Iyunithi yempompo yamanzi luhlobo lwezixhobo ezishukumayo, ikakhulu ezenziwe nge-injini ye-diesel, impompo yamanzi, itanki yamafutha kunye nenkqubo yokulawula.Isebenzisa i-injini ye-diesel ukuqhuba impompo yamanzi ukuphefumlela umthombo wamanzi, kwaye emva koko iwathuthe kwindawo efunekayo ngombhobho.Isetyenziswa ngokuqhelekileyo kule mimandla ilandelayo:
1 Ukunkcenkceshela kwezolimo: Iyunithi yempompo yamanzi inokubonelela ngomthombo wamanzi othembekileyo wokunkcenkceshela kwezolimo, ukuze umhlaba wokulima unkcenkceshelwe ngokupheleleyo kwaye ugcine isivuno esihle ngexesha lonyaka elomileyo.
I-2 Amanzi amashishini: Iiyunithi zempompo zamanzi zisetyenziswa ngokubanzi kwiimeko ezahlukeneyo zamanzi zoshishino, ezifana nokulungiswa kwezinto eziluhlaza, ukuhamba kwenkqubo, inkqubo yokukhusela umlilo, njl., Ukuqinisekisa ukunikezelwa kwamanzi okwaneleyo.
3 Iindawo zokwakha: Iiyunithi zempompo zamanzi zisetyenziswa kakhulu kwiindawo zokwakha, kwaye zingasetyenziselwa ukuxuba ikhonkrithi, ukukhutshwa kwamanzi kwiindawo zokwakha, ukupholisa isitshizi kunye namanye amasimi.
I-4 Ukucima umlilo kunye nokuhlangula: Iyunithi yempompo yamanzi ngokuqhelekileyo enye yezixhobo eziqhelekileyo zesebe lomlilo, ezinokubonelela ngokukhawuleza imithombo yamanzi eyaneleyo kwiimeko ezingxamisekileyo ezifana nomlilo kunye nezikhukhula ukukhawuleza ukucima umlilo okanye ukuhlangula abasebenzi.
5 Ukuhanjiswa kwemingxuma emigodini: Kweminye imigodi engaphantsi komhlaba, itonela kunye neeprojekthi eziphantsi komhlaba, ukumpompa nokukhupha amanzi ngokuqhelekileyo kuyafuneka ukuze kugcinwe inkqubela eqhelekileyo yeprojekthi, kunye neyunithi yokumpompa amanzi inokubonelela ngenkxaso eyomeleleyo kwezi ndawo.
Ngamafutshane, iyunithi yempompo yamanzi isetyenziswa ngokubanzi kwiinkalo ezininzi ezifana nezolimo, imboni, ukwakhiwa, ukukhuselwa komlilo, ukuhlangula, ukumbiwa kwemigodi, njl.
