Inkqubo yoluntu kufuneka ibonelele ngemeko-bume ezinzileyo necocekileyo yokuvelisa.Kumanzi, igesi, umoya oxinzelelweyo, igesi ye-inert, njl., kufuneka ihambelane neemfuno zokucoceka kwenkqubo ehambelanayo yamachiza, i-GMP kunye nezikhokelo kunye nemimiselo ehambelanayo.Amanzi afunekayo kwimveliso yeshishini lamachiza aphathwa ngokukodwa.Ukuqinisekisa ukucoceka kwesakhiwo somzi-mveliso okanye akukho ngcoliseko kwinkqubo yokuvutshelwa, irhasi kufuneka icocwe.
Inkqubo yoluntu ezinzileyo ibonelela ngenkxaso eyomeleleyo kwimveliso eqhubekayo yamashishini.Amanzi, igesi kunye neenkqubo zomoya kwimveliso zifuna unyango olukhethekileyo ukuhlangabezana neempawu zabo kunye neemfuno zokuvelisa OKULUNGILEYO kunye nezikhokelo kunye nemimiselo ehambelanayo.Amanzi enkqubo yokuvelisa: amanzi ahlambulukileyo, amanzi okutofa, amanzi okucoca inzala, njl.
