Njengesitsha esisetshenziswa kakhulu,izinkomishi zamanzi zensimbi engagqwalibabe nezinzuzo ukuqina, ukuhlanza lula kanye nokuvikelwa kwemvelo. Ukusungulwa kwayo kudlule inqubo ende nejabulisayo. Kulesi sihloko, sizohlola ukusungulwa kwebhodlela lamanzi lensimbi engenasici kanye nezinyathelo zalo ezibalulekile.
Insimbi engagqwali iyingxubevange eyenziwe ngensimbi, i-chromium, i-nickel nezinye izakhi. Kusukela ekuqaleni kwekhulu lama-20, abantu baqala ukutadisha indlela yokusebenzisa insimbi engagqwali ukuze benze iziqukathi ezihlala isikhathi eside. Kodwa-ke, ngaleso sikhathi, ubuchwepheshe bokukhiqiza insimbi engagqwali babungakavuthwa ngokwanele, futhi kwakunzima ukuthola imikhiqizo yekhwalithi ephezulu yensimbi engagqwali.
Ngokuthuthuka kobuchwepheshe bezimboni, ikakhulukazi ngawo-1920 nawo-1930, ubuchwepheshe bokukhiqiza insimbi engagqwali bathuthuka kancane kancane, okwenza kwaba nokwenzeka ukukhiqiza insimbi engagqwali ngezinga elikhulu. Lokhu kwavula indlela yokwakhiwa kwezinkomishi zamanzi zensimbi engagqwali.
Ibhodlela lokuqala lamanzi lensimbi engenasici eliphumelele ngempela laphuma ngawo-1940. Ngalesi sikhathi, insimbi engagqwali yayisivele isetshenziswa kabanzi emikhakheni yezempi neyezindiza, ethandwa ngenxa yokumelana nokugqwala kanye nezindawo zokulwa namagciwane. Abantu baqala ukuqaphela ukuthi amabhodlela amanzi ensimbi engagqwali anokuqina okuhle kakhulu nokuphepha kwezempilo, futhi kancane kancane abangenisa ekuphileni kwansuku zonke.
Nokho, kwakusenezinkinga ezithile ngamabhodlela amanzi ensimbi engagqwali yokuqala. Ngenxa ye-thermal conductivity ephezulu yensimbi engagqwali, kuvame ukuzwakala kushisa kakhulu uma isetshenziswa. Ngaphezu kwalokho, izinkomishi zangaphambili zensimbi engagqwali nazo zazisinda futhi kungelula ukuzithwala. Ukuze kuthuthukiswe lezi zinkinga, abakhiqizi baqala ukucwaninga nokuthuthukisa imiklamo emisha nobuchwepheshe.
Ngokuhamba kwesikhathi, ukwakheka nokusebenza kwamabhodlela amanzi ensimbi engagqwali kuye kwathuthuka kakhulu. Izinkomishi zamanzi zensimbi engagqwali zesimanje ngokuvamile zamukela uhlaka olunezingqimba ezimbili. Isendlalelo se-vacuum phakathi kwezendlalelo zangaphakathi nezingaphandle zingavaleka kahle, zivumele abasebenzisi ukuthi babambe kalula inkomishi ngaphandle kokushisa izandla zabo. Ngesikhathi esifanayo, kunezinketho eziningi kumthamo, ukuma nokubukeka kwezinkomishi zamanzi zensimbi engagqwali ukuhlangabezana nezidingo kanye nokuthandwa komuntu siqu kwabasebenzisi abahlukene.
Emphakathini wanamuhla onokuqwashisa ngezemvelo okwandayo, amabhodlela amanzi ensimbi engagqwali athandwa abantu abaningi ngenxa yezinto zawo ezisebenziseka kabusha, ezihlanzekile futhi ezivumelana nemvelo. Izindawo eziningi ziye zaqala ngisho nohlelo “lokwenqaba ukusebenzisa izinkomishi zepulasitiki ezisetshenziswa kanye” ukuze kukhuthazwe abantu ukuthi basebenzise izinkomishi zamanzi zensimbi engagqwali esimeme.
Ukufingqa, inqubo yokusungulwa kwezinkomishi zamanzi zensimbi engagqwali isidlule eminyakeni eminingi yokuthuthukiswa kwezobuchwepheshe kanye nokusha. Kusukela ocwaningweni lokuqala lwaselabhorethri kuya ekukhiqizweni ngobuningi besimanje, amabhodlela amanzi ensimbi engagqwali enze inqubekelaphambili enkulu mayelana nokuqina, ukuphepha kwezempilo nokuvikelwa kwemvelo. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe kanye nokugcizelela kwabantu kwezempilo kanye nokuvikelwa kwemvelo, amabhodlela amanzi ensimbi engagqwali azoqhubeka nokukhula futhi akhule esikhathini esizayo futhi abe ingxenye ebalulekile yokuphila kwabantu kwansuku zonke.
