Nā te hanganga ahurei, pūwero, me te whānui o te mata o te waro whakahohe, me ngā kaha kukume, ka taea e te waro whakahohe te hopu me te pupuri i ngā momo rauemi ki runga i tōna mata. He maha ngā āhua me ngā momo o te waro whakahohe. Ka hangaia mā te tukatuka i tētahi rauemi waro, ko te nuinga he waro, he rakau, he kiri kokonati rānei, i roto i te taiao pāmahana teitei (pērā i te oumu hurihuri[5]) kia whakahohehia ai te waro me te hanga i te hanganga mata pūwero.
Ko te waro whakahohe tētahi o ngā hua e whakamahia nuitia ana i roto i te umanga maimoatanga wai. He tino pūwero tōna, he whānui hoki te mata, ā, he pai te mimiti. Nō roto te waro whakahohe i te rōpū rauemi waro pūwero he nui te kaha mimiti me te kaha whakaoho anō. He maha ngā matū e whakamahia ana hei rauemi turanga hei whakaputa AC. Ko ngā mea e whakamahia whānuitia ana i roto i te horoi wai ko te anga kokonati, te rakau, te waro anthracite me te peat.
He maha ngā momo waro whakahohe kei reira, he rerekē ngā āhuatanga o ia momo, e pai ai mō ngā mahi motuhake. Nō reira, he whānuitia ngā hua waro whakahohe e tukuna ana e ngā kaihanga. I runga i te whakamahinga, ka taea te whakamahi i te waro whakahohe i roto i te paura, te kirikiri, te whakaputa, tae noa ki te wai. Ka taea te whakamahi takitahi, te whakakotahi rānei me ngā hangarau rerekē, pēnei i te patu huakita UV. Ko te tikanga, ka whakamahia e ngā pūnaha maimoatanga wai he waro whakahohe kirikiri, he paura rānei, ko te waro whakahohe kirikiri (GAC) mai i te waro bituminous te momo e whakamahia whānuitia ana. Kua puta ake te anga kokonati hei tētahi o ngā momo waro whakahohe pai rawa atu mō ngā hiahia o te pūnaha tātari wai. He moroiti ngā waro whakahohe i hangaia i roto i te anga kokonati. He rite ēnei pore iti ki te rahi o ngā ngota poke i roto i te wai inu, nō reira he tino whai hua ki te hopu i a rātou. He rauemi whakahou ngā kokonati, ā, e wātea ana i te tau katoa. He nui te tipu, ā, ka taea te tiaki mō te wā roa.
Tērā pea kei roto i te wai ngā poke ka pā ki te hauora me te kounga o te oranga. Me kore he rauropi, he matū hoki e kino ana ki te hauora i roto i te wai e whakamahia ana e te tangata. Me kore he poke i te wai e inuhia ana e tātou i ia rā. E rua ngā momo wai inu: te wai parakore me te wai haumaru. He mea nui kia wehewehea ēnei momo wai inu e rua.
Ka taea te tautuhi i te wai parakore hei wai kāore he matū o waho, ahakoa he kino, he kore rānei. Heoi, mai i te tirohanga mahi, he uaua ki te whakaputa wai parakore, ahakoa ngā taputapu matatau o nāianei. I tētahi atu taha, ko te wai haumaru he wai kāore pea e pāngia e ngā pānga kino, ngā pānga kino rānei. Ahakoa kei roto i te wai haumaru ētahi poke, kāore ēnei poke e pāngia e ngā mōrearea, e ngā pānga kino rānei ki te hauora o te tangata. Me noho ngā poke ki roto i te awhe e whakaaetia ana.
Hei tauira, ka whakamahia te whakakōroira hei patu i te wai. Heoi, mā tēnei tukanga ka whakaurua ngā trihalomethanes (THM) ki roto i te hua kua oti. Tērā pea ka pāngia te hauora e ngā THM. E ai ki tētahi rangahau i whakaputaina i roto i te hautaka o te National Cancer Institute (St. Paul Dispatch & Pioneer Press, 1987), ko te inu wai whakakōroira te mea e piki ake ai te mōrearea o te mate pukupuku tōngāmimi tae atu ki te 80 ōrau.
I te piki haere o te taupori o te ao, me te piki haere o ngā hiahia mō te whakamahi i te wai haumaru, he mea nui te āwangawanga i ngā rā kei te heke mai kia pai ake te whai huatanga o ngā whare maimoatanga wai. I tētahi atu taha, kei te mōrearea tonu ngā tuku wai ki ngā whare e ngā poke pēnei i ngā matū me ngā moroiti.
Kua roa te waro whakahohe e whakamahia ana hei tātari wai mō te purenga o te wai inu. He whānuitia te whakamahinga mō te tango i ngā poke i roto i te wai nā te mea he nui tōna kaha ki te mimiti i aua matū, nā te nui o te mata me te porosity. He rerekē ngā āhuatanga o te mata me te rahi o ngā pore o ngā waro whakahohe, ā, he āhuatanga nui ēnei e whai wāhi ana ki te mimiti i ngā poke i roto i te wai.
