Iyini imvelo yamanzi? Imvelo yamanzi isho umthelela wemithombo yamanzi emifuleni, emachibini, ezilwandle, emiseleni nasemiseleni ezintweni eziphilayo endaweni. Amanzi awawona nje umsuka wokuphila, kodwa futhi ayingxenye ebalulekile yezilwane nezitshalo. Ngakho-ke, ukubaluleka kwemvelo yamanzi kuyabonakala.

Namuhla, ngokuthuthuka okusheshayo kokwakhiwa kwedolobha lezimboni zesimanje, zonke izinhlobo zokuthuthwa kwendle ziholela ngokungathi sína ekushintsheni kwezinga lamanzi emfuleni, emfuleni, echibini nasolwandle, ikakhulukazi okuhlanganisa ukungcoliswa kwamanzi amakhemikhali ezimbonini, ukungcoliswa kwezibulala-zinambuzane nomanyolo kanye nokungcoliswa kwendle, nokubamba iqhaza kwamakhemikhali ayingozi kuholela ekwehleni noma ekulahlekeni kwenani lokusetshenziswa kwamanzi, okuholela ekwehleni kokusetshenziswa kwamanzi kancane kancane. Ngakho indlela yokuthuthukisa imvelo yamanzi?

Okokuqala nje, kufanele sinqamule ukungcola futhi sikunqande. Kufanele simise ukuchithwa kwendle emthonjeni wokungcola, sivikele nezinsiza zemifula, amachibi namanzi olwandle.

Okwesibili, kufanele siqinise ukuhlanzwa kokuthuthwa kwendle emadolobheni, siqinise ngokuqinile umthetho ezinkampanini zezimboni ezeqa izinga noma ezenqatshelwe ukukhipha, futhi siwavale ngokuqondile lawo angathi sína.

Bese-ke, ukuze kuqiniswe ukuqwashisa ngokuvikelwa kwemvelo kuzo zonke izakhamuzi, ukuvikelwa kwemithombo yamanzi kudinga zonke izakhamuzi ukuba zibambe iqhaza ekulungisweni.

Khona-ke, ukwakhiwa kwesistimu yokuhlanza imithombo yamanzi yemvelo, kusukela empandeni ukuxazulula inkinga yekhwalithi yamanzi, nokuqinisekisa ukuthi ihlala isikhathi eside futhi isebenza ngempumelelo.

Ukuze wenze abantu baphuze amanzi ahlanzekile, i-Honcha isungule ngempumelelo futhi yathuthukisa imishini yomshini wezitini zesikwele, ethwala iminyaka engaphezu kwengu-20 yesipiliyoni sembonini, futhi ngokushesha ithatha imakethe enezici zokusetshenziswa kwamandla okuphansi, ukukhishwa kwe-zero nokuvikelwa kwemvelo okuphezulu. Okubalulekile ukuthi imikhiqizo yesikwele yemishini yezitini inezinhlobonhlobo zokuzivumelanisa nezimo, ezingasetshenziswa ekulawuleni umfula kanye nechibi, ukwakhiwa kokugcinwa kwamanzi, ukwakhiwa kokuvikela umthambeka, ukwakhiwa kohlelo lwamanzi asemadolobheni, njll. Ngaphezu kwalokho, imikhiqizo yemishini yezitini yesikwele inekhono elihle lokuhlanzwa kwemithombo yamanzi. Njengamanje, imishini yomshini wezitini zesikwele isiyinto ebaluleke kakhulu yokwakha imvelo ukuze kwakhiwe ukuvikelwa kwemvelo yamanzi eChina.
