Okwangoku, xa ukumakishwa kweumatshini wokuqhushumba wamanzi anoxinzelelo oluphezuluiyacinywa, ngenxa yokuba eminye imisebenzi nayo ineemfuno eziphakamileyo neziphezulu zokhuseleko lokusingqongileyo, indlela yokumakisha ijethi yamanzi enoxinzelelo oluphezulu iye yavela ngeli xesha lembali, kwaye ibe luhlobo lokumakisha oluthandwa ngamazwe aseYurophu naseMelika kwiminyaka yakutshanje.Indlela yokucoca, oomatshini bokwakha abaphambili ngumatshini wokumakisha ijethi yamanzi oxinzelelo oluphezulu.Umatshini wokuhlamba usebenzisa inkqubo yoxinzelelo ukwenza amanzi akhutshwe kwi-nozzle.Le jethi yamanzi inempembelelo enamandla kunye namandla okusika, anokungena ngokuthe ngqo kwiipores ze-asphalt ukususa ipeyinti yokumakisha.I-pavement ecocekileyo ayicocwanga kuphela yindlela yokususa ijethi yamanzi aphezulu, kukho nayiphi na intsalela yepeyinti yokumakisha, kwaye akuyi kubakho monakalo, kwaye yonke i-pavement iya kuhlambuluka kakhulu.Umatshini oqhelekileyo omncinci woxinzelelo oluphezulu lwejethi yamanzi uya kuvelisa inani elikhulu lamanzi amdaka ngexesha lomsebenzi wokucoca.La manzi anokubangela i-pavement engacocekanga okanye angene kwimingxunya ye-asphalt ukuze enze umonakalo kwizinto zepavumente.Ngoko ke, inkqubo yokucoca kufuneka ixhotyiswe ngezixhobo ezifanelekileyo zokuCoca.Okwangoku, ukuyila koomatshini bokucoca ijethi yamanzi aphantsi koxinzelelo oluphezulu lunobunkunkqele kwaye luxhotyiswe ngokupheleleyo.Ngokomzekelo, kukho isixhobo sokucoca kwi-nozzle ye-high-pressure water gun, ngoko ayiyi kuchaphazela indawo yendlela.Uxinzelelo lwenkqubo lunokulungelelaniswa ukufezekisa ukucocwa kwepeyinti eyahlukileyo yokuMakisha.
