Nga Painga o nga Waa Purerehua:
1. He watea, he tere hoki te whakatuwheratanga me te kati o te puera rerehua, he whakaora mahi, he iti te parenga wai, na reira ka taea te whakahaere i nga wa katoa.
2. He maamaa te hangahanga o te rewharewha, he iti te rahi, he poto te roa o te hanganga, he iti te rahi me te marama o te taumaha, he pai hoki mo nga waahanga nui-diameter.
3. Ka taea e te rewharewha te kawe paru, a ko te wai e kohia ana ki te waha o te putorino he iti rawa.
4. Ka taea e te rewharewha te whakatutuki i te hiri pai i raro i te pehanga iti.
5. He pai te mahi whakahaere o te rewharewha.
6. Ka tino tuwhera, ka nui ake te waahi rere whai hua o te hongere nohoanga takirere, ka iti ake te parenga wai.
7. He iti te taipana whakatuwhera me te kati, no te mea he rite tonu nga papa pererererere i nga taha e rua o te kaa hurihuri ki te mahi a te reo, a he rereke te ahunga o te taipana, no reira he mahi te whakatuwhera me te kati- whakaora.
8. Ko nga mea o te mata hiri o te puera rerehua he mea hanga ki te rapa, ki te kirihou ranei, no reira he pai te mahi hiri pehanga iti.
9. He ngawari te whakauru o te puera rererere.
10. He ngawari te mahi me te whakaora i nga mahi, ka taea te whiriwhiri i nga tikanga a-ringa, hiko, pneumatic me te hydraulic.
