Ngophuhliso lweshishini lezonyango kunye nokwaluphala kwabantu, amaziko ezonyango avelisa amanzi amdaka amaninzi nangakumbi. Ukuze kukhuselwe okusingqongileyo kunye nempilo yabantu, urhulumente ukhuphe uthotho lwemigaqo-nkqubo kunye nemigaqo, efuna amaziko ezonyango ukuba afake kwaye asebenzise izixhobo zonyango lwamanzi amdaka, unyango olungqongqo kunye nokubulala iintsholongwane emanzini amdaka, ukuqinisekisa ukuba ukukhutshwa kwawo kuyahlangabezana nemigangatho.
Amanzi amdaka ezonyango aqulathe inani elikhulu leentsholongwane ezibangela izifo, iintsalela zamayeza kunye nongcoliseko lweekhemikhali. Ukuba akhutshwa ngqo ngaphandle konyango, aya kubangela umonakalo omkhulu kwindalo esingqongileyo nakwimpilo yabantu.
Ukuze kuthintelwe ubungozi bamanzi amdaka ezonyango kwindalo esingqongileyo nakwimpilo yabantu, kugxininiswa imfuneko yezixhobo zonyango lwamanzi amdaka ezonyango. Izixhobo zonyango lwamanzi amdaka ezonyango zinokususa ngokufanelekileyo izinto eziyingozi emanzini amdaka ezonyango kwaye zihlangabezane nemigangatho yokukhupha echazwe lilizwe. Ezi zixhobo zihlala zisebenzisa iindlela zonyango zomzimba, iikhemikhali kunye nebhayoloji, ezinje ngemvula, ukuhluza, ukubulala iintsholongwane, unyango lwe-biochemical, ukususa izinto ezixhonyiweyo, izinto eziphilayo, iintsholongwane ezibangela izifo, izinto ezine-radioactive, njl.njl. emanzini amdaka.
Ngamafutshane, imfuneko yezixhobo zonyango lwamanzi amdaka ayinakutyeshelwa. Amaziko ezonyango kufuneka abeke ukubaluleka okukhulu ekuphathweni kwamanzi amdaka ezonyango, afake kwaye asebenzise izixhobo zonyango ezifanelekileyo, kwaye aqinisekise ukuba amanzi amdaka ezonyango akhutshwa kumgangatho ofanelekileyo. Ukufakwa nokusetyenziswa kwezixhobo zonyango lwamanzi amdaka ezonyango luxanduva olusemthethweni nolwentlalo lwamaziko ezonyango. Kwangaxeshanye, urhulumente noluntu kufuneka baqinise ukubekwa esweni nasekupapashweni konyango lwamanzi amdaka ezonyango, kwaye baphucule ulwazi loluntu ngokhuseleko lokusingqongileyo, olukwayindlela ebalulekileyo yokukhusela impilo yabantu kunye nokhuseleko lokusingqongileyo.
Iimveliso zochungechunge lwe-blue whale ezikhusela indalo zisebenzisa ukubulala iintsholongwane kwi-UV, ukungena ngamandla, zinokubulala i-99.9% yeebhaktheriya, ziqinisekise ngcono unyango lwamanzi amdaka aveliswa zizikhungo zonyango, kunye nonyango lwempilo.
