Nyamara, abahanga n'abashakashatsi barimo gukora kuburyo butandukanye bwo kubyara amazi meza kuva muri sisitemu ntoya kugeza mubucuruzi ninganda.Sisitemu ikoreshwa cyane muri ubu, ni centre de desalisale na sisitemu ya membrane.Sisitemu yubushyuhe ikoresha ubushyuhe.Nubwo sisitemu yo gutekesha ihenze cyane kandi isaba ingufu nyinshi zihenze, ubu buryo bwahinduye isi muburyo bwo kubyara amazi meza.Sisitemu ya Membrane, ntisaba uburyo bwinshi bugoye.Ukoresheje igitutu nubwoko bwihariye bwa membrane hamwe nurupapuro rwemerera gusa amazi meza kunyuramo.Ubu buryo, amazi meza atangwa vuba vuba.
Imijyi kwisi yose ifite ikibazo cyumutekano muke.Imihindagurikire y’ibihe itera ubushyuhe bwiyongereye hamwe nigihe cyigihe cyizuba.Ibisabwa muri ibi bihe biriyongera, ariko imvura itinze cyangwa itabaho ibihe by'imvura bigabanya itangwa, bityo bigashyira imbaraga nyinshi kubutunzi.Uku kubura amazi meza mumijyi bishyira mukaga ko kugera kumunsi wa Zeru.Umunsi Zero ni igihe cyagereranijwe aho umujyi cyangwa akarere bidashobora guha ubushobozi bwo guturamo amazi meza.Inzira ya hydrologique ifitanye isano rya bugufi nihinduka ryubushyuhe bwikirere hamwe nuburinganire bwimirasire, bivuze ko ikirere gishyushye gitera umuvuduko mwinshi hamwe nubushyuhe bwimvura.
At HISHA, twishimiye kuba imwe mu masosiyete akomeye akora ibijyanye no kurwanya umunsi wa Zeru mu turere twinshi ku isi dushobora guhura n'ikibazo cyo kubura amazi.Itsinda ryacu ryubushakashatsi rikora kubyara umusaruro mwiza usaba imbaraga nke zo gusarura amazi meza yo kunywa.Turashishikariza isi kubungabunga cyane umutungo w'agaciro no gufatanya no kurwanya Day Zero kwisi yose.
