pūtēte pūwai
He tārai wai pūtahi he mea hēngi i whakamahia mo te hanga o ngā puwai i roto i ngā whenua rauemi rerekē. Ko tēnei āhua kōmihana e whakaaturia ana e te upoko kiriata me ngā niho rānei, e whai ake ana i te karbonga tūngarihi rānei ko ngā huinga diamond, i hangaia hei whakapiki ki roto i ngā one, ngā papa rānei me era atu raraunga whenua. Kia mahi te tārai i te whiringa i ngā haerenga nui, ahakoa te pānga ki raro, ka whakatetere te kawe puta me te whakakore i te raraunga kia hanga i te rua tārai. I ngā wā o nāianei, ko ngā tārai wai pūtahi e whai ake ana i ngā whakaaetanga mōhiohia, pērā i ngā wheiwheinga kiritaki matua, ngā ara whakakore kōriki whakapai, me ngā rārangi whakawaea wera hei tirotiro i te pai o te mahi. Ka tae ngā tārai nei ki ngā whatitanga rerekē, mai i ngā pou iti i runga i ngā pou rahi rawa, e hīkohia ana i ngā hiahia o te rua. Ko te hanga e whakaatu nei i te whakatakoto matua o ngā noela hei whakangungu i te wai tārai, ka whakamahia hei whakawaea i te tārai, hei whakahokia i te kiriata kiriata, me te kawe atu i ngā kāripi tārai. Ko te whiu anō o te tārai e pa ana ki ngā parae whakangungu me ngā raraunga whakamate i te wehe i ngā take whakarite, hei whakatika i te roa i ngā take hē. Ko tēnei kōmihana matua he mea nui rawa mo te hanga o ngā puwai wai, ngā taupori geothermal, me ngā kaupapa whakamomori whenua, ka kitea he mea kore tangata i te ao tārai.
