Nekukura kweindasitiri yezvekurapa uye kukwegura kwevanhu, masangano ezvekurapa anogadzira mvura yakasviba yakawanda. Kuti vadzivirire nharaunda nehutano hwevanhu, hurumende yakaburitsa mitemo nemirau yakati wandei, ichida kuti masangano ezvekurapa aise nekushandisa michina yekurapa mvura yakasviba, aite kurapwa kwakasimba uye kubvisa utachiona mumvura yakasviba kuitira kuti ive nechokwadi chekuti inosangana nezvinodiwa pakuburitsa mvura.
Mvura yakasviba yekurapa ine huwandu hwakawanda hwetupukanana tunokonzera zvirwere, zvisaririra zvemishonga uye zvinosvibisa makemikari, uye kana ikaburitswa zvakananga pasina kurapwa, ichakonzera kukuvadza kukuru nharaunda nehutano hwevanhu.
Kuti pasave nekukuvadzwa kwezvakatipoteredza nehutano hwevanhu kunokonzerwa nemvura yakasviba yekurapa, kudiwa kwemidziyo yekurapa mvura yakasviba yekurapa kunonyanya kukosha. Midziyo yekurapa mvura yakasviba yekurapa inogona kubvisa zvinhu zvinokuvadza mumvura yakasviba yekurapa uye kuita kuti isvike padanho renyika. Midziyo iyi inowanzoshandisa nzira dzekurapa dzemuviri, makemikari uye zvehupenyu, dzakadai sedimentation, filtration, disinfection, biochemical treatment, nezvimwewo, kubvisa zvinhu zvakamiswa, organic matter, pathogenic microorganisms, radioactive substances, nezvimwewo kubva mumvura yakasviba.
Muchidimbu, kukosha kwemidziyo yekurapa mvura yakasviba hakugoni kuregeredzwa. Masangano ekurapa anofanira kukoshesa zvikuru kurapwa kwemvura yakasviba yekurapa, kuisa nekushandisa michina yekurapa yakakodzera kuitira kuti mvura yakasviba yekurapa ibude zvinoenderana nemutemo, uye kuiswa nekushandiswa kwemidziyo yekurapa mvura yakasviba ibasa repamutemo uye renzanga remasangano ekurapa. Panguva imwe chete, hurumende neveruzhinji vanofanirawo kusimbisa mutemo nekuzivisa veruzhinji nezvekuchengetedzwa kwezvakatipoteredza, izvo zvinovawo danho rakakosha rekuchengetedza hutano hwevanhu nekuchengetedzeka kwezvakatipoteredza.
Midziyo yekuchenesa mvura yakasviba iri mumidziyo inoshandisa UV disinfecting, iyo inonyanya kupinda uye inogona kuuraya 99.9% yemabhakitiriya, kuitira kuti mvura yakasviba inogadzirwa nezvipatara ishandiswe zvakanaka uye kuchengetedza hutano.
