Akunakuphepheka ukuqwalasela ukuba umsele wokuhambisa amanzi obekwe ngaphandle unokuthwala ngokukhuselekileyo umhambi ngeenyawo okanye umthwalo wesithuthi obekwe kuwo.
Ngokubhekiselele kumthwalo, sinokuwuhlula ube ngamacandelo amabini: umthwalo omileyo kunye nomthwalo oguqukayo.
● umthwalo omileyo
Amandla omthwalo asebenza ngokuthe nkqo kwisixokelelwano somsele wokuhambisa amanzi ngaphandle kweminye intshukumo.Ngokuqhelekileyo isetyenziselwa ukuvavanya umthamo wokuthwala isitya sokugubungela kunye nomzimba womsele.Kwisicelo esisebenzayo, kuphela abantu okanye ezinye iimveliso ezibekwe emseleni.
● umthwalo oguqukayo
Isithuthi esihambayo sivelisa umthwalo oguqukayo, onokuvelisa i-torque ukukhupha umsele.Umthwalo othwelwe ngumzimba womsele kunye nepleyiti yokuvala, indlela yokwakha kunye nenkqubo yokutshixa zizinto ezifuna ukuhoywa xa kuqwalaselwa umthwalo oguqukayo.
Ukuthwala umgangatho we-EN1433
Ukwahlula ibakala lokuthwala umthwalo luncedo ekukhetheni iimveliso ezifanelekileyo ngokwemeko yangempela yeprojekthi, ukwenzela ukuba inkqubo yokuhambisa i-linear drainage ikwazi ukufezekisa ubomi obude benkonzo ngaphandle kokuchitha iindleko zebhajethi.Okwangoku, zonke iimveliso zasekhaya kunye nezangaphandle zihlulwe zibe ngamabakala amathandathu athwala umthwalo wesicelo: A15, B125, C250, D400, E600 kunye ne-f900 ngokwe-European Union EN1433 umgangatho kunye nommandla wezithuthi zangaphandle.
Indawo yabahambi ngeenyawo, ibhayisekile kunye nezinye iindawo zokuqhuba isithuthi esilula, njengesitalato sabahambi ngeenyawo kunye negadi.
