Uhlelo lomphakathi ludinga ukuhlinzeka ngendawo ezinzile nehlanzekile yokukhiqiza.Ngamanzi, igesi, umoya ocindezelweyo, igesi engasebenzi, njll., kufanele ihambisane nezidingo zokuhlanzeka zenqubo ehambisanayo yemithi, i-GMP kanye nemihlahlandlela nemithethonqubo ehambisanayo.Amanzi adingekayo ekukhiqizeni imboni yezemithi aphathwa ngokukhethekile.Ukuze uqinisekise ukuhlanzeka kwesakhiwo sefekthri noma akukho ukungcola ohlelweni lokuvutshelwa, igesi idinga ukuhlungwa.
Uhlelo lomphakathi oluzinzile lunikeza ukwesekwa okuqinile kokukhiqizwa okuqhubekayo kwamabhizinisi.Amanzi, igesi nomoya lapho kukhiqizwa zidinga ukuphathwa okukhethekile ukuze kuhlangatshezwane nezici zazo kanye nezidingo EZOKUSEBENZA Ukukhiqiza OKUHLE kanye nemihlahlandlela nemithethonqubo ehambisanayo.Amanzi enqubo yokukhiqiza: amanzi ahlanzekile, amanzi omjovo, amanzi okubulala inzalo omjovo, njll.
