Ubuchwepheshe Bangemuva:

Njengamanje, ikesi lamanzi emakethe ikakhulukazi ikesi lethusi, liqukethe ukuhola kwensimbi okungeyona eyensimbi, ukusetshenziswa kwesikhathi eside kuzovela ukugqwala kwethusi, futhi ukuhola kuyingozi empilweni yabantu, enyakatho yezindawo ezibandayo, ngoba amandla ukwakheka kwegobolondo lethusi akukukhulu, isikhathi eside kuvame ukuvela ukuqhekeka kwegobolondo nokubanda.

Ukuze uxazulule izinkinga zobuchwepheshe ezingenhla, imodeli yokusetshenziswa ihlose ukuhlinzeka ngecala lewashi lamanzi lensimbi elinokumelana nokugqwala namandla aphezulu. Ikesi lokubuka amanzi lensimbi elingenasici lemodeli yokusetshenziswa liqukethe igobolondo lensimbi engagqwali, uhlangothi olulodwa lwegobolondo lensimbi elingenalutho luhlinzekwa nge-eneji yamanzi, enye ingxenye yegobolondo lensimbi engagqwali inikezwa indawo yokuhambisa amanzi, i-valve yokulawula amanzi ishiselwe emanzini, bese kunyakaza imitha yamanzi emzimbeni womgodi phezulu kwegobolondo lensimbi engagqwali. Icala lemitha lamanzi lensimbi elingenasici lemodeli yokusetshenziswa lilungiswa kukesi lensimbi engagqwali ngokushisela noma ngokuxhuma kwangaphakathi kwentambo. Okungena kwamanzi nokuphuma kwekesi lokubuka amanzi lensimbi engagqwali yemodeli yokusetshenziswa kwenziwa ngezinto zensimbi engagqwali. Uma kuqhathaniswa nobuciko bangaphambilini, imodeli yokusetshenziswa inezinzuzo ezilandelayo: 1. Umkhiqizo wenziwe ngensimbi engagqwali, unezinzuzo zamandla aqinile wesakhiwo, akukho kubanda nokuqhekeka, futhi kungasetshenziswa ngasolwandle, umhlaba ophakeme wama-alkali noma idolobha elibandayo enyakatho; 2, ngoba insimbi engagqwali ukumelana nokugqwala, ayinayo insimbi yomthofu, ingafinyelela indima yokuhlanzwa kwamanzi; 3. Ngoba yonke yenziwe ngepuleti lensimbi engagqwali, yenzelwa ukukhubazeka kwemigodi yesihlabathi esimweni sangaphambilini sokuphonsa futhi ivimbele ukuvuza kwamanzi

Imodeli yokusetshenziswa ihlobene nekesi lokubuka amanzi lensimbi elingenasici, eliqukethe igobolondo lensimbi engagqwali 1, umkhawulo owodwa wegobolondo lensimbi engagqwali ngihlinzekwa nge-inlet yamanzi 2, omunye umkhawulo wegobolondo lensimbi engagqwali ngilinikezwa ngamanzi i-outlet, i-valve control outlet control 3 ifakwa endaweni yokuphuma yamanzi, futhi ukunyakaza kwemitha yamanzi ku-4 kumiswe emgodini phezulu kwegobolondo lensimbi engagqwali.

Ukunyakaza kwemitha yamanzi 4 kulungiswe ezindlini zensimbi engagqwali ngokushisela noma ngokuxhuma intambo yangaphakathi. Lo mkhiqizo wenziwe ngensimbi engagqwali, amandla esakhiwo, ngeke uqandise ukuqhekeka, ungasetshenziswa ngasolwandle, umhlaba ophakeme wama-alikhali noma enyakatho yedolobha elibandayo; 2, ngoba insimbi engagqwali ukumelana nokugqwala, ayinayo insimbi yomthofu, ingafinyelela indima yokuhlanzwa kwamanzi; 3. Ngoba yonke yenziwe ngepuleti lensimbi engagqwali, yenzelwa ukukhubazeka kwemigodi yesihlabathi esimweni sangaphambilini sokuphonsa futhi ivimbele ukuvuza kwamanzi. Lokhu okungenhla kuphela imodi yokuqalisa ekhethwayo yemodeli yokusetshenziswa. Kufanele kuvezwe ukuthi, kochwepheshe abajwayelekile emkhakheni wezobuchwepheshe, ngaphandle kokwephula imigomo yezobuchwepheshe yemodeli yokusetshenziswa, ziningi izithuthukisi nokuhlukahluka okungenziwa, okuzophinde kuthathwe njengobubanzi bokuvikela imodeli yokusetshenziswa .
