Ukusika i-Waterjet ubuchwepheshe obuthuthukisiwe obusebenzisa ukugeleza kwamanzi anengcindezi ephezulu kanye nengxube ehuqayo ukusika izinto. Ngokuxuba amanzi nama-abrasives bese uwacindezela, kwakhiwa i-jet yesivinini esikhulu, futhi i-jet isetshenziselwa ukuphazamisa umsebenzi wokusebenza ngesivinini esikhulu, ngaleyo ndlela kuzuzwe ukusika nokucubungula izinto ezihlukahlukene.
Ukusika indiza yamanzi kusetshenziswa kakhulu endaweni yendiza, ukukhiqiza izimoto, izinto zokwakha kanye neminye imikhakha. Emkhakheni we-aerospace, ukusika i-jet yamanzi kungasetshenziswa ukusika izingxenye zezindiza, njenge-fuselage, amaphiko, njll, ukuqinisekisa ukunemba kanye nekhwalithi yezingxenye. Ekwenziweni kwezimoto, ukusika i-waterjet kungasetshenziswa ukusika amaphaneli omzimba, izingxenye ze-chassis, njll., ukuqinisekisa ukunemba nokubukeka kwekhwalithi yezingxenye. Emkhakheni wezinto zokwakha, ukusika ijethi yamanzi kungasetshenziswa ukusika imabula, i-granite nezinye izinto ukuze kuzuzwe ukuqoshwa nokusika okuhle.
