Izinkinga ezinamapayipi Ensimbi Ejwayelekile (Angewona awe-SML) eDrainage Yokwakha: Isidingo Sokulungiswa

Nakuba amapayipi ensimbi kulindeleke ukuthi abe nokuphila okufika eminyakeni eyi-100, lawo asezindlini eziyizigidi ezifundeni ezifana ne-Southern Florida ahlulekile esikhathini esingaphansi kweminyaka engama-25. Izizathu zalokhu kucekelwa phansi okusheshayo izimo zezulu kanye nezici zemvelo. Ukulungisa la mapayipi kungase kubize kakhulu, ngezinye izikhathi kufinyelele amashumi ezinkulungwane zamaRandi, kanti ezinye izinkampani zomshwalense zenqaba ukukhokhela izindleko, okushiya abaninikhaya abaningi bengakulungele ukubhekana nezindleko.

Kungani amapayipi ehluleka ngokushesha okungaka ezindlini ezakhiwe eSouthern Florida uma kuqhathaniswa nezinye izifunda? Isici esibalulekile ukuthi la mapayipi awamboziwe futhi anengaphakathi elimahhadlahhadla, okuholela ekunqwabeleni kwezinto ezinomucu njengephepha lasendlini yangasese, okubangela ukuvaleka ngokuhamba kwesikhathi. Ngaphezu kwalokho, ukusetshenziswa njalo kwezihlanzi zamakhemikhali ezinokhahlo kungasheshisa ukugqwala kwamapayipi ensimbi. Ukwengeza, ukugqwala kwamanzi nenhlabathi yaseFlorida kunomthelela ekungasebenzini kwamapayipi. Njengoba osebenza ngamapayipi uJack Ragan ephawula, “Lapho amagesi endle namanzi kugqwala kusukela ngaphakathi, ingaphandle nalo liqala ukugqwala,” okudala “umsindo ophindwe kabili” oholela ekugelezeni ukungcola ezindaweni lapho kungafanele khona.

Ngokuphambene, amapayipi okudonsa amanzi ensimbi e-SML ahlangabezana nezindinganiso ze-EN877 anikeza ukuvikeleka okuthuthukisiwe kulezi zinkinga. Lawa mapayipi anemihlobiso ye-epoxy resin ezindongeni zangaphakathi, enikeza indawo ebushelelezi evimbela ukukala nokugqwala. Udonga lwangaphandle luphathwa ngopende ophikisana nokugqwala, okuqinisekisa ukumelana kangcono nomswakama wemvelo kanye nezimo ezigqwalayo. Le nhlanganisela yezingubo zangaphakathi nezangaphandle inika amapayipi e-SML isikhathi eside sokuphila kanye nokusebenza okuthembeke kakhudlwana ezimeni eziyinselele, okuwenza abe yisixazululo esihlala isikhathi eside futhi esingabizi kakhulu sokwakha izinhlelo zokudonsa amanzi.
