Amanzi ngumthombo wobomi kunye nesiseko sezinto zonke eziphilayo.Ngokukhula kwabemi kunye nophuhliso loqoqosho, imfuno kunye nomgangatho wamanzi uya usiba phezulu kwaye uphezulu.Nangona kunjalo, iqondo longcoliseko liya lisiba nzima kwaye indawo yongcoliseko iya isiba nkulu ngokukhula.Ichaphazela kakhulu impilo yethu, njengesinyithi esinzima, i-pesticides, amanzi angcolileyo avela kwizityalo zemichiza, indlela ephambili yokusombulula ezi ngxaki kukwenza unyango lwamanzi.Injongo yokucoca amanzi kukuphucula umgangatho wamanzi, oko kukuthi, ukususa izinto ezinobungozi emanzini ngokusebenzisa iindlela zobugcisa, kwaye amanzi acociweyo angakwazi ukuhlangabezana neemfuno zamanzi okusela.Le nkqubo ifanelekile kumanzi aphantsi komhlaba kunye namanzi aphantsi komhlaba njengendawo yamanzi akrwada.Amanzi aphathwa ngeteknoloji yokucoca kunye neteknoloji ye-adsorption inokufikelela kwi-GB5479-2006 "uMgangatho woMgangatho waManzi okusela", i-CJ94-2005 "uMgangatho woMgangatho waManzi okuSela" okanye "uMgangatho waManzi okuSela" woMbutho wezeMpilo weHlabathi.Itekhnoloji yokwahlula, kunye neteknoloji yokuvala inzala.Ngomgangatho okhethekileyo wamanzi, njengamanzi olwandle, amanzi olwandle, yila inkqubo yokucoca ngokweyona ngxelo yohlalutyo lomgangatho wamanzi.
