I-Polymer concrete sump yimingxuma egqunywe ngeebhloko ngamaxesha athile xa kugqunywa imibhobho engaphantsi komhlaba okanye xa ijikajika. Ilungele ukuhlolwa kwemibhobho eqhelekileyo kunye nokuchithwa. Ukuqokelelwa kwekhonkrithi yeresin kakuhle yinxalenye ebalulekileyo yenkqubo yokuhambisa amanzi. Ayenzi nje kuphela ukuchithwa kwenkqubo yokukhupha amanzi, ukuqokelela inkunkuma, kunye nokukhusela ukusebenza okuqhelekileyo kwesistim sombhobho, kodwa ingasetyenziselwa njengomthombo wokuhlola ukudlala indima ebalulekileyo ekugcinweni kwenkqubo yokuhambisa amanzi. Ukuqokelelwa kwamanzi okugqityiweyo kakuhle kuneempawu zobukhulu obuchanekileyo, ubunzima obulula kunye namandla aphezulu, okunciphisa kakhulu ixesha lokufakela kwaye liyinxalenye ebalulekileyo yenkqubo yokuhambisa amanzi ekwakhiweni kweprojekthi.
