I-GL ihlinzeke ngamaketanga abalulekile okuhlanzwa kwamanzi emishini ehlukahlukene yokuhlanza amanzi, engasetshenziswa emgqeni wokukhiqiza wezinto zokuhlanza amanzi okuhlanganisa ukuhlanzwa kwamanzi okuthutha, ibhokisi lenhlabathi yokusanhlamvu okusanhlamvu, ukuthungwa kwenhlabathi kokuqala kanye nenhlabathi yesibili. Ukuze kuhlangatshezwane nezidingo zokusebenza zemishini ehlukene yokuhlanza amanzi, i-GL ayikwazi kuphela ukuhlinzeka ngamaketanga okuhlanza amanzi enziwe ngensimbi engagqwali kanye nensimbi ekhethekile ye-alloy, kodwa futhi inikeze ngamaketanga okwelapha amanzi abunjiwe.Impahla ingaba uchungechunge lwe-300,400,600 yensimbi engagqwali.
