KETI PENSTOCK
He pai te reo mahi mō te wai, tata ki te kore e turuturu,
ā, koinei te otinga pai rawa atu mō ngā whare tukatuka matū me te paru.
I roto i ngā hanganga wai hou, inā koa i roto i ngā pūnaha tāpua me ngā puna wai, ko te keti waipara pakitara he tikanga nui mō te whakahaere pai o te wai. Ko tēnei hanganga motuhake, e kiia ana ko ngā takirere taiepa, ko te takirere taiepa rānei, he mea hanga hei whakahaere i te tukunga wai mā roto i tētahi keti reti poutū, whakapae rānei kua whakauruhia ki roto i ngā hanganga raima, kohatu rānei. Ko ngā momo mahi mai i ngā pūnaha keti ringa—he pai mō ngā tono rere iti e hiahia ana ki te whakahaere tika a te tangata—ki ngā whakatakotoranga aunoa matatau, e taea ai te whakarerekē tika i ngā taumata wai me ngā tere rere kia tutuki ai ngā hiahia whakahaere.
Hei tūāpapa mō te hangarau waipēhi, ko te keti waipara pakitara he tauira o te whakakotahitanga o te tika, te pakari, me te urutau. Ahakoa he keti waipara ā-ringa mō te whakamakuku iti, he takirere waipara pakitara aunoa rānei i roto i ngā tāhuna wai nui, kāore he rite o tana mahi ki te whakataurite i te tuku wai, te aukati i ngā waipuke, me te whakarei ake i te haumaru hanganga.
