Zininzi iintlobo zokupholisa kwizikhululo ezinkulu zamanzi, kubandakanya ukupholisa amanzi kunye nokupholisa umoya.
Ukupholisa amanzi kunokwahlulwa kube kubanda beetyhubhu kunye nokupholisa iipleyiti ngokwamalungu ahlukeneyo.
Umgaqo osebenzayo wokupholisa amanzi kukuvumela indawo yokufudumeza kunye nendawo ebandayo yokuhambisa kunye nokutshintsha ubushushu, ukuze kufezekiswe injongo yokupholisa.
Ukhetho luxhomekeke kumandla otshintshiselwano ngobushushu ukumisela indawo yokupholisa.
1. Iimfuno zomsebenzi
(1) Kufuneka kubekho indawo eyaneleyo yokusasaza ubushushu ukugcina iqondo lobushushu leoyile likuluhlu oluvumelekileyo.
(2) Ukuphulukana noxinzelelo kufanele kube kuncinci xa ioyile idlula.
(3) Xa inkqubo itshintsha ukutshintsha, kulula ukulawula ioyile ukugcina iqondo lobushushu elingagungqiyo.
(4) Banokomelela ngokwaneleyo.
2. Iindidi (ezihlelwe ngokweendaba ezahlukeneyo)
(1) Amanzi apholileyo apholileyo (inyoka ityhubhu epholileyo, ityhubhu epholileyo kunye nepleyiti ebandayo)
(2) umoya opholileyo opholileyo
(3) Ukuphola okupholileyo kweMedia (ukwahlula umoya opholileyo)
3.Ukufakwa: Okupholileyo kufakwa ngokubanzi kumbhobho wokubuyisela ioyile okanye kumbhobho ophantsi woxinzelelo, kwaye unokufakwa kwindawo yeoyile yempompo ye-hydraulic xa kufanelekile ukwenza isekethe yokupholisa ezimeleyo
