Okwangoku, eli shishini linolwazi oluhle ngolawulo lokusingqongileyo ezidolophini. Ihlabathi kunye neTshayina zinamava aneleyo kunye neemodeli zokubhekisela. Inkqubo yamanzi yezixeko eTshayina ibandakanya imithombo yamanzi, ukufunxwa kwamanzi, ukutsalwa kwamanzi, iinkqubo zolawulo, imithombo yamanzi yendalo, kunye nokukhuselwa kokusingqongileyo kwamanzi ezidolophini. Kukwakho neengcinga ezicacileyo. Kodwa emaphandleni, imeko itshintshe ngokupheleleyo. Umzekelo, malunga nemithombo yamanzi, kukho iindlela ezininzi zokufumana amanzi kunasezidolophini. Abantu banokusebenzisa ngokuthe ngqo imithombo yamanzi ejikelezileyo, amanzi angaphantsi komhlaba okanye amanzi avela kuthungelwano lwemilambo njengemithombo yamanzi okusela; malunga nokutsalwa kwamanzi, iindawo zasemaphandleni azifani nezixeko ezinemigangatho engqongqo yonyango lwamanzi amdaka. Uthungelwano lwezityalo kunye nemibhobho. Ngoko ke inkqubo yokusingqongileyo kwamanzi ezilalini ibonakala ilula, kodwa ineengxaki ezingapheliyo.

Ukutyala, ukuzala kunye nokulahla inkunkuma zizinto ezibalulekileyo ezibangela ungcoliseko lwamanzi emaphandleni.

Umthombo wamanzi okusela welali unokungcoliswa yintsimi yasefama, imfuyo kunye nokufuywa kweenkukhu, ukungena kwenkunkuma okanye kwindlu yangasese, kwaye indawo yamanzi yasemaphandleni inokungcoliswa yinkunkuma yasekhaya yasemaphandleni, izichumisi kunye nezibulali-zinambuzane ezivela kwimithombo yezolimo engeyiyo indawo, kunye nee-antibiotics ezivela kwimfuyo kunye nokufuywa kweenkukhu. . Ke ngoko, imiba yokusingqongileyo yasemaphandleni ayipheleli kwiindawo zasemaphandleni kuphela, kodwa ikwanxulumene nomntu wonke kunye nolawulo lokusingqongileyo kwamanzi kwisitya somlambo.

Akwanelanga ukuqwalasela amanzi kuphela kwindawo yamanzi asemaphandleni. Inkunkuma kunye nococeko nazo zizinto ezibalulekileyo ezichaphazela indawo yamanzi. Ulawulo lwendawo yamanzi asemaphandleni yiprojekthi ebanzi necwangcisiweyo. Xa sithetha ngamanzi, akukho ndlela yokuphuma. Kufuneka siqwalasele ukuphelela kwawo. Nokusebenza kwawo. Umzekelo, amanzi amdaka kunye nenkunkuma kufuneka ziphathwe ngaxeshanye; ukufuywa kwemfuyo kunye neenkukhu kunye nongcoliseko lwezolimo olungeyondawo kufuneka lulawulwe ngokupheleleyo; imithombo yamanzi kunye nomgangatho wobonelelo lwamanzi kufuneka kuphuculwe ngokusebenzisana; imigangatho kunye nolawulo kufuneka zilungelelaniswe neemeko zasekuhlaleni.

Ngoko ke, kwixesha elizayo, akufuneki sigxile kuphela kunyango nasekulahlweni, kodwa kufuneka sigxile nakulawulo longcoliseko kunye nokusetyenziswa kwezixhobo. Kufuneka siqwalasele imeko-bume yamanzi yasemaphandleni ngokwembono yolawulo olupheleleyo, kubandakanya inkunkuma, ucoceko, ukufuywa kwemfuyo kunye neenkukhu, ezolimo, kunye nemithombo engeyondawo. Linda, le yindlela ebanzi yokucinga ngokulawula imeko-bume yamanzi yasemaphandleni. Amanzi, umhlaba, igesi, kunye nenkunkuma eqinileyo kufuneka ziphathwe kunye, kwaye ukukhutshwa, ukulahla okuphakathi, ukuguqulwa, kunye nemithombo eyahlukeneyo ebandakanyekayo kufuneka ilawulwe kumjikelo weenkqubo ezininzi kunye nemithombo emininzi. Okokugqibela, kubalulekile ukuba amanyathelo amaninzi afana netekhnoloji, ubunjineli, umgaqo-nkqubo, kunye nolawulo asebenze.
