Ukuvalwa kwevalve yamanzi kusetyenziswa ikakhulu ukutshixa isivalo samanzi nokukhusela ukhuseleko lwevalvu.Nokuba isixhobo sokuvala isivalo samanzi siyasetyenziswa okanye asisetyenziswa sinxulumene nokubaluleka kokusebenza ngokukhuselekileyo;Ezinye iivalve zihlala zivulekile, ezinye iivalve zihlala zivaliwe, ezifuna ukuqwalaselwa kokhuseleko, ukuze kuthintelwe ukungasebenzi kakuhle, ngoko ke uyilo lokuvalwa kwevalve yamanzi, injongo kukuqinisekisa ukuba ukusetyenziswa kwesixhobo sevalve kuvalwe ngokupheleleyo, izixhobo. igcinwe kwindawo ekhuselekileyo;Ukuvalwa kwevalve yamanzi kunokuthintela ukusetyenziswa ngengozi kwesixhobo, okukhokelela kukwenzakala okanye ukufa, kodwa kukwasebenza njengesilumkiso.

Usetyenziso lwesixhobo sokutshixa isivalo samanzi

• 1. Iivalvu zemibhobho ezisetyenziswa kwiinkqubo zepetroleum, iikhemikhali nezamashishini;
• 2. Izivalo zemibhobho yogcino lwamanzi, amandla ombane, umasipala kunye nezinye iinkqubo zemibhobho karhulumente;
• 3. Iivalvu zepayipi ezifanelekileyo kwiinkqubo ezinkulu zemibhobho ezifana nekhemesti, ukwenza iphepha, intsimbi kunye nesiselo;
• 4. Ivalve yombhobho ilungele inkqubo yemibhobho yoshishino lolwakhiwo, isithili sorhwebo, indawo yokuhlala usapho, njl.;
• 5. Isebenza kuzo zonke ezinye iinkqubo zemibhobho ezineevalvu zokukhusela ukhuseleko.
