2.Ukukhethwa kwezinto zombhobho kufuneka kuhlangabezane nezi mfuno zilandelayo:
1) Imibhobho yamanzi ahlambulukileyo kunye nemibhobho yamanzi ahlambulukileyo kufuneka yenziwe ngemibhobho ye-polyvinyl chloride eqinile, iipayipi ze-polypropylene okanye iipayipi zensimbi ezingenasici;
2) Imibhobho yentsimbi enesitayile kufuneka isetyenziswe ukupholisa unikezelo lwamanzi olujikelezayo kunye nemibhobho yokubuyisela;
3) Iibhobho ezikumgangatho ophezulu kufuneka zisetyenziswe ukudityaniswa kwezixhobo zamanzi zokuvelisa kunye nemibhobho;
I-4) Izinto ezihambelanayo kufuneka zisetyenziswe kwizixhobo zombhobho.
3.Izixhobo zokubonelela ngamanzi abilayo zinokufakelwa kwindawo yokusebenzela ecocekileyo;isitya sokuhlamba kwindawo yokuhlambela kufuneka sinikeze amanzi atshisayo;amanzi athambileyo kunye nemibhobho yamanzi acocekileyo kufuneka alungelelaniswe kumazibuko okucoca agciniweyo, kwaye isixhobo sokucoca amanzi acocekileyo kufuneka sibekwe kufutshane nendawo yamanzi.
4.Izixhobo zokutshiza kufuneka zifakelwe kwindawo yokusebenzela ecocekileyo.
