Ngaphakathi kwengqalasizinda yesimanje ye-hydrological, ikakhulukazi ezinhlelweni zamadamu namadamu, isango le-wall penstock sluice limi njengendlela ebalulekile yokulawula amanzi ngendlela efanele. Lesi sakhiwo esikhethekile, esivame ukubizwa ngokuthi ama-valve e-penstock odongeni noma i-valve ye-penstock efakwe odongeni, yakhelwe ukulawula ukuphuma kwamanzi ngesango elishelelayo eliqondile noma elivundlile elihlanganiswe kukhonkolo noma izakhiwo zamatshe. Izindlela zokusebenza zisukela ezinhlelweni zesango le-penstock manual-ezilungele izinhlelo zokusebenza ezihamba kancane ezidinga ukulawulwa komuntu okuqondile-kuya ekusethweni okuthuthukisiwe okuzenzakalelayo, okuvumela ukulungiswa okunembile kwamazinga amanzi kanye namazinga okugeleza ukuhlangabezana nezidingo zokusebenza.

Njengetshe legumbi lobunjiniyela be-hydraulic, isango le-penstock sluice gate liyisibonelo sokuhlanganisa ukunemba, ukuqina, nokuvumelana nezimo. Ukuthi lisebenza njengesango le-penstock elisebenza ngesandla ekuniselelweni kwezinga elincane noma i-automated wall penstock valve emadamini amakhulu aphehla ugesi ngamanzi, indima yalo ekulinganiseni ukutholakala kwamanzi, ukuvimbela izikhukhula, kanye nokuthuthukisa ukuphepha kwesakhiwo kuhlala kungenakuqhathaniswa.
