Kāore e taea te whakanui rawa i te hiranga o ngā wāhanga pono mō te whakahaere i ngā pūnaha whakawhiti wai. Ko ngā rawhi piriti tētahi o ngā wāhanga matua e whakarite ana i te pumau me te whai huatanga o ēnei pūnaha. I hangaia mō ngā ngongo kōpikopiko, ka mau pūmau, ka whai hua hoki ngā rawhi piriti i te ngongo ki te hononga, hei ārai i ngā turuturu me te whakarite i te mahi tino pai.

He maha ngā ahumahi e paingia ana ngā ngongo kōpikopiko nā te mea he ngāwari, he māmā, he ātete hoki ki ngā pēhanga teitei. Heoi, nā te hoahoa motuhake i ētahi wā ka ngāwari te paheke o te ngongo mai i te hononga, ka momotu rānei. Koinei te wāhi e whai hua ai ngā rawhi piriti. Ka taea e ēnei rawhi te pupuri pūmau i te ngongo kia mau tonu ai te hononga ahakoa ngā piki me ngā heke o te pēhanga, te nekehanga rānei.

He ngāwari te tāuta i ngā rawhi piriti, ā, he mea rongonui ki ngā tohunga. Ka taea te whakarite kia ngāwari ki te whakauru i ngā diameter ngongo rerekē, ā, he pai mō ngā momo mahi mai i te motuka ki ngā taiao ahumahi. Hei tāpiri, ko ngā rawhi piriti he mea hanga ki ngā rauemi pakari pērā i te maitai kore waikura, i ngā kirihou kounga teitei rānei hei whakarite kia roa te ora me te ātete ki te waikura.

Mā te whakamahi i ngā rawhi piriti hei hono i ngā ngongo kōpikopiko, ehara i te mea ka whakaiti i te tūponotanga o ngā turuturu me te whakanui ake i te haumaru, engari ka whakapai ake hoki i te whai huatanga whānui o te pūnaha. Ko te tikanga o te hononga haumaru ka taea te rere pai o ngā wai me te kore e aukati, he mea nui tēnei mō ngā tukanga e whakawhirinaki ana ki te whakahaere wai tika.

I te katoa, ki te whakamahi koe i te ngongo kowakawaka, he mea nui te haumi ki tētahi rawhi piriti kounga teitei. Ka whakaratohia e rātou te tautoko e tika ana hei pupuri i tētahi hononga haumaru, kia pai ai te rere o tō pūnaha whakawhiti wai. Ahakoa kei roto koe i te hanga, i te motuka, i tētahi atu ahumahi rānei e whakamahi ana i te ngongo kowakawaka, he wāhanga iti engari kaha te rawhi piriti ka taea te hanga rerekētanga nui i roto i ō mahi.
