    Tinofara kutanga zvigadzirwa zvedu zvitsva zvesimbi, zvakagadzirirwa kupa mashandisirwo akanaka kwazvo, kunyanya macofferdams. Mapombi aya ane dhizaini yakakombama kana yakatenderera inopindirana kuti ive nesimba risingaenzaniswi uye inogara kwenguva refu, ichivhara uye ichidzivirira kupinda kwemvura, ivhu nejecha.

    Yedupombi yakasungirirwa dhayamita hombesndiwo musimboti wemapombi aya esimbi, zvichiwedzera kuvimbika kwawo uye kushanda kwawo. Kuburikidza nekunatsiridza kwakanyatsogadzirwa uye maitiro ekudzora mhando, tinoona kuti pombi yega yega inosangana nezvinodiwa zvepamusoro-soro zveindasitiri. Mapombi aya anopa kuchinjika kwakanyanya uye kugara kwenguva refu, zvichibvumira pombi dzesimbi kuti dzikwanise kumira mumamiriro ezvinhu akaomarara uye munzvimbo dzakaoma.

    Fekitori yedu ine matani 400,000 emapaipi esimbi anotenderera pagore uye mutengo wemari inosvika mabhiriyoni 1.8 eyuan. Izvi zvinoratidza kuzvipira kwedu kupa basa rakanaka uye kusangana nezvinodiwa nevatengi vedu vanokosha munharaunda nepasi rose.

    Mapombi esimbipamwe chete nemapombi edu akasungirirwa akakura nedhayamita anopa hunyanzvi hwakanaka, zvichiita kuti akwanise kushandiswa zvakasiyana-siyana. Pamusoro pemapombi eCofferdams, mapombi edu anoshandiswa zvakanyanya mukuvaka mabhiriji, zvivakwa zvechiteshi uye mamwe mapurojekiti egungwa. Dhizaini yakasiyana yemapambi aya inoita kuti mvura nevhu zvirambe zvakaringana uku ichipa chimiro chakasimba.

    Kuzvipira kwekambani yedu kune mhando, hunyanzvi uye kugutsikana kwevatengi kunotikurudzira kuti tirambe tichivandudza maitiro edu ekugadzira uye kugadzira mhinduro itsva. Tinotevedzera mitemo yakasimba yekudzora mhando kuitira kuti tive nechokwadi chekuti zvigadzirwa zvedu ndezvemhando yepamusoro uye zvinosangana kana kupfuura zvaunotarisira.
