Iyunithi yephampu yamanzi iwuhlobo lwemishini ehambayo, ikakhulukazi eyakhiwe injini yedizili, iphampu yamanzi, ithangi likaphethiloli kanye nohlelo lokulawula.Isebenzisa injini ye-diesel ukushayela iphampu yamanzi ukuze ihogele umthombo wamanzi, bese iwahambisa endaweni edingekayo ngepayipi.Isetshenziswa kakhulu emikhakheni elandelayo:
1 Ukuchelela kwezolimo: Iyunithi yepompo yamanzi inganikeza umthombo wamanzi onokwethenjelwa wokunisela kwezolimo, ukuze indawo yokulima iniselwe ngokugcwele futhi igcine isivuno esihle ngenkathi eyomile.
2 Amanzi ezimbonini: Amayunithi epompo yamanzi asetshenziswa kakhulu ezikhathini zamanzi ezehlukene zezimboni, njengokucutshungulwa kwempahla eluhlaza, ukugeleza kwenqubo, uhlelo lokuvikela umlilo, njll., ukuze kuqinisekiswe ukutholakala kwamanzi anele.
3 Izindawo zokwakha: Amayunithi ephampu yamanzi asetshenziswa kakhulu ezindaweni zokwakha, futhi angasetshenziswa ekuxubeni ukhonkolo, ukuchithwa kwamanzi ezindaweni zokwakha, ukupholisa isifutho nezinye izinkambu.
4 Ukucima umlilo nokuhlenga: Iyunithi yephampu yamanzi imvamisa ingenye yezinto ezijwayelekile zomnyango wezomlilo, ezingahlinzeka ngokushesha ngemithombo yamanzi eyanele ezimeni eziphuthumayo ezifana nemililo nezikhukhula ukuze kusheshiswe izicishamlilo noma izisebenzi zokuhlenga.
5 Ukuthuthwa kwamanzi emayini: Kwezinye izimayini ezingaphansi komhlaba, imigudu namaphrojekthi angaphansi komhlaba, ukumpompa nokukhipha amanzi ngokuvamile kuyadingeka ukuze kugcinwe inqubekelaphambili evamile yomsebenzi, futhi iyunithi yephampu yamanzi inganikeza ukwesekwa okuqinile kulezi zindawo.
Ngamafuphi, iyunithi yepompo yamanzi isetshenziswa kabanzi emikhakheni eminingi efana nezolimo, imboni, ukwakhiwa, ukuvikela umlilo, ukuhlenga, izimayini, njll. Kuyinto esebenza kahle futhi enokwethenjelwa yomthombo wamanzi weselula.
