Ukuphinda kusetyenziswe amanzi amdaka kuvela njengesisombululo esibalulekileyo kwimingeni yamanzi ehlabathi
Njengoko utshintsho lwemozulu kunye nokunqongophala kwamanzi kuqhubeka nokufaka umngeni kwizixeko nakwimizi-mveliso kwihlabathi liphela, ubuchwepheshe bokunyanga amanzi amdaka kunye nokuhlaziya izinto ezisetyenzisiweyo buba yinxalenye ebalulekileyo yezicwangciso zophuhliso oluzinzileyo.
Kutshanje, amazwe aliqela akhawulezise utyalo-mali kwizisombululo eziphambili zolawulo lwamanzi amdaka, egxile ekusetyenzisweni kwakhona kwamanzi, ekubuyiselweni kwezixhobo, kunye nobuchwepheshe bonyango olusebenzisa ikhabhoni ephantsi. Umzekelo, iGrisi ikhuthaza inkunkumaUkuphinda kusetyenziswe amanzi iiprojekthi e-Athens zokubuyisela amanzi acociweyo ukuze ankcenkceshelwe kunye neendawo eziluhlaza ezidolophini, ukunceda ekunciphiseni uxinzelelo kwimithombo yamanzi acocekileyo.
Ishishini lendalo lehlabathi likwajongene notshintsho oluvela ekulahleni amanzi amdaka ngokwesiko ukuya Uqoqosho olujikelezayo Endaweni yokuphatha amanzi amdaka njengenkunkuma, ubuchwepheshe banamhlanje bujolise ekufumaneni izixhobo ezixabisekileyo ezifana namanzi acocekileyo, amandla, kunye nezondlo.
Ngokweendlela zoshishino, Iinkqubo zokuNyangwa kwamanzi amdaka, ubuchwepheshe be-membrane, ukujonga ngedijithali, kunye nezixhobo ezisebenzisa amandla ngendlela eyongayo ziya kuba ziindlela eziphambili zophuhliso. Ezi zisombululo zivumela uluntu kunye namashishini ukuba aphathe amanzi amdaka kufutshane nendawo aveliswa kuyo, nto leyo ephucula ukusebenza kakuhle kwaye inciphise iindleko zeziseko zophuhliso.
Ukongeza ekunyangweni kwamanzi, oorhulumente bayaqinisa imigaqo-nkqubo yokusingqongileyo kunye notyalo-mali kwiziseko ezingqongileyo. Amazwe aya edibanisa ngakumbi amandla avuselelekayo, ulawulo lwenkunkuma, ukhuseleko lwamanzi, kunye namaqhinga okulungisa imozulu ukuze kufezekiswe ukukhula koqoqosho okuzinzileyo.
Kubavelisi bezixhobo zokusingqongileyo, le ndlela idala amathuba amatsha kwiimarike zehlabathi. Ubuchwepheshe obufana noomatshini bokususa amanzi ngodaka, iinkqubo zonyango lwamanzi amdaka, izixhobo zokucoca, kunye nezixhobo zokubuyisela izixhobo kulindeleke ukuba zidlale indima ebalulekileyo ekuncedeni amashishini ukuba ahlangabezane nemigangatho engqongqo yokusingqongileyo.
Iingcali zikholelwa ukuba ikamva lokukhuselwa kwendalo aliyi kugxila kuphela kulawulo longcoliseko kodwa likwajolise ekudaleni ixabiso kwinkunkuma. Utshintsho oluvela kwishishini "lonyango lwenkunkuma" ukuya kwishishini "lokubuyisela izixhobo" luya kuba ngomnye wemikhwa ebalulekileyo kuqoqosho oluluhlaza lwehlabathi.
