Eminyakeni eyishumi ezayo, ubuchwepheshe benzwa yamanzi buzoba yinto emisha elandelayo enkulu.Kulinganiselwa ukuthi ngo-2030, izinga lale mboni lizodlula ama-dollar ayizigidi eziyizinkulungwane ezimbili, okuyithuba elibanzi labantu abaningi kanye nemakethe enomthelela emhlabeni jikelele.Ukuze udale uhlelo olusebenza kahle noluthuthukisiwe, inethiwekhi yokuphakelwa kwamanzi kanye namanzi angcolile kufanele iphendule ngokushesha nangokunembile imibuzo eminingi-ingabe amanzi asekhaya aphephile?Indlela yokubikezela ngokunembile nokubala ukusetshenziswa kwamanzi kwekhasimende?Ingabe indle ilashwe kahle?Le mibuzo ingaphendulwa ngokuphumelelayo ngezinzwa: dala inethiwekhi yokuphakelwa kwamanzi ehlakaniphile kanye nenethiwekhi yokuhlanza indle.
I-Sinomeasure inezixazululo eziningi ezahlukene ezinganikezwa izinsiza zamanzi kanye nezindawo zikamasipala ukwenza amanethiwekhi azo abe yidijithali.Lezi zinzwa zihlukaniswe izindawo ezinhlanu eziyinhloko:
· Isilinganiso somfutho wepayipi
· Isilinganiso sokugeleza
· Ukuqapha izinga
· Izinga lokushisa
· Ukuhlaziywa kwezinga lamanzi
Lezi zinzwa zingasetshenziswa ezinhlobonhlobo zezicelo ezimbonini zamanzi namanzi angcolile ukusiza izinkampani kanye nomasipala ukufeza izinhloso zabo.Angasetshenziswa kumanethiwekhi amapayipi okuhambisa amanzi, izindawo zokuhlanza amanzi, amanethiwekhi amapayipi amanzi angcolile kanye nezindawo zokuhlanza amanzi angcolile.Siza ukuthuthukisa ukusebenza kahle komsebenzi futhi uthuthukise ukunemba kokuqapha.
