Amanzi Okuphuza
Amanzi awumthombo wokuphila kanye nezinto ezidingekayo ukuze kusetshenziswe umzimba womuntu.Ukuze kuqinisekiswe ukuphepha kwamanzi ayisisekelo, i-China yakha futhi yamemezela izinga lokuhlanzeka kwamanzi okuphuza (GB5749-2006) ekuqaleni kuka-2007. Eqinisweni, lapho abantu bethatha isinyathelo sokuqala sokusebenzisa amanzi, kunzima ukuzuza ngempela impilo enempilo futhi izinga eliphezulu lamanzi.Ukuze kuvikelwe impilo futhi kuqinisekiswe izinga lokuphila, ukuhlunga izici ezihlukahlukene (ezingokomzimba, zamakhemikhali nezezinto eziphilayo) ezithinta impilo emanzini okuphuza kuye kwaba yisidingo esivamile sezakhamuzi.
Ukwelapha Amanzi Ezentengiso
Ukunikezwa kwamanzi okuphuza endaweni eyodwa endaweni yomphakathi (izikole, izibhedlela, iziteshi, izindawo zokudlela, inxanxathela yezitolo, ukuphathwa kwemigwaqo, njll.) kuwukubonakaliswa kwenqubekelaphambili yomphakathi futhi kusiza ukuthuthukisa ukuthandwa kwabathengi.Ikakhulukazi ku-pneumonia ye-coronavirus yenoveli, ukunikezwa okunganele kwezinto zokwakha kuya ngokuya kubaluleke kakhulu.I-Hangzhou Dali ineminyaka engaphezu kwengama-20 yesipiliyoni sokuthuthukiswa kwemboni, izixazululo ezinzile futhi ezisebenzayo zokwelashwa kwamanzi, futhi yakha inani lamakhasimende nomphakathi njalo.

Ukuze kuthuthukiswe izinsiza zamanzi ngendlela enengqondo, ukuchithwa kwamanzi olwandle kuyindlela ebalulekile.Ngenxa yokuthi kulula ukuthatha amanzi olwandle, ubuchwepheshe obuvuthiwe, ukusetshenziswa okuphezulu kanye nezindleko ezifanele, kunganciphisa ngempumelelo ukushoda kwamanzi kubantu, amadolobha, izimboni kanye nezolimo.Sekuyisinqumo esivamile kohulumeni abaningi, izifunda kanye namabhizinisi ukuxazulula inkinga yokushoda kwamanzi.Izixazululo zobuchwepheshe ze-Hangzhou Dali zokukhipha usawoti emanzini olwandle ziye zaqashelwa amakhasimende amaningi ngenxa yokusebenza kahle nokwethembeka kwazo.
