ʻO Iapana, ma kahi o ka ʻāina i hōʻailona ʻia e ka ʻepekema ʻokiʻoki, he ʻāina pū kekahi me nā koi kiʻekiʻe no ka maʻalahi ma ke ʻano o ke ola home. I ka lawe ʻana i ka māla wai inu i kēlā me kēia lā ma ke ʻano he laʻana, ua hoʻomaka ʻo Iapana e hoʻohanapaipu kila kilae like me nā paipu wai o ke kūlanakauhale ma 1982. I kēia lā, ʻoi aku ka kiʻekiʻe o ka nui o nā paipu wai kila kila i hoʻohana ʻia ma Tokyo, Iapana ma mua o 95%.
No ke aha i hoʻohana ai ʻo Iapana i nā paipu kila kila ma ke ʻano nui ma ke kahua o ka lawe ʻana i ka wai inu?
Ma mua o ka makahiki 1955, hoʻohana mau ʻia nā paipu galvanized i nā paipu hoʻolako wai ma Tokyo, Iapana. Mai ka makahiki 1955 a hiki i ka makahiki 1980, ua hoʻohana nui ʻia nā paipu plastik a me nā paipu kila-plastic composite. ʻOiai ua hoʻopau ʻia nā pilikia o ka maikaʻi o ka wai a me nā pilikia leakage o nā paipu galvanized, ʻoi aku ka koʻikoʻi o ka leakage ma ka pūnaewele hoʻolako wai o Tokyo, me ka piʻi ʻana o ka leakage i ka 40%-45% ʻae ʻole i nā makahiki 1970.
Ua hana ʻo Tokyo Water Supply Bureau i ka noiʻi hoʻokolohua nui e pili ana i nā pilikia leaka wai ma mua o 10 mau makahiki. Wahi a ka loiloi, ʻo 60.2% o nā leaka wai ke kumu no ka lawa ʻole o ka ikaika o nā mea paipu wai a me nā ikaika o waho, a ʻo ka 24.5% o nā kahe wai i kumu ʻia e ka hoʻolālā kūpono ʻole o nā hui paipu. ʻO 8.0% o ka leaka wai ma muli o ka hoʻolālā ala pipeline kūpono ʻole ma muli o ke kiʻekiʻe o ka hoʻonui nui ʻana o nā plastics.
No kēia hopena, paipai ka Japan Waterworks Association i ka hoʻomaikaʻi ʻana i nā mea paipu wai a me nā ʻano pili. E hoʻomaka ana mai Mei 1980, e hoʻohana nā paipu wai wai āpau me ke anawaena o lalo o 50 mm mai ka laina nui wai kōkua a hiki i ka mika wai e hoʻohana i nā paipu wai kila kila, nā hui paipu, nā kuʻekuʻe a me nā faucets.
Wahi a ka ʻikepili mai ke Keʻena Waiwai ʻo Tokyo, i ka piʻi ʻana o ka nui o ka hoʻohana ʻana i ke kila kila mai ka 11% i ka makahiki 1982 a i ʻoi aku ma mua o 90% i ka makahiki 2000, ua hāʻule pū ka nui o nā kahe wai mai ka 50,000 i kēlā me kēia makahiki i ka hopena o 1970s a i 2 -3 i ka makahiki 2000. , hoʻoponopono i ka pilikia o ka hoʻokahe ʻana i nā paipu wai inu no nā kamaʻāina.
I kēia lā ma Tokyo, Iapana, ua hoʻokomo ʻia nā paipu wai kila kila ma nā wahi noho a pau, kahi i hoʻomaikaʻi maikaʻi ai i ka maikaʻi o ka wai a hoʻonui i ka pale ʻana i ke olai. Mai ka hoʻohana ʻana i nā paipu wai kila kila ma Iapana, hiki iā mākou ke ʻike i nā mea maikaʻi o nā paipu wai kila kila ma ke ʻano o ka mālama ʻana i ke kaiapuni ʻōmaʻomaʻo, mālama waiwai, a me ke olakino a me ka maʻemaʻe.
I ko mākou ʻāina, ua hoʻohana mua ʻia nā paipu kila kila i ka ʻoihana koa. Ma hope o kahi kokoke i 30 mau makahiki o ka hoʻomohala ʻana, ua hoʻomaikaʻi nui ʻia ka ʻenehana huahana, a ua komo mālie i ke kahua o ka lawe ʻana i ka wai inu, a ua hoʻoikaika ikaika ʻia e ke aupuni. Ma Mei 15, 2017, ua hoʻopuka ke Kuhina o ka Hale a me nā Urban-Rural Development o Kina i ka "Direct Drinking Water Pipeline for Buildings and Residential Areas" System Technical Regulations", e ʻōlelo ana e hana ʻia nā paipu me nā paipu kila kila maikaʻi loa. Ma lalo o kēia ʻano, ua hānau ʻo Kina i kahi hui o nā ʻelele o nā ʻoihana aupuni a me nā ʻoihana pilikino me nā mana ʻenehana kiʻekiʻe.
