Kuchinja Kwemamiriro ekunze uye Kukurumidza Kukurumidza kweindasitiri yepasi rose uye kurima kwakaita kuti dambudziko rive rekushayikwa kwemvura mitsva kuri kuwedzera simba, uye kuwanikwa kwemvura mitsva kuri kuwedzera nguva, kuitira kuti mamwe maguta emahombekombe ari mapfupi emvura. Dambudziko remvura rinomisa kudiwa kusiri kusarudzika kusuwa kwegungwa. Midziyo yeMembrane yekushandisa mune iyo yemvura yemvura inopinda kuburikidza neyekupindwa kwemvura yekumanikidza, iyo yakadzvanywa mumvura yakakwirira yekumanikidza.

Maererano neNyika Bureau yehuwandu, huwandu hwese hwemvura nyowani muChina yaive 2830.6billion cubic metres muna 2015, accounting kweanenge 6% yezvinhu zvemvura yeGlobal, chinzvimbo chechina chiri munyika. Nekudaro, iyo per capita yemvura yemvura inowanikwa ingori mazana maviri nemakumi matatu emakumi matatu emakumi maviri emamita, ayo ari chete 1/35 of the World average, uye pane kushomeka kwemvura yakachena yemvura. Nekuwedzera kwekushanda kwekushanda uye urbanization, mvura yakachena mvura inonyanya kukonzeresa kumisikidzwa marara uye maguta emba. Kusuwa kwemvura yegungwa inotarisirwa kuve nzira huru yekuwedzera mvura yakakwirira yekunwa. China yemvura yegungwa desication indasitiri shandisa maakaundi 2/3 yehuwandu. Kubva munaDecember 2015, Swillater Desalation Projects 139 Yakavakwa Nyika Yese, ine huwandu hwe110265million ton / zuva. Maindasitiri emvura maAccount e63.60%, uye anogara mvura maakaunti e 35.67%. Iyo Global Dsalination Project inonyanya kunoshanda mvura yekugara (60%), uye mvura indasitiri inongova maakaundi 28%.

Chinangwa chakakosha chekuvandudza kwesarudzo yegungwa dema Mukuumbwa kwemari yekushandisa, magetsi emagetsi ekushandisa maakaunti akakura chikamu. Kuderedza kushandiswa kwesimba ndiyo inonyanya kushanda nzira yekudzikisa mvura yegungwa desalination.
