Iimpompozizixhobo zoomatshini eziqhelekileyo zokuthutha nokuphakamisa ulwelo. Zixhomekeke ekuguqulweni kwamandla oomatshini ukuze kufezekiswe ukuthuthwa, uxinzelelo kunye nokujikeleza kwamanzi kunye neendlela ezahlukeneyo zokusasaza. Zizixhobo ezisisiseko eziyimfuneko kwicandelo lemizi-mveliso, indlela yokuphila yabantu kunye nezolimo.

Ngokwalo msebenzi, isiseko sinemisebenzi emihlanu ephambili: ukuthuthwa kolwelo, ukuhanjiswa kwamanzi axinzelelweyo, ukutshintshiselana kobushushu obujikelezayo, amanzi amdaka kunye nokutsalwa kwamanzi, kunye nokulawula umgangatho wolwelo. Ingathutha amanzi acocekileyo, amanzi amdaka, amanzi eoyile kunye nemidiya ebolileyo kancinci, kwaye ihlangabezane neemfuno zeemeko zokusebenza ezahlukeneyo ezifana nokuthuthwa koxinzelelo oluphantsi, ukutshiza koxinzelelo oluphezulu kunye nokuthuthwa kwamanzi okude.

Iindlela zokusetyenziswa zibanzi: isetyenziselwa ukubonelela ngamanzi aphezulu kwizakhiwo zikawonke-wonke, ukubonelela ngamanzi kunye nokutsalwa kwamanzi kwiindawo zokuhlala, kunye nokujikeleza kwamanzi kwindawo yomoya opholileyo ephakathi. Isetyenziswa kwintsimi yezolimo ukunkcenkceshela amasimi, ukuphambuka kwamanzi emilanjeni, ukuhambisa amanzi ezikhukula kunye nokumelana nembalela. Iindlela zoshishino zifanelekile kumanzi ajikelezayo emizi-mveliso, uthutho oluphakathi lweekhemikhali, amanzi okutya ebhoyila, kunye nonyango lwelindle. Ubunjineli bukamasipala busetyenziselwa ukukhupha amanzi amdaka ezidolophini, ukuhambisa amanzi emvula, kunye neempawu zamanzi kwiindawo zegadi. Ukongeza, isetyenziswa kakhulu kwiimeko ezifana nokuhambisa amanzi emigodini, ukunyuka koxinzelelo lokulwa nomlilo, kunye nokukhupha ityuwa emanzini olwandle, ukuhlangabezana neemfuno zokuhambisa amanzi kunye nokunyuka koxinzelelo kwiindawo ezahlukeneyo.
