Ko te whakatau ki te tango wai i roto i te whare horoi waka e ahu mai ana i ngā take ōhanga, taiao, ture rānei. E whakatakoto ana te Ture Wai Ma i ngā ture kia hopukina e ngā whare horoi waka ā rātou wai para, ā, kia whakahaeretia hoki te whakakorenga o ēnei para.
I tua atu, kua aukatia e te Tari Tiaki Taiao o Amerika te hanganga o ngā waikeri hou e hono ana ki ngā puna para waka. Kia whakamanahia tēnei aukati, ka nui ake ngā whare horoi waka e hiahia ana ki te tirotiro i ngā pūnaha whakahoki para.
Ko ētahi matū e kitea ana i roto i te awa para o ngā wāhi horoi waka ko: te benzene, e whakamahia ana i roto i te penehīni me ngā hopi horoi, me te trichloroethylene, e whakamahia ana i roto i ētahi tango hinu me ētahi atu matū.
Ko te nuinga o ngā pūnaha whakahoki mai he huinga o ēnei tikanga: ngā tāke taunga, te waikura, te tātari, te whakapūpū me te ozone.
Ko ngā pūnaha horoi waka ka whakarato i te wai kounga teitei i waenga i te 30 ki te 125 karani ia meneti (gpm) me te whakatauranga matūriki o te 5 maikorona.
Ka taea te whakatutuki i ngā whakaritenga rere karani i roto i tētahi whare noa mā te whakamahi i te huinga o ngā taputapu. Hei tauira, ka taea te whakahaere i te haunga me te tango tae o te wai kua whakahokia mai mā te maimoatanga ozone kukū-teitei o te wai e puritia ana i roto i ngā tāke pupuri, i ngā poka rānei.
I te wā e hoahoa ana, e tāuta ana, e whakahaere ana hoki i ngā pūnaha whakahoki wai mō ngā wāhi horoi waka a ō kiritaki, me whakatau tuatahi ngā mea e rua: mēnā he pūnaha tuwhera, he pūnaha kati rānei hei whakamahi, me te mea hoki he huarahi ki te waikeri.
Ka taea te whakahaere i ngā tono noa i roto i te taiao porowhita kati mā te whai i tētahi ture whānui: Ko te nui o te wai māori e tāpirihia ana ki te pūnaha horoi kaua e neke ake i te ngaronga o te wai e kitea ana i te mimiti, i ētahi atu tikanga rānei o te kawe atu.
Ka rerekē te nui o te wai e ngaro ana i runga i ngā momo horoinga waka rerekē. Ko te tāpiri i te wai māori hei utu mō te ngaronga o te wai e tangohia ana me te mimiti ka mahia tonutia hei horoinga whakamutunga o te horoinga. Ka tāpirihia e te horoinga whakamutunga te wai i ngaro. Me whakamahi tonu te horoinga whakamutunga i te pēhanga teitei me te iti o te rahinga hei horoi i ngā toenga wai i whakamahia i roto i te tukanga horoi.
Mēnā he wāhi horoi waka motuhake e wātea ana mō te wai para, ka taea e ngā taputapu maimoatanga wai te tuku i te ngāwari ake ki ngā kaiwhakahaere horoi waka i te wā e whiriwhiri ana i ngā mahi e whakamahi ana i te wai whakahoki, i te wai māori rānei i roto i te tukanga horoi. Tērā pea ka whakawhirinaki te whakatau ki te utu o ngā utu whakamahi wai para me ngā utu e pā ana ki te kaha o te puna wai para, te wai para rānei.
