Kule mihla, ukuze kupheliswe impembelelo ekusetyenzisweni kwamanzi kwiindawo zokuhlala kubonelelo lwamanzi ezidolophini, imithetho efanelekileyo yobonelelo lwamanzi ezidolophini ebhalwe lilizwe lethu ayivumeli ukuba iimpompo zamanzi zasekhaya nezemveliso zifakwe ngqo kwinethiwekhi yemibhobho kamasipala. Izixhobo zobonelelo lwamanzi zabahlali ziqhagamshelwe kwinethiwekhi yemibhobho yobonelelo lwamanzi kamasipala ngokulandelelana, kwaye inkqubo yobonelelo lwamanzi olungenaxinzelelo kufuneka isetyenziswe. Umlawuli wokuhamba kwamanzi kunye netanki yokulungisa ukuzinza engaphantsi kwemiqolo kufuneka yongezwe phakathi kwendawo yokungena kwempompo kunye nenethiwekhi yemibhobho kamasipala. Umlawuli wokuhamba kwamanzi uhlala ejonga imibhobho kamasipala. Uxinzelelo olune-net. Ngelixa iqinisekisa ukuba inethiwekhi yemibhobho kamasipala ayivelisi uxinzelelo olune-negative, inokusebenzisa ngokupheleleyo uxinzelelo lokuqala lwenethiwekhi yemibhobho kamasipala.
Inkqubo yokubonelela ngamanzi oxinzelelo olungelulo olubi ibona utshintsho loxinzelelo lwenethiwekhi yombhobho wokuhambisa amanzi xa ukusetyenziswa kwamanzi kutshintsha nge-sensor yoxinzelelo oluphezulu okanye iswitshi yoxinzelelo efakwe kwinethiwekhi yombhobho wokuhambisa amanzi, kwaye iqhubeka nokudlulisela isignali etshintshileyo kwisixhobo esamkelayo. Ngokweemeko ezahlukeneyo zokusebenza, isixa sembuyekezo silawulwa ngokuguquguqukayo ukuze kufezekiswe ulungelelwaniso loxinzelelo oluguquguqukayo kwaye kuqinisekiswe uxinzelelo oluqhubekayo kwinethiwekhi yokubonelela ngamanzi ukuhlangabezana neemfuno zamanzi zomsebenzisi. Xa amanzi ompompo ohamba ngemibhobho kamasipala engena kwitanki elawulayo ngoxinzelelo oluthile, umoya osetankini yokuhlawula uxinzelelo uyakhutshwa kwi-vacuum eliminator, kwaye i-vacuum eliminator ivalwa ngokuzenzekelayo emva kokuba amanzi egcwele. Xa amanzi ompompo enokufikelela kwiimfuno zoxinzelelo lwamanzi kunye nomthamo wamanzi, izixhobo zokubonelela ngamanzi zibonelela ngokuthe ngqo ngamanzi kwinethiwekhi yombhobho wamanzi nge-valve yokujonga i-bypass; xa uxinzelelo lwenethiwekhi yombhobho wamanzi ompompo lungakwazi ukuhlangabezana neemfuno zamanzi, inkqubo iya kusebenzisa i-sensor yoxinzelelo, okanye iswitshi yoxinzelelo, kunye nesixhobo sokulawula uxinzelelo, sinike isignali yepompo ukuqala ukusebenza kwepompo yamanzi.
Ukongeza, xa amanzi enikezelwa yipompo, ukuba umthamo wamanzi kwinethiwekhi yamanzi empompini ungaphezulu kwesantya sokuhamba kwepompo, inkqubo igcina unikezelo lwamanzi oluqhelekileyo. Ngexesha lokusetyenziswa kwamanzi aphezulu, ukuba umthamo wamanzi kwinethiwekhi yamanzi empompini ungaphantsi kwesantya sokuhamba kwepompo, amanzi kwitanki elawulayo angasetyenziswa njengomthombo wamanzi owongezelelweyo wokubonelela ngamanzi ngokuqhelekileyo. Ngeli xesha, umoya ungena kwitanki elawulayo esuka kwi-vacuum eliminator, esusa uxinzelelo olubi lwenethiwekhi yamanzi empompini. Emva kwexesha lokuphakama kwamanzi aphezulu, inkqubo ibuyela kwimeko yayo eqhelekileyo. Ukuba unikezelo lwamanzi empompini alwanelanga okanye unikezelo lwamanzi kwinethiwekhi yepayipi luyekile, nto leyo ebangela ukuba inqanaba lamanzi kwitanki elawulayo lehle rhoqo, umlawuli wenqanaba lolwelo uya kunika isignali yokuvala ipompo yamanzi ukukhusela iyunithi yepompo yamanzi. Le nkqubo ijikeleza ngale ndlela, kwaye ekugqibeleni ifezekisa injongo yonikezelo lwamanzi ngaphandle koxinzelelo olubi.
