Mea Hana VIGA Faucet 
Ma mua, Ua hoʻomohala ka ʻenekini Swiss ʻo ETFBastian Etter i kahi lua wai ʻole e hoʻokaʻawale ʻokoʻa i ka mimi. E hōʻiliʻili ia i ka lepo i hiki ke hoʻololi ʻia i mea hoʻomomona a hiki ke hoʻohana ʻia ka wai hoʻoheheʻe i mālama ʻia no ka irrigation.. Wahi a ka nupepa German, loaʻa ka mea hana me nā hopena wai ʻole.
Halepaku wai ʻole
Hoʻokaʻawale ʻia ka ʻōnaehana mālama lepo i ʻekolu mau pae: hoʻopaʻa ʻia ka nitrogen i loko o ka mimi e ka bacteria a wehe ʻia ka ʻala. Hoʻopili ia i nā koena lāʻau a me nā hormones ma ke ʻano mechanical. ʻO ka hope loa, ua hoʻopaʻa ʻia nā meaʻai e ka evaporation e hana i kahi mea momona ʻole.
Wahi a kēia ʻenekinia, aia ka nui o nā waiwai a me ka pono ʻole o ka hana ʻana o nā ʻōnaehana wai a me nā mea kanu lapaʻau. Hoʻopau ʻia ka nui o ka wai a me ka ikehu i ke kaʻina hana. Ua nalowale kekahi mau meaʻai i loko o ka lua wai ʻole.
No laila, ʻo kāna ʻike no ka ʻōnaehana hoʻoheheʻe e hiki mai ana e hana i kahi wai ʻole, ʻano decentralized, i.e. me ka pono ole o na hale hoolele wai nui.
No ka loaʻa ʻana o nā hopena wai ʻole, Ua mālama ʻo ia i ka manaʻo e hoʻokaʻawale i ka mimi a me nā feces. Akā ma kahi o ka holoi ʻana me ka wai, a kāʻei lawe lima hoʻohana ʻia e hoʻokuke i ka ʻili i loko o kahi pahu ʻokoʻa. Aia ka ʻōnaehana mālama i nā mea kanu a me nā hua bacteria, ʻoiai e hōʻiliʻili ʻia nā meaʻai.
E like me ke kahe ʻana o ka mimi i loko o kahi pahu ʻokoʻa, a laila kahe ia i loko o ka ʻōnaehana hoʻomaʻemaʻe ʻelua mika square i loaʻa i ʻelua ʻāpana. Lawe nā mea kanu a me nā hua bacteria i nā meaʻai mai ka wai, e hoʻoneʻe hou ʻia e ke kalapona hoʻāla e wehe i nā koena hormone a me nā koena lāʻau ma mua o ka hoʻohana ʻia ʻana o ka effluent no ka hoʻoinu ʻana.. Hoʻokomo ʻia ka ʻōpala i hoʻokaʻawale ʻia i loko o ka composter ilo no ka compost a hope e hana i ka lepo māla maikaʻi loa.
Ua hōʻike ʻia ua hoʻokomo ʻia ka ʻōnaehana ma nā wahi noho hou, no ka laʻana ma Geneva, a ma kekahi mau hale mauna.
