Japan, pamusoro pekuve nyika inomiririrwa nesainzi yekucheka, zvakare inyika ine zvinodiwa zvakanyanya zvehunyoro mumunda wehupenyu hwepamba. Kutora munda wezuva nezuva wemvura yekunwa semuenzaniso, Japan yakatanga kushandisapombi dzesimbi dzisina tsvinasepombi dzemvura dzemumaguta muna 1982. Nhasi, chikamu chepombi dzemvura dzesimbi isina tsvina dzinoshandiswa muTokyo, Japan dzakakwirira kudarika 95%.
Nei Japan ichishandisa pombi dzesimbi dzisina simbi pamwero mukuru mumunda wekufambisa mvura yekunwa?
Gore ra1955 risati rasvika, mapaipi emarara aiwanzoshandiswa mupombi dzepombi dzemvura dzepombi muTokyo, Japan. Kubva muna 1955 kusvika muna 1980, pombi dzepurasitiki uye pombi dzesimbi-yepurasitiki dzakasanganiswa dzakashandiswa zvakanyanya. Kunyangwe hazvo matambudziko emhando yemvura uye matambudziko ekuvuza kwepombi dzakagadziriswa akagadziriswa zvishoma, kubuda mumvura kweTokyo kuchiri kwakakomba, nehuwandu hwekudonha hwasvika pa40% -45% isingagamuchirwe muma1970s.
The Tokyo Water Supply Bureau yakaita ongororo yakadzama pamatambudziko ekudonha kwemvura kweanopfuura makore gumi. Maererano nekuongorora, 60.2% yemvura inoputika inokonzerwa nekusakwana kwesimba remvura pombi zvinhu uye kunze kwemasimba, uye 24.5% yemvura inoputika inokonzerwa nekugadzirwa kusinganzwisisike kwemajoini epombi. 8.0 % yekudonha kwemvura kunokonzerwa nekusanzwisisika kwepombi nzira dhizaini nekuda kwekuwedzera kwekuwedzera kwemapurasitiki.
Kuti izvi zviitike, iyo Japan Waterworks Association inokurudzira kuvandudza zvinhu zvepombi dzemvura uye nzira dzekubatanidza. Kutanga kubva muna Chivabvu 1980, pombi dzese dzemvura dzine dhayamita isingasviki 50 mm kubva pamutsetse mukuru wemvura webetsero kuenda kumita yemvura dzichashandisa pombi dzemvura dzesimbi isina tsvina, majoini epombi, magokora uye pombi.
Zvinoenderana nenhamba kubva kuTokyo Water Supply Department, sezvo mwero wekushandiswa kwesimbi isina tsvina wakawedzera kubva pa11% muna 1982 kusvika kupfuura 90% muna 2000, huwandu hwekudonha kwemvura hwakadzikawo kubva pa50,000 pagore mukupera kwema1970 kusvika 2-3 mu2000 dambudziko remvura yekunwa.
Nhasi muTokyo, Japan, pombi dzemvura dzesimbi dzisina simbi dzakaiswa munzvimbo dzose dzinogara vanhu, izvo zvakavandudza zvikuru kunaka kwemvura uye kuwedzera kusavapo kwekudengenyeka kwenyika. Kubva pakushandiswa kwepombi dzemvura dzesimbi isina tsvina muJapan, tinogona kuona kuti zvakanakira pombi dzemvura dzesimbi isina tsvina maererano negirinhi kuchengetedzwa kwezvakatipoteredza, kuchengetedza zviwanikwa, uye hutano nehutsanana hazvina mubvunzo.
Munyika yedu, pombi dzesimbi dzisina simbi dzakatanga kushandiswa muindasitiri yemauto. Mushure memakore anoda kusvika makumi matatu ebudiriro, tekinoroji yechigadzirwa yakavandudzwa zvakanyanya, uye zvishoma nezvishoma yakapinda mundima yekufambisa mvura yekunwa, uye yakasimudzirwa nesimba nehurumende. Musi waChivabvu 15, 2017, Bazi reDzimba neKumaruwa-Kumaruwa kuChina rakapa "Direct Drinking Water Pipeline yeZvivakwa neNzvimbo dzekugara" System Technical Regulations ", iyo inoti mapombi anofanirwa kugadzirwa emhando yepamusoro yepombi dzesimbi isina tsvina. Pasi pefomu iri, China yakabereka boka revamiriri vemakambani ehurumende akazvimirira uye hunyanzvi hwemakambani ehurumende.
