Emkhakheni wezingubo zokugeza zezimboni, ukuqinisekisa ukuhlanzeka kwamalineni kubaluleke kakhulu, ikakhulukazi ezindaweni zezokwelapha lapho amazinga okuhlanzeka ebaluleke kakhulu. Izinhlelo zokuhlanza imisele zinikeza izixazululo ezithuthukisiwe zemisebenzi emikhulu yokuhlanza izingubo, kodwa indlela yokuhlanza esetshenziswayo ingathinta kakhulu ukuhlanzeka kwamalineni. Izinhlelo zokuhlanza imisele zisebenzisa izakhiwo ezimbili eziyinhloko zokuhlanza: "ukungena okukodwa kanye nokuphuma okukodwa" kanye "nokuhlanza okuphambene nogesi."
Isakhiwo "sokungena okukodwa kanye nokuphuma okukodwa" sihilela igumbi ngalinye lokuhlanza eliklanywe ngezindawo zokungena zamanzi ezizimele kanye nezindawo zokuphuma. Le ndlela, eyaziwa ngokuthi "isakhiwo sokuphuma okukodwa kanye nokuphuma okukodwa," iyasebenza ekugcineni ukuhlanzeka. Isebenza ngesimiso esifana nenqubo yokuhlanza kathathu esetshenziswa emishinini yokuwasha ezimele, iqinisekisa ukuthi igumbi ngalinye linokungena nokuphuma kwamanzi ahlanzekile, okusiza ekuhlanzeni kahle amalineni. Lo mklamo uthandwa kakhulu ngabahlanzi bemihubhe yezokwelapha.
Amalaphu ezokwelapha ahlukaniswe ngezinhlobo ezine eziyinhloko: izingubo zesiguli, izingubo zomsebenzi (kufaka phakathi amajazi amhlophe), izingubo zokulala, nezinto zokuhlinzwa. Lezi zigaba zinezici ezihlukile ngokombala nangezinto zokwakha. Isibonelo, amalaphu okuhlinzwa avame ukuba luhlaza okwesibhakabhaka futhi athambekele ekuphelelweni kombala kanye nokuchitheka kwe-lint ngesikhathi sokugeza okuyinhloko ngezinto zokushisa namakhemikhali. Uma kusetshenziswa isakhiwo sokuhlanza esiphikisana nogesi, amanzi okuhlanza asetshenziswa kabusha, aqukethe i-lint kanye nezinsalela zombala, angangcolisa amalaphu amhlophe. Lokhu kungcoliswa kungaholela ekutheni amalaphu amhlophe athole umbala oluhlaza kanye namalaphu okuhlinzwa aluhlaza anamathiselwe i-lint emhlophe. Ngakho-ke, ukuze kugcinwe amazinga aphezulu okuhlanzeka kanye nokuhlanzeka, imisebenzi yokuwasha izingubo zezokwelapha kumele isebenzise isakhiwo sokuhlanza "sokungena okukodwa kanye nokuphuma okukodwa".
Kulesi sakhiwo, amanzi okuhlanza amakhethini okuhlinzwa aphathwa ngokwehlukana ukuze kuvinjelwe ukungcoliswa okuphambeneyo. Amanzi asetshenziselwa ukuhlanza amakhethini okuhlinzwa angasetshenziswa kabusha kuphela ekugezeni amanye amakhethini okuhlinzwa, hhayi amalineni amhlophe noma ezinye izinhlobo. Lokhu kuhlukaniswa kuqinisekisa ukuthi uhlobo ngalunye lwelineni lugcina umbala walo kanye nokuhlanzeka okuhlosiwe.
Ngaphezu kwalokho, ukusebenzisa izindlela ezimbili zokukhipha amanzi kubalulekile ekuphathweni kwamanzi okuhle kakhulu. Enye indlela kufanele iqondise amanzi ethangini lokugcina amanzi ukuze asetshenziswe kabusha, kanti enye kufanele iholele epayipini lokuhambisa amanzi. Umshini wokucindezela osetshenziswa enkambisweni yokuwasha kufanele futhi ube nezindlela ezimbili zamanzi: enye yokuqoqa ithangi lokugcina amanzi kanye nenye yokulahla indle. Lolu hlelo oluphindwe kabili luvumela ukulahlwa kwamanzi anombala ngokushesha epayipini lokuhambisa amanzi, okuqinisekisa ukuthi awaxubani namanzi angasetshenziswa kabusha angenambala, angaqoqwa ethangini lokugcina amanzi ukuze asetshenziswe kamuva. Lolu hlelo lukhulisa imizamo yokonga amanzi futhi lugcina ikhwalithi yelineni.
Ingxenye ebalulekile yalolu hlelo ukufakwa kwesihlungi se-lint. Lesi sihlungi senzelwe ukususa imicu yendwangu emanzini, ukuqinisekisa ukuthi amanzi asetshenziswa kabusha enkambisweni yokuwasha awangcolile. Lokhu kubaluleke kakhulu ekugcineni ikhwalithi yokuwasha ilineni enemibala eminingi.
Nakuba izakhiwo zokuhlanza ezisebenzisa ugesi ophikisana nogesi zingasetshenziswa ekugezeni amalineni anemibala ehlukene, ziletha izinselele maqondana nokusebenza kahle kanye nokusetshenziswa kwamandla. Ukugeza imibala ehlukene ngokulandelana ngaphandle kokukhipha amanzi noma ukuhlukaniswa kahle kungaholela ekusetshenzisweni kwamandla okwandisiwe kanye nokusebenza kahle okuncishisiwe. Ukuze kuncishiswe lokhu, izindawo zokuhlanza zezokwelapha ezinevolumu ephezulu kanye nemishini eminingi yokuwasha imigudu zingahlela imisebenzi yazo yokuhlukanisa amalineni okuhlinzwa anemibala kwezinye izinhlobo zokulala. Le ndlela iqinisekisa ukuthi amalineni ombala owodwa ahlanzwa ndawonye, okuvumela ukusetshenziswa kabusha kwamanzi ngempumelelo kanye nokonga amandla okukhulu.
Ukwamukela isakhiwo sokuhlanza "sokungena okukodwa kanye nokuphuma okukodwa" kuma-washer e-tunnel yezokwelapha kuthuthukisa ukuhlanzeka kanye nokuhlanzeka kwelineni futhi kukhuthaza ukusetshenziswa kwamanzi namandla okusimeme. Ngokuphatha ngokucophelela inqubo yokuhlanza nokusebenzisa izinhlelo zokuhlunga ezithuthukisiwe, imisebenzi yokuhlanza izingubo zezokwelapha ingafinyelela amazinga aphezulu okuhlanzeka ngenkathi ithuthukisa ukusetshenziswa kwezinsiza.
