Kutshanje, umzi-mveliso wethu uphumelele ngempumelelo uvavanyo lokuvuza kwamanzi lwesango lesikwere le-sluice elenziwe ngesandla leemveliso ezenzelwe wena, nto leyo ebonisa ukuba ukusebenza kokuvala kwesango kuye kwahlangabezana neemfuno zoyilo. Oku kungenxa yokucwangcisa ngononophelo kunye nokwenziwa kokukhethwa kwezinto zethu, inkqubo yokuvelisa kunye nokuhlolwa komgangatho. Oku kukwabonakalisa umoya weqela lethu. Ukususela kubayili ukuya kubasebenzi bomgca wemveliso, ukusuka kubahloli bomgangatho ukuya kubaphathi beeprojekthi, ubuchule kunye nomsebenzi onzima womntu wonke ubaluleke kakhulu. Baqinisekisa ukuba yonke into igqibelele, ukuze yonke imveliso ikwazi ukumelana novavanyo lokusetyenziswa okusebenzayo.

Umahluko ophambili phakathiisango lesikwere se-sluiceixabiso kunye nesango eliqhelekileyo lixhomekeke kuyilo lwazo lwesakhiwo kunye neemeko zokusetyenziswa. Isango lesikwere, njengoko igama laso lisitsho, linecandelo elinqamlezileyo lesikwere, elenza libe ngcono ukutywina nokuba kumacala athe nkqo okanye athe tye. Isango eliqhelekileyo linokubhekisa kwisango lendabuko elithe tyaba okanye eligobileyo, elisetyenziswa kakhulu kubunjineli be-hydraulic, kodwa kwindawo ethile yokusetyenziswa, ukusebenza kwalo kokutywina kusenokungabi kuhle njengesango lesikwere.

Uyilo lwesakhiwo sesikwere lwenza isango le-channel sluice lizinze ngakumbi xa liphantsi koxinzelelo, linokumelana ngempumelelo nempembelelo yangaphandle kunye noxinzelelo lwamanzi, kwaye landisa ubomi benkonzo ye-I-Penstockisango. Isango lesikwere lingasetyenziswa ngesandla, ngombane okanye ngamanzi ukuze kuhlangatyezwane neemfuno zeendawo ezahlukeneyo zokusebenza. Ingakumbi kwimveliso yemizi-mveliso yanamhlanje enezinga eliphezulu lokuzenzekela, ivalvu yesango lesikwere le-sluice esetyenziswa ngombane okanye ngamanzi inokuphucula ukusebenza kakuhle kunye nokhuseleko.

Olu vavanyo lokuvuza kwamanzi oluphumeleleyo lubonakalisa amandla ethu okuvelisa iimveliso ezikumgangatho ophezulu ngokuhambelana nemigangatho ephezulu, kodwa lukwasikhumbuza ukuba uphuhliso oluqhubekayo lwetekhnoloji kunye nokuphuculwa komgangatho yingongoma engunaphakade yophuhliso lweshishini, luqinisekiso lwamandla ethu obuchwephesha kunye nenkqubo yolawulo lomgangatho. Njengoko itekhnoloji iqhubeka ihambela phambili kwaye iimfuno zemarike zitshintsha, inkqubo yoyilo kunye nemveliso yamasango ezikwere zezikhukula iya kuqhubeka iphuculwa ukuze ihlangabezane neemfuno zamashishini amaninzi ukuze kubekho izisombululo zolawulo lolwelo ezisebenzayo nezithembekileyo.
