The Evolution of Sanitation Marara Marari: Kubva Mhuka-Yadhonzwa kusvika Yakazara Magetsi-1

Marori anorasira marara imotokari dzinokosha pakutakura marara mumaguta. Kubva pangoro dzemarara dzakadhonzwa nemhuka kusvika kumarori emarara akazara emagetsi, akangwara, uye anofambiswa neruzivo, chii chave chiri chirongwa chekusimudzira?

Mabviro emarori emarara akatanga kuEurope kuma1920 nema1930. Marori ekutanga emarara aisanganisira ngoro inodhonzwa nebhiza ine bhokisi, ichitsamira chose pasimba remunhu neremhuka.

Mumakore ekuma1920 Europe, nekutorwa kwakapararira kwemotokari, marori emarara echinyakare akatsiviwa zvishoma nezvishoma nemarori emarara akavhurika pamusoro. Zvisinei, dhizaini yakazaruka yakabvumira kunhuhwirira kwakashata kubva mumarara kuti kupararire nyore nyore munzvimbo yakapoteredza, yakakundikana kudzora zvinobudirira guruva, uye kukwezva zvipembenene zvakadai semakonzo neumhutu.

Nekuwedzera kuziva kwezvakatipoteredza uye kufambira mberi kwetekinoroji, Europe yakaona kukwira kwemarori emarara akavharwa, ayo aive nemudziyo usingapindi mvura uye nzira yekusimudza. Zvisinei nekuvandudzwa uku, kutakura marara kwakanga kuchiri kushanda nesimba, zvaida kuti vanhu vasimudze mabhini kusvika paurefu hwemapfudzi.

Gare gare, maGermany akagadzira pfungwa itsva yemotokari dzinotakura marara. Marori aya aisanganisira spiral mudziyo wakafanana nemuvhenganisi wesimende. Muchina uyu waibvumira kuti zvinhu zvihombe, sematerevhizheni kana fenicha, kupwanywa uye kunaniswa pamberi pemudziyo.

Kutevera izvi kwaive kwerori remarara rekumashure rakagadzirwa muna 1938, iro rakabatanidza zvakanakira marori emarara ekunze ane hydraulic cylinders kuti atyaire tireyi yemarara. Iyi dhizaini yakawedzera zvakanyanya kugona kwekubatanidza kwerori, ichiwedzera kugona kwayo.

Panguva iyoyo, imwe dhizaini yakakurumbira yaive rori rekutakura marara parutivi. Yaiva nechikamu chakasimba chekuunganidza marara, umo marara airasirwa paburi padivi pegaba. A hydraulic cylinder kana compression plate yakabva yasaidzira marara kuseri kwegaba. Zvisinei, rori yorudzi urwu yakanga isina kukodzera kubata zvinhu zvikuru.

Pakati pemakore ekuma1950, Dumpster Truck Company yakagadzira rori rekutakura marara mberi, iro rakanga rakanyanya kufambira mberi panguva yayo. Yaiva nechanza chemechanic chinogona kusimudza kana kudzikisa chigadziko, zvichideredza zvakanyanya basa remaoko.
