Ngokuphuhliswa okuqhubekayo kokukhuliswa kwezamashishini eTshayina, zonke iintlobo zamanzi amdaka aphezulu ziyanda. Amanzi aphezulu angcolisekileyo aveliswa ngumzi mveliso aya kungcolisa imizimba yamanzi, ukuze izinto ezenzeka kwimizimba yamanzi azinakusinda, zitshabalalisa ibhalansi yendalo; Ukuba amanzi amdaka afune emhlabeni, iya kungcolisa kwakhona amanzi asebusuku, echaphazela ukhuseleko lwamanzi okusela abantu. Ngapha koko, ezinye izinto eziyityhefu kunye nezinobungozi zinokudluliselwa kwikhonkco lokutya kwaye ekugqibeleni zingene emzimbeni womntu, efuna isisongelo sempilo yabantu, efuna unyango oluphezulu lwamanzi amdaka aphezulu.
Okwangoku, amanzi aphambili amdaka aphambili sinokunxibelelana nakubandakanya: Amanzi amdaka eShecCimishey, amayeza amdaka amayeza, ukushicilela kunye namanzi amdaka kunye nokwenza amanzi amdaka. La manzi amdaka anokuqulatha inani elikhulu lezinto eziphilayo, izinto ezinolwazi, izinyithi ezinzima, ezinetyhefu kunye nengozi.
Ubunzima ekuphatheni amanzi amdaka obunqabileyo bukhulu, ikakhulu kubandakanya: okokuqala ,. Uxinzelelo oluphezulu: Ukugxininiswa okuphezulu kwengcoliseko kumanzi amdaka kufuna iindlela zonyango ezinamandla zokususwa ngokufanelekileyo. Okwesibini, ubume obunzima: Amanzi amdaka aphambili ahlala enezinto ezahlukeneyo zokungcoliseka, kwaye ukwakhiwa kwayo kunzima, kwenza ukuba kube nzima ukunyanga. Okwesithathu, ukulinda okungekho mgangathweni: Amanye amanzi amdaka agxilwe kakhulu ayilunganga, kwaye kufuneka anyangwe kwangaphambili nezinye iindlela zonyango. Okwesine, ubuqili obuphezulu: Amanzi aphezulu amdaka anokuqulatha izinto eziyityhefu, ebeka isoyikiso sokhuseleko kwizixhobo zonyango kunye nabaqhubi. Okwesihlanu, ubunzima bezixhobo: Amanzi aphezulu aphambili awotshiweyo kwinkqubo yonyango, ukufezekisa ubunzima bokusebenza kunye nokusetyenziswa kwakhona.
Okwangoku, izixhobo eziphezulu zonyango zifuna ukujongana nolu hlobo lwamanzi amdaka, ubukhulu becala sebenzisa indlela yonyango, indlela ye-chimical indlela yokwahlula-hlula, khetha indlela efanelekileyo yonyango, khetha indlela efanelekileyo yokunyanga.
Ingcali yoKhuseleko lweNkcubeko kwiNdawo yokuSebenza kwi-Showage ngaphezulu kwexesha elingaphezu kweminyaka elishumi, ukuvelisa kunye nophando kunye nokuphuhliswa kwamanzi aphezulu okungcoliseka komhlaba, amandla anokuhlala, anendleko, anendleko, ahlangabezana nemigangatho.
