Nekukura kuri kuita maindasitiri, makemikari, mishonga, kudhinda nekudhaya, kugadzira mapepa nemamwe maindasitiri kuri kuramba kuchikura. Zvisinei, huwandu hwakawanda hwemakemikari nezvinhu zvinoshandiswa mukugadzirwa kwemaindasitiri aya, uye zvinhu izvi zvinogona kusangana nemvura panguva yekugadzira kugadzira mvura yakasviba ine huwandu hwakawanda hwezvinosvibisa. Nekuda kwekuwanda kwezvinosvibisa mumvura yakasviba ine huwandu hwakawanda hwezvinosvibisa, nzira dzechinyakare dzekurapa dzinowanzo kuve dzakaoma kubvisa zvinobudirira, saka michina yekurapa mvura yakasviba ine huwandu hwakawanda hwezvinosvibisa inodiwa.
Kurapa mvura yakasviba ine huwandu hwakawanda hwemvura kwakakosha zvikuru nekuti rudzi urwu rwemvura yakasviba rune huwandu hwakawanda hwezvinhu zvine chepfu uye zvine njodzi, izvo zvinokanganisa nharaunda zvakanyanya kana zvikaburitswa zvakananga munzvimbo yakapoteredza. Pamusoro pezvo, mvura yakasviba ine huwandu hwakawanda inogonawo kutyisidzira hutano hwevanhu uye inogona kutungamira mukuitika kwezvirwere zvakasiyana-siyana.
Nzira dzekurapa nemuviri dzinosanganisira nzira dzakadai sedimentation, filtration uye centrifugal separation yekubvisa zvidimbu zvakasungirirwa uye zvakasimba kubva mumvura yakasviba. Nzira dzekurapa nemakemikari, kune rumwe rutivi, dzinoshandisa makemikari ekugadzirisa kana kubvisa zvinhu zvine njodzi mumvura yakasviba, zvakaita seacid-base neutralization uye oxidation-reduction. Nzira dzekurapa nemakemikari dzinoshandisa metabolism yetupukanana kuti tuparadze organic matter kuita zvinhu zvisina njodzi.
Kushandisa michina yekuchenesa mvura yakasviba yakawanda hakungobatsiri chete kuchengetedza nharaunda, asiwo kunochengetedza mari yebhizinesi. Kuburikidza nekurapa mvura yakasviba zvinobudirira, zvinogona kuderedza mari yetsvina yebhizinesi, uye panguva imwe chete, kuwana zviwanikwa zvinobatsira mumvura yakasviba uye kuwedzera mwero wekushandiswa kwezviwanikwa.
Muchidimbu, michina yekurapa mvura yakasviba yakawanda inokosha zvikuru pakuchengetedza nharaunda nekusimudzira budiriro inoenderera mberi. Nekuvandudzika kuri kuramba kuchiitwa kweruzivo rwekuchengetedzwa kwezvakatipoteredza, rudzi urwu rwemidziyo ruchashandiswa zvakanyanya muminda yakawanda.
