Ukukhishwa Kwamanzi Kuwofondo Olujulile

Ukwenza amawells aphakeme kakhulu ukukhupha amanzi kubalulekile njengendlela yokuthuthukisa umhlaba nokuphathwa kwamanzi esetshenziselwa ukusungulwa kwamaf elelekile nasezinhlelweni ezinkulu zomhlaba. Le ndlela ekhethekile ibandakanya ukukhipha kahle amanzi omhlaba ezindaweni ezingezansi ngezimvunguvungu eziseduzane, kunciphisa i-water table nokubambezela izimo zomhlabathi ngaphambi nangaphakathi kwezokwakha ezinzima. Ukwenza amawells aphakeme kakhulu kuhluke ezinhlelweni zokwakha ezivamile ezingezansi ngenxa yokukwazi kwakho ukubhekana ne-water table ephezulu nezindawo ezikhanyayo ezihamba phansi kakhulu kunokujwayelekile, okwenza kuba kubalulekile emaphrojekthini amakhulu, ukwakhiwa kwama- basement athile, kanye nokufaka izinduku ezinkulu lapho ukuphathwa kwamanzi omhlaba kubalulekile empumelelweni yephrojekthi kanye nokwakhiwa okuqinile. Inqubo yokwenza amawells aphakeme kakhulu isebenzisa amaphethini okuphakela amanzi, avamise ukufakwa ngaphakathi kwemithombo efana no-150 kuya ku-1500 millimitha ububanzi, kuye ngokuqashelwa kwephrojekthi kanye ne-geology engaphansi. Lezi zimpompo zikhupha amanzi omhlaba ngemigqa yokuhlunga nezindawo ze-gravel pack, zidlulisa amanzi ezikhungweni zokwelashwa noma ezindaweni zokuphuma ngenkathi zigcina izilinganiso zokukhipha ezilawulwayo emhlabeni wesikhala sokumba. Izinhlelo zamanje zokwenza amawells aphakeme kakhulu zivame ukufaka izimfanelo zomphakathi noma eziyi-multiplex, zivumela ukusebenza okuqhubekayo kanye ne-capacity yokusekela ngesikhathi sokwakha eside. Ukubhekwa kwe-piezometric kanye nezikhumbi zokubheka izinga lamanzi omhlaba kusemthethweni kumaphrojekthi ukuze kuqinisekiswe ukuthi izinga lokwehlisa liyahlangabezana nezikhwama zokukhipha ezithile nezimiso zemvelo eziphathwe njengomphakathi wokuphatha amanzi namanzi angaphansi. Ukwenza amawells aphakeme kakhulu kwenza imisebenzi eminingi ebalulekile kwezobunjiniyela bemifantu ezinzima nasekufakeni izakhi. Emhlabathini okhubekayo kanye nasemhlabathini okhulayo njengokukhanya, isiphepho, nezinduku ezincane ze-sand, ukukhipha amanzi okuphakeme kakhulu kwephula amandla akhululi, kunciphisa ingcindezi yamathala, futhi kuvinjezele ukujula kwamandla emithonjeni yokumba emakhaya axhume imisebenzi yokushaywa kwezinduku eziyinhloko kanye nezinduku ezinkulu eziboshwe. Emlandweni ejayelekile okubhalwe amalahle nokukhanda, ukukhipha amanzi okuphakeme kakhulu kuvinjezela ukugelezwa kwamanzi, ukuwa, nezinkinga eziphephile ezingathinta ukuhlanganiswa komkhiqizo nezinhlelo zomhlaba eziseduzane. Le ndlela ibalulekile ikakhulukazi ezindaweni zokwakha zasedolobheni, ezinhlelweni zokwakha zolwandle, nasezinhlelweni lapho izakhiwo ezizungezile noma izinsiza zidinga ukufakwa okuncane kwezindawo zomhlaba nezimo ezisemthethweni zamanzi omhlaba. Izicelo zokwenza amawells aphakeme kakhulu zifaka ukwakhiwa kwama-basement amakhulu ezinkampanini nakumakhaya, ukukhanya kwemigudu yokuhamba nendawo yokupaka, imisebenzi ebalulekile yokwakha izisekelo zezimoto nezithuthi, izisekelo zezimoto ezingaphandle nezisensimini, nezinhlelo ezibanzi zokuvuselela ezidinga ukuphathwa kwamanzi omhlaba isikhathi eside. Amaqembu abathengisi abaphatha lezi zinto adinga ukuhambisana okuqondile phakathi kwabezokwakha, osonhlalakahle bezezimali, amaqembu wokushaywa kwezinduku, kanye nezisebenzi ezilungisa ukuhamba kwemvelo ukuze bakwazi ukukhipha izinhlelo ezinzima zokukhipha amanzi eziphumelelisa izigaba zephrojekthi ngenkathi kuvikelwa ukufaneleka kwengaphansi kanye nezakhiwo ezizungezile. Impumelelo yokwenza amawells aphakeme kakhulu ixhomeke ekuxoxiseni okujule, ukuhlonza i-hydrogeological, ukuhlola ama-aquifer, nokwakha kahle izikhala zamawell, imali yokuphakelwa, nezinhlelo zokuhambisa ezikhelwe izimo zomhlaba ezithile nezinjongo zokwakha.
