Menya igihe kiza cyo kuhira

Amazi ningenzi cyane ku bihingwa no kubidukikije ariko kuyakoresha nabi igihe kidakwiye, kutayacunga ibyo byatuma dututakaza umusaruro ariko ibyo byose iyo bikozwe neza,  umusaruro mwiza uraboneka kandi ufite agaciro ku isoko. Kuhira si ugushyira amazi gusa mu murima, ni ugutanga amazi ku gihingwa mu gihe gikwiye, ku kigero gikwiye, kandi hashingiwe ku byo igihingwa n’ubutaka bikeneye.
