Mugihe uhisemo uruganda rwa ERW ruzunguruka, ibintu ugomba gusuzuma birimo ubushobozi bwo gukora, urwego rwa diameter ya pipe, guhuza ibikoresho, urwego rwikora, hamwe ninkunga yo kugurisha. Ubwa mbere, ubushobozi bwo kubyaza umusaruro nikintu cyingenzi kigena umubare w'inganda zingana zishobora gutanga mugihe cyagenwe. Guhitamo uruganda ruzunguruka rufite ubushobozi bwo kubyaza umusaruro ibyo ukeneye bitagutse cyane ni ngombwa kugirango umusaruro ukorwe neza no kugenzura ibiciro muburyo bwemewe.
