Mu bwubatsi bw'amazu, inyubako ya sima ahanini ikoresha uburyo bw'amazi buriho ubu. Nubwo ubu buryo bumaze igihe, bufite ingufu nyinshi zikoreshwa, umwanda mwinshi n'ikoranabuhanga rike. Mu "ubukungu bukoresha karubone nke", "inyubako zikomoka ku bidukikije" ibitekerezo bishya nko kuyobora, uburyo bwo kuvugurura ubwubatswe bw'amazu, guteza imbere inganda z'amazu, iterambere ry'amazu asanzwe yabaye inzira idashobora kwirindwa mu iterambere ry'amazu mu gihugu cyacu nk'uko ubunararibonye bugaragaza ko ugereranije n'uburyo busanzwe bwo kubaka sima isanzwe, inyubako zisanzwe zikoresha amazi 80%, zigabanye ibikoresho ku kigero kirenga 20%, zigabanya imyanda y'ubwubatsi ku kigero cya 80%, zigabanye ingufu ku kigero cya 70%, zigabanye ikiguzi cyo kubungabunga ku kigero cya 95%. Muri icyo gihe, aho kubaka hashobora kugabanuka kugira ngo hongerwe imikorere myiza y'ubutaka.
Ibisabwa mu mikorere ya kole yo gufunga inyubako yateguwe mbere
Gufatana ni kimwe mu bintu by'ingenzi ku ifunga. Ibi ni ko bimeze no ku bikoresho by'ibanze bikoreshwa mu nyubako zateguwe mbere. Muri iki gihe, inyinshi mu bikoresho bya PC bikoreshwa ku isoko bikozwe muri sima, bityo hari uburyo bwiza bwo gufatana kuri sima ku migozi. Ku bikoresho bya sima, gufatana kwa sema ku buso ntabwo byoroshye kugeraho, ibi biterwa nuko: (1) sima ni ubwoko bw'ibikoresho bifite imyenge, ingano y'umwobo idakwirakwira neza kandi ntishobora gufatana; Alkali (2) sima ubwayo, cyane cyane mu bikoresho by'ibanze, igice cy'ibintu bya alkali kizajya mu ifungana na sima, bityo bigira ingaruka ku gufatana; (3) Igice cya PC ku mpera y'igikorwa cyo gukora ipanga, kugira ngo ifungurwe izakoresha irekurwa ry'ibimera, kandi igice cy'ikintu gisohora kiguma ku buso bw'igice cya PC, nacyo gituma inkoni ya sema ihabwa imbogamizi.
