ʻO ke kūkulu ʻana o ka paipu i hoʻopili ʻia me ka hui pū ʻana e hōʻoiaʻiʻo ana he ikaika loa ia a kūpaʻa hoʻi i ke kaomi, e lilo ia i koho kūpono loa no nā ʻōnaehana wai ma lalo o ka honua.

Ma waho aʻe o ka ikaika a me ke kūpaʻa, ua hoʻolālā ʻia nā paipu wai ma lalo o ka honua no ka maʻalahi o ke kau ʻana. He maʻalahi a hiki ke hoʻololi ʻia ke kūkulu ʻana o ka wili wili, e ʻae ana i ka hoʻokele maʻalahi a me ke kau ʻana i ka ʻāina paʻakikī loa. ʻO ke ʻano kēia hiki iā ʻoe ke kau wikiwiki a me ka pono i nā paipu, e mālama ana i ka manawa a me nā kumukūʻai hana.

Eia kekahi, ʻo ka hoʻohana ʻana i nā mea hana kiʻekiʻe a me ka ʻenehana wiliwili holomua e hōʻoiaʻiʻo ana he kūpaʻa loa nā paipu wai ma lalo o ka honua i ka pala a me ka popo. ʻO ke ʻano kēia e mālama ia i kona kūpaʻa a me ka hana no nā makahiki, ʻoiai ma nā kūlana ʻino o ka honua.

Loaʻa kā mākou mau paipu wai ma lalo o ka honua i nā nui like ʻole e hoʻokō i nā pono kikoʻī o kāu papahana. Inā ʻoe e kau ana i kahi lako wai home liʻiliʻi a i ʻole kahi ʻōnaehana ʻoihana nui, loaʻa iā mākou ka paipu kūpono nou.

I ka wā e pili ana i nā ʻōnaehana wai ma lalo o ka honua, pono ʻoe i kahi paipu hiki iā ʻoe ke hilinaʻi. Me ke kūkulu ʻana i ka hui wili holomua, nā mea maikaʻi a me ka hoʻoheheʻe akamai, kūpono kā mākou mau paipu wai ma lalo o ka honua no kekahi pūnaewele lako wai.

Ma keʻano holoʻokoʻa, he koho maikaʻi loa nā paipu humuhumu wili no ka poʻe e pono ai kahi hopena hoʻolaha wai kiʻekiʻe, hilinaʻi, a paʻa hoʻi.
