Haunga te mea he whenua rongonui a Hapani mō te pūtaiao matatau, he whenua anō hoki e hiahiatia ana te mātauranga matatau i roto i te ao o te noho kāinga. Hei tauira, ka tīmata a Hapani ki te whakamahi i te wai inu o ia rā.ngā paipa kowiri tirahei paipa wai mō ngā tāone i te tau 1982. I ēnei rā, ko te ōwehenga o ngā paipa wai kowiri tira e whakamahia ana i Tōkyō, Hapani e neke atu ana i te 95%.
He aha i whakamahia nuitia ai e Hapani ngā paipa kowiri tira i roto i te ao kawe wai inu?
I mua i te tau 1955, i whakamahia whānuitia ngā paipa piauau i roto i ngā paipa tuku wai puna i Tōkyō, Hapani. Mai i te tau 1955 ki te tau 1980, i whakamahia whānuitia ngā paipa kirihou me ngā paipa hiato maitai-kirihou. Ahakoa kua ea te kounga o te wai me ngā raruraru turuturu o ngā paipa piauau, he tino kino tonu te turuturu i roto i te whatunga tuku wai o Tōkyō, ā, i te tekau tau atu i 1970, kua eke te auau turuturu ki te 40%-45% kāore e taea te whakaae.
Neke atu i te 10 tau te roa o te rangahau whakamātautau a te Tari Tuku Wai o Tōkyō mō ngā raruraru turuturu wai. E ai ki ngā tātaritanga, 60.2% o ngā turuturu wai nā te koretake o te kaha o ngā rauemi paipa wai me ngā kaha o waho, ā, 24.5% o ngā turuturu wai nā te hoahoa koretake o ngā hononga paipa. 8.0% o ngā turuturu wai nā te hoahoa koretake o ngā ara paipa nā te tere whānui o ngā kirihou.
Hei whakatutuki i tēnei, e taunaki ana te Japan Waterworks Association kia whakapai ake i ngā rauemi me ngā tikanga hononga o ngā paipa wai. Mai i te marama o Mei 1980, ko ngā paipa wai katoa he iti iho i te 50 mm te whānui mai i te raina matua wai āwhina ki te mita wai ka whakamahia he paipa wai kowiri tira, he hononga paipa, he tuke me he taputapu wai.
E ai ki ngā tatauranga mai i te Tari Tuku Wai o Tōkyō, i te pikinga ake o te whakamahinga o te maitai kore waikura mai i te 11% i te tau 1982 ki te neke atu i te 90% i te tau 2000, ka heke te maha o ngā turuturu wai mai i te neke atu i te 50,000 ia tau i te mutunga o te tekau tau atu i 1970 ki te 2-3 i te tau 2000. , i whakatau i te raru o te turuturu o ngā paipa wai inu mō ngā kainoho.
I Tōkyō, Hapani, kua tāutahia ngā paipa wai kowiri tira ki ngā wāhi noho katoa, ā, kua tino pai ake te kounga o te wai, kua ātete hoki ki te rū whenua. Mai i te whakamahinga o ngā paipa wai kowiri tira ki Hapani, ka kitea e tātou he kore e taea te whakahē i ngā painga o ngā paipa wai kowiri tira e pā ana ki te tiaki taiao matomato, te tiaki rauemi, me te hauora me te akuaku.
I tō tātou whenua, i te tīmatanga, ko ngā paipa kowiri tira te mea nui i whakamahia i roto i te umanga hōia. I muri i te tata ki te 30 tau o te whanaketanga, kua tino pai ake te hangarau hua, ā, kua uru mārire ki te ao o te kawe wai inu, ā, kua kaha te whakatairanga a te kāwanatanga. I te 15 o Mei, 2017, i whakaputa te Manatū Whare me te Whanaketanga Tāone-Taiwhenua o Haina i te "Whakahaerenga Hangarau Pūnaha Paipa Wai Inu Tika mō ngā Whare me ngā Wāhi Noho", e whakatau ana me hanga ngā paipa ki ngā paipa kowiri tira kounga teitei. I raro i tēnei āhua, kua whānau mai i Haina he rōpū māngai o ngā umanga kāwanatanga me ngā umanga tūmataiti he kaha hangarau teitei.
