Lo ngumatshini wokucoca itreyi yeetunnel ezimbini. Abantu ababini babeka iitreyi ezingcolileyo kwindawo yokufaka. Emva kokucoca ngoxinzelelo oluphezulu, ukucoca isepha, ukucoca ngoxinzelelo oluphezulu ngamanzi abandayo, ukuhlamba, nokungena kwicandelo lokukhupha amanzi ngemela yomoya, ngeli nqanaba, i-60-70% yamanzi isuswa yifeni yoxinzelelo oluphezulu, emva koko kwenziwa inqanaba lokomisa. Kweli nqanaba, i-20-30% eseleyo yamanzi inokususwa ngokomisa ngobushushu obuphezulu, nto leyo efezekisa ukomisa okusisiseko. Lo mgca wemveliso usebenzisa uyilo lweetunnel ezimbini, nto leyo efezekisa isiphumo sokukhupha esiphindwe kabini. Ngelixa iqinisekisa imveliso, ifezekisa ukonga abasebenzi, ukonga ixesha, kunye nokonga abasebenzi.
