Ngokukhawuleza kokufudukela kwabantu ezidolophini kwilizwe lethu, iintlekele ezimanyumnyezi zenzeke kwezinye iindawo. NgoJulayi ka-2021, iPhondo laseHenan ladibana neemvula ezinkulu kakhulu, ezibangele ukugcwala kwamanzi esixekweni kunye nezikhukhula zikaloliwe ohamba ngaphantsi komhlaba, okubangele ilahleko enkulu yezoqoqosho kunye neengxwelerha. kunye nezithuthi ezikhubazekileyo, ezichaphazela kakhulu ubomi babahlali basekuhlaleni. Ezi ngxaki zamanzi zingumphumo wokwandiswa okuqhubekayo kokwakhiwa kwedolophu, ukwanda okuqhubekayo kwendawo yokwakha, kunye nokuncitshiswa kwendawo eluhlaza. Zikwabonisa ukungonelanga komthamo wokukhupha amanzi enkqubo yokuhambisa amanzi ezidolophini.
Kwiminyaka yakutshanje, ukwakhiwa kwesixeko sesiponji kuye kwaba ngomnye wemisebenzi ebalulekileyo yokwakhiwa kwedolophu kunye nokuguqulwa.
Kwiimfuno zolwakhiwo lwezixeko zesipontshi, kukhankanyiwe ukuba grey kunye nohlaza kufuneka zidityaniswe, izibonelelo zophuhliso ezinempembelelo ephantsi kufuneka zidityaniswe neenkqubo zokuhambisa amanzi kamasipala, kunye neendawo zophuhliso olunempembelelo ephantsi kufuneka zisetyenziswe ukuphinda kusetyenziswe amanzi emvula xa imvula incinci, amanzi emvula. kumphezulu wendlela iyaqokelelwa ize ikhutshwe kwangexesha ngenkqubo yokuhambisa amanzi kamasipala xa imvula ininzi. Ingxaki yokutshona kwamanzi ezidolophini ayibonakali nje kuphela kwindawo enyiniweyo eluhlaza yesixeko, kodwa nakumthamo ongonelanga wokukhupha amanzi enkqubo yokuhambisa amanzi emvula yesixeko.
Njengenxalenye ebalulekileyo yenkqubo yokuhambisa amanzi ezidolophini, imijelo yokuhambisa amanzi idlala indima yokuqokelela amanzi emvula. Ithambeka kunye nezixhobo ezamkelwe kuyilo lwemijelo yokuhambisa amanzi zinokudlala indima yokuguqula, ukukhawulezisa ukutsalwa kwamanzi emvula, kunye nokunciphisa ngokufanelekileyo ukwenzeka kwamanzi edolophu. . Iidreyini ezincamisayo ziindlela zamanzi emvula ezisekwe ngamaxesha athile ezindleleni nakwiipavumente ukuze ziqokelele kwaye zikhuphe amanzi emvula. Iidreyini ezinqamlezileyo ziindawo zokuphuma kwamanzi emvula eziqhubekayo ezilungelelaniswe ecaleni kwendlela kunye neepavumente, ezidibanisa zonke iindawo zokukhupha amanzi emvula kumgca. Banomsebenzi wokuqokelela ngokukhawuleza amanzi emhlabeni, ukuvumela amanzi emvula aphantsi ukuba asasazwe ngokufanelekileyo kuthungelwano lwemibhobho yamanzi asezidolophini kwaye aphume.
Kwixesha elidlulileyo lokucwangciswa kwedolophu kunye noyilo, ngenxa yoqwalaselo lweendleko, iindawo ezininzi zasezidolophini zazisetyenziselwa imisele yamanzi. uqhelene nengxaki yokuvaleka komjelo wokukhupha amanzi, okukhokelela ekuqokeleleni okukhulu kwamanzi kuloo ndawo yokukhupha amanzi. Ukongezelela, ngexesha lemvula eninzi eqhubekayo, kulula ukubangela ukuqokelela kwamanzi endleleni ngenxa yokungonelanga kwamanzi okukhupha amanzi, okuchaphazela ukuhamba kwabantu imihla ngemihla.
Ngoko ke, ngophuhliso lwezixeko, inkqubo yokuqala yokukhupha amanzi yesixeko kufuneka iguqulwe, kwaye imijelo yemisele yamanzi enendawo enyiniweyo yokukhupha amanzi ithatyathelwe indawo yimijelo enqamlezileyo enemijelo emikhulu yokuhambisa amanzi. zenzelwe ukulungelelanisa ngokuqhubekayo iindawo zokukhupha amanzi zibe ngumgca.Ukuzinza kwe-drainage ye-drain ye-drain drainage iphuculwe kakhulu, ukwenzela ukuba kungabikho ndawo enkulu yokuqokelela amanzi kwindawo yokuhambisa amanzi ngenxa yokuvalwa kwendawo ethile yokukhupha. kwangaxeshanye, imijelo yomsele enomgca ingasetyenziswa kwiindawo ezininzi. Ukongeza kokufanelekileyo kwiindlela zikamasipala kunye neendlela zokuhamba, zinokusetyenziswa nakwizikhululo zeenqwelomoya, iipaki zemizi-mveliso nakwezinye iindawo. Linear umsele idreyini ziinkqubo iimodyuli iqulunqwe ezahlukeneyo amacandelo. Indibaniselwano yemodyuli yeenkcukacha ezahlukeneyo zinokuhlangabezana neemfuno ezahlukeneyo zabathengi. Ingqikelelo yayo yoyilo eyodwa ikwadala indawo eyongezelelekileyo yokucinga kubayili. Yimveliso ethembekileyo nethembekileyo kwintsimi yolwakhiwo lwanamhlanje kunye nenye yezinto ezibalulekileyo zenkqubo yokuhambisa amanzi edolophini.
