scott, eziziswe enkundleni yinkqubo yokubonelela ngamanzi e-Charleston, eMzantsi Carolina. Ngokutsho kweBloomberg News, iCharleston System yafikelela kwisigqibo kunye noKimberly-Clark ngo-Epreli kwaye yacela isiqabu. Isivumelwano simisela ukuba izinto zokusula ezimanzi zenkampani eziphawulwe “njengezinokuhlanjwa” kufuneka zihlangabezane nomgangatho woshishino lwamanzi amdaka ngoMeyi wama-2022.
Ukutyhubela iminyaka, le ngxaki yosula ibize inkqubo yonikezelo lwamanzi yaseCharleston amakhulu amawaka eedola. Kwiminyaka emihlanu edlulileyo, inkqubo ityale i-US $ 120,000 kwi-bar-shaped screen ye-entry channel-kuphela iindleko zemali, zingabandakanyi iindleko zokusebenza kunye nokugcinwa. "Oku kusinceda ukuba sisuse izinto zokucima ngaphambi kokuba zenze naluphi na uhlobo lomonakalo kuzo naziphi na izixhobo ezisezantsi (ingakumbi izityalo ezilungisayo)," watsho uMordekayi.
Olona tyalo-mali lukhulu kulawulo lokusuphavayiza kunye nokufunyanwa kwedatha (SCADA) yezikhululo zokumpompa zenkqubo ezingama-216, ezixabisa i-USD 2 yezigidi kwiminyaka esibhozo. Ulondolozo lothintelo, olufana nokucocwa kwequla elimanzi, ukucocwa kwemigca engundoqo kunye nokucocwa kwesikrini kwisikhululo sokumpompa ngasinye, nako kwenza utyalo-mali olukhulu. Uninzi lomsebenzi wenziwa ngaphakathi, kodwa iikontraka zangaphandle zaziswa ukuba zincede ngamaxesha athile, ngakumbi ngexesha lobhubhani-kwachithwa enye i-110,000 yeedola.
Nangona uMordekayi wathi inkqubo yonikezelo lwamanzi yaseCharleston ibijongene nokosula amashumi eminyaka, ubhubhane uye wayenza mandundu ingxaki. UMordekayi uthe inkqubo ibidla ngokuvaleka iipompo ezimbini ngenyanga, kodwa kulo nyaka bekukho iiplagi ezisi-8 ngaphezulu ngenyanga. Ngexesha elifanayo, ukuxinana komgca oyintloko kunyuke kwakhona ukusuka kwi-2 ngenyanga ukuya kwii-6 ngenyanga.
“Sicinga ukuba uninzi lwale nto kungenxa yokuba abantu benza okongezelelekileyo ngokubulala iintsholongwane,” utshilo. “Kuyabonakala ukuba bazicoca rhoqo izandla zabo. Onke la madlavu aqokelelana kumbhobho wogutyulo.”
Phambi kwe-COVID-19, i-Charleston Water Supply System ixabisa i-US$250,000 ngonyaka ukulawula izinto zokucima iyodwa, eyakuthi inyuke iye kuma-US$360,000 ngo-2020; UMordekayi uqikelela ukuba iza kuchitha i-US$250,000 eyongezelelweyo ngo-2021, iyonke ngaphezu kwe-US $500,000.
Ngelishwa, ngaphandle kokwabiwa kwakhona komsebenzi, ezi ndleko zongezelelweyo zokulawula izinto zokucima zidla ngokugqithiselwa kubathengi.
“Ekupheleni kosuku, into onayo kukuba abathengi bathenga izinto zosula kwelinye icala, kwaye kwelinye icala, babona ukonyuka kweendleko zemijelo yokusula,” utshilo uMordekayi. "Ndicinga ukuba abathengi ngamanye amaxesha bayayihoya indleko."
Nangona ubhubhane wehlile kweli hlotyeni, ukuvaleka kwenkqubo yonikezelo lwamanzi kaCharleston akukhange kwehle. Ucinga ukuba xa abantu bebuyela emsebenzini, inani labo liza kuncipha, kodwa asikaqapheli oku okwangoku, utshilo uMordekayi. Xa abantu sele benomkhwa ombi, kuba nzima ukwahlukana nalo mkhwa.”
Ukutyhubela iminyaka, abasebenzi baseCharleston baye benza imisebenzi yokufundisa ukuvumela abasebenzisi bezinto eziluncedo ukuba baqonde ukuba ukugungxulwa kosuleli kunokubangela ukuthotywa kwenkqubo ngakumbi. Omnye ngumsitho othi "Sula imibhobho yeClog" uCharleston kunye nezinye izinto eziluncedo zengingqi ezithathe inxaxheba, kodwa uMordekayi uthe ezi ziganeko zizuze kuphela "impumelelo encinci".
Ngo-2018, abasebenzi baphehlelele iphulo leendaba zosasazo zokukhuthaza iiclogs kunye neefoto zeentlobo ezahlukeneyo zokuvala iiclogs ngezandla zabo, ezasasazwa kwihlabathi liphela, zichaphazela abantu abangaphezu kwebhiliyoni enye. Ngelishwa, inani lokusula esilibonileyo kwinkqubo yokuqokelela alichaphazelekanga kakhulu, utshilo uMike Saia, umlawuli wolwazi loluntu. “Asibonanga tshintsho kwinani lezinto zosula esizikhuphileyo kwiscreen nakwinkqubo yokucocwa kwamanzi amdaka.”
Into eyenziwa ngumbutho wezentlalo kukutsalela ingqalelo kumatyala afakwe ziinkampani zokucoca ugutyulo kulo lonke elase-United States kwaye yenze inkqubo yamanzi yaseCharleston ibe yeyona nto iphambili kwingqalelo yomntu wonke.
“Ngenxa yolu mzamo wentsholongwane, siye saba ngowona buso bengxaki yokusula e-United States. Ke ngoko, ngenxa yokubonakala kwethu kolu shishino, owona msebenzi uphambili wezomthetho owenziwa yinkundla yonke usimisile kwaye samkele njengommangali wabo ophambili, ”utshilo uSaia.
Isimangalo safakwa kwi-Kimberly-Clark, i-Procter & Gamble, i-CVS, i-Walgreens, i-Costco, i-Target kunye ne-Walmart ngoJanuwari 2021. Ngaphambi kwesimangalo, i-Charleston Water Supply System yayithethathethwano lwangasese kunye noKimberly Clark. USaia uthe bafuna ukuzinza nomenzi, kodwa abakwazanga ukufikelela kwisivumelwano, bafaka isimangalo.
Xa ezi zimangalo zifakiweyo, abasebenzi beNkqubo yokuBonelela ngaManzi yaseCharleston babefuna ukuqinisekisa ukuba ezosula ezibhalwe “ezigungxulwayo” zazinokugungxulwa ngokwenene, kwaye “ziya kusasazeka” ekuhambeni kwexesha nangendlela engayi kubangela ukuvaleka okanye ukongezelela. imiba yogcino. . Isimangalo sikwabandakanya ukufuna abavelisi ukuba babonelele abathengi ngesaziso esingcono sokuba izinto zosula ezingahlanjwayo azihlambeki.
"Izaziso kufuneka zithunyelwe kwindawo yokuthengisa kunye nokusetyenziswa evenkileni, oko kukuthi, kwipakethe," utshilo uSaiya. "Oku kugxile kwisilumkiso 'sokungahlambuluki' esiphuma ngaphambili kwiphakheji, kanye apho ususa khona izinto zokucima kwiphakheji."
Izimangalo eziphathelele kwezosula zikhona iminyaka emininzi, kwaye uSaia wathi esi sisisombululo sokuqala sayo nayiphi na into.
“Siyabancoma ngokwenza izinto zokwesulwa zokwenyani ezihlambekayo kwaye bavumile ukubeka iilebhile ezingcono kwiimveliso zabo ezingahlanjwayo. Sikwayavuya kukuba bazakuqhuba bephucula iimveliso zabo,” utshilo uSaia.
