E-Afrika nase-Asia, Abantu abayizigidi ze-750 abanakho ukufinyelela okwanele kwamanzi okuphuza. Ukuze kulethwe amanzi emindenini yabo, abesifazane nezingane ngezikhathi ezithile kudingeka ukuthi bahambe amabanga amade, afinyelela kumakhilomitha ayisithupha ubude, namabhakede angama-6 litre abawathwala emakhanda abo. Le nqubo, ngaphandle nje kokuthatha isikhathi, ibuye ibe yingozi empilweni, njengoba ibanga izinkinga zemisipha.
I-Hippo Water Roller iyisinyathelo esimangalisayo nesijabulisayo njengesisombululo esilula sokunciphisa lezi zinkinga zokuthola amanzi. Ngesisindo esisebenzayo samakhilogremu ayi-10 kuphela, umgqomo wamanzi onamasondo uvumela abantu ukuthi thwala amalitha amanzi angama-90 ngasikhathi sinye, okuvame ukuba cishe ngokuphindwe kahlanu kunalokho okungathwalwa ngebhakede. Lokhu kwenza ukuthuthwa kwamanzi kusheshe futhi kube lula.
Umgqomo wenziwe nge isiqeshana esisodwa esiqinile yenziwe ngepulasitiki elukhuni engathwalwa ngomhlabathi oklwebhe kakhulu futhi inekhono lokuhlanza amanzi ngesihlungi. Ibuye inikeze ithuba lokuyisebenzisela ukunisela izingadi ezincane. Uhlaka lwensimbi yangokwezifiso luvumela umgqomo ukuthi uphendulwe isondo.
I-Hippo Roller ngayinye yenzelwe ugcine cishe iminyaka engu-7 Futhi uma impilo yawo yokusebenziseka isiphelile, ingabuye isetshenziselwe ezinye izinsiza ezifana nomgqomo wokuwasha noma wokugcina ezinye izinhlobo zezinto.
Lo mklamo wenziwa onjiniyela uPettie Petzer noJohan Jonker abakhulele emapulazini futhi bazibonela mathupha inkinga yamanzi emiphakathini yasemakhaya. Manje ukusungulwa kwakhe kuyenzeka isetshenziswe emazweni angama-20 ezwenikazi i-Afrika futhi kunama-roller angama-45.000 asatshalaliswe kubantu abangaphezu kwama-300.000 emhlabeni jikelele, kubandakanya i-India neNingizimu Melika.
Okunye okuhle okusunguliwe lomfana.
