He kaupapa hangarau te keri e whakamahi ana i ngā taputapu me ngā hangarau keri hei whakawhanake me te whakamahi tika i ngā rauemi wai i roto i ngā paparanga o te whenua. Ko te wai whenua, i tētahi atu ringa, he wai kei roto i ngā kapiti o te kirinuku o te whenua, i ngā kapiti rānei o te oneone. Ko te wai i roto i ngā āhua rerekē kua tanumia ki raro i te mata o te whenua ka kiia ko te wai whenua.
Ko te pānga o ngā āhuatanga tapahi wai o ngā hanganga rerekē ki te hanga o ngā puna hinu e whai ake nei.
1. Ko ngā toka parataiao onepū me te kirikiri ma ngā mea pai rawa atu hei puna wai.
He nui te mimiti wai o tēnei hanganga, he nui te nui o te wai, ā, he pai hoki te uruhanga.
2. Paparanga whakaranu o te onepu me te kirikiri.
He hanganga whakaputa wai anō hoki te paparanga onepu me te kirikiri. He toka whakaputa wai tuarua tēnei nā te rerekētanga o te ōwehenga o te onepu. Ka iti ake te nui o te onepu, ka nui ake te wai e puta mai ana.
3. hanganga uku.
Ahakoa ka taea e ngā hanganga uku te pupuri i te wai, he uaua ki te wai te neke mā roto. Ko te tikanga tēnei kāore te hanganga uku e waipuke i te puna, nō reira ehara i te puna wai.
4. Kōhatu Oneone.
E pā ana tēnei ki te toka papatahi i whānau mai i te whenua, he 0.0625 ~2 mm te rahi o te kōhatu, ā, neke atu i te 50% o ngā matūriki papatahi katoa he onepu. He toka koretake te hanga wai mēnā ka mahi te uku i roto i te onepu hei sima hei pupuri i te onepu.
5. Kōhatu Tāwharau.
O ngā toka parataiao katoa, he puna wai pai tēnei. He nui ngā pūaha o te kōhatu pākeho, pērā i ngā ana karst i raro i te whenua, he nui te wai, engari he iti te kounga o te wai.
6. Pātarati.
He kikī ngā moenga tōmua, ehara i te pai te whakaputa wai nā te mea he piri tonu. Ki te tōmuri te wā, ka rite te tupu ki te hautai, ā, he puna wai pai.
7. He toka mārō.
Ko ngā toka pēnei i te karāneti, te pōpiri me ētahi atu toka tioata kāore i te tino pai te whakaputa wai. Ko ngā papa wai tino kino ko ngā toka metamorphic pēnei i te gneiss, te quartzite, te SLATE me te soapstone.
Hei karo i te koretake o te keri, me whiriwhiri ngā rahi o ngā mata kōne hinu paerewa i te wā e hoahoa ana i te diameter keri. Ko te whiriwhiri i te mata kōne paerewa mō te kōhao pairati me whakahaere te tukatuka o ngā mata kōne huihuinga reaming kia iti ake ai te utu o te tukatuka mata.
Ko te taumaha o te mata keri te awe o ngā tawhā keri ki te pai o te keri. Me whakatau te taumaha o te mata keri i runga i te pakeke me te ngawari o te hanganga. Me whai whakaaro hoki ki te kounga o te mata keri, te poka keri, ngā taputapu keri, te nekehanga me te mahi a te wai horoi, ngā taputapu me te mana.
Te whakamahinga tika o te mata toru: ngana ki te whiriwhiri i te momo mata toru e tika ana mō ngā whakaritenga o te whenua, whakatauritehia te rahi o te mata ki te hoahoa keri, ā, whakamahia kia rite ki te rahi. I te whakamahinga, ki te puta he ngangau, me tātari tonu te take kia tirohia mēnā ka rerekē te hanganga, ka hinga rānei te pakitara o te poka. Me tātari tonu, me whakatikatika hoki ngā tawhā. Ki te kore e taea e te mata hiki te keri i te tikanga, me tirotiro te mata hiki, ā, me tātari, me aromatawai hoki te āhua mahi o te mata i roto i te kōhao. Hei tāpiri, me mahi ngā mahi hei whakahaere i te rerekētanga o te tūranga o te poka, me whakaiti i te āputa i waenga i te taputapu keri me te kōhao, me te mahi hei keri kōhao-katoa me te ārai-rerekētanga pakari. Hei ārai i te rerekētanga, ka taea te tāpiri i tētahi mea whakawhāiti me tētahi kara keri ki te tihi o te mata toru.
