Ko te 19 o Noema i ia tau ko te AoWharepakuTe Rā. Ka whakahaerehia e te International Toilete Organization ngā mahi i tēnei rā hei whakamōhio i te tangata kei te 2.05 piriona tāngata tonu o te ao kāore i te whai tiaki akuaku tika. Engari mō tātou e pai ana ki ngā wharepaku hou, kua mārama kē tātou ki te takenga mai o ngā wharepaku?
Kāore i te mōhiotia ko wai i hanga te wharepaku i te tuatahi. I kī ngā Kōtimana me ngā Kariki o mua ko rātou ngā kaihanga tuatahi, engari kāore he taunakitanga. I te tau 3000 BC i te wā Neolithic, i noho tētahi tangata ko Skara Brae te ingoa i te whenua nui o Kōtimana. I hanga e ia tētahi whare ki ngā kōhatu, ā, i whakatuwherahia he kauhanga e toro atu ana ki te kokonga o te whare. E whakapono ana ngā kaituhi hītori ko tēnei hoahoa te tohu o ngā tāngata o mua. Te tīmatanga o te whakaoti rapanga wharepaku. I te tau 1700 BC pea, i te Whare Ariki o Knossos i Crete, ka mārama ake te mahi me te hoahoa o te wharepaku. I honoa ngā paipa oneone ki te pūnaha tuku wai. I rere te wai mā roto i ngā paipa uku, ka taea te horoi i te wharepaku. Te tūranga o te wai.
I te tau 1880, ka utua e te Piriniha Edward o Ingarangi (nō muri mai ko Kingi Edward VII) a Thomas Crapper, he kaimahi paipa rongonui o taua wā, ki te hanga wharepaku i roto i ngā whare kingi maha. Ahakoa e kīia ana nā Crapper i hanga he maha ngā mea hou e pā ana ki ngā wharepaku, ehara a Crapper i te kaihanga o te wharepaku hou e ai ki te whakaaro o te katoa. Ko ia anake te tuatahi ki te whakaatu i tana mea hou mō te wharepaku ki te marea i roto i te ahua o tētahi whare whakaaturanga, kia mahara tonu ai te marea ki a ia mēnā he wharepaku e hiahiatia ana, he taputapu rānei e hiahiatia ana.
Ko te wā i tino rongonui ai ngā wharepaku hangarau i te rautau 20: ngā takirere horoi, ngā tāke wai, me ngā rōra pepa wharepaku (i hangaia i te tau 1890, ā, i whakamahia whānuitia tae noa ki te tau 1902). Ahakoa te iti o ēnei mea hou, kua waiho hei taonga nui ināianei. Ki te whakaaro tonu koewharepaku houkāore i tino rerekē, me titiro tātou: I te tau 1994, i paahitia e te Paremata o Peretānia te Ture Kaupapahere Pūngao, e hiahia ana kia whakamahia ngā tikanga noawharepaku horoikia 1.6 karani wai anake te wai e horoia ana i te wā kotahi, ko te haurua o te mea i whakamahia i mua. I whakahēngia te kaupapa here e te iwi nā te mea he maha ngā wharepaku i purua, engari i tere tonu te hanga e ngā kamupene horoi he pūnaha wharepaku pai ake. Ko ēnei ngā pūnaha e whakamahia ana e koe i ia rā, e mōhiotia ana ko ngā pūnaha hou.wharepakungā pūnaha.
