Kuyini Ukuvuna Amanzi Emvula?

Ukuvunwa kwamanzi emvula kuyindlela yokubeka amanzi nokuvula amanzi emvula emhlabeni noma ophahleni lwezakhiwo ngamapayipi noma emigodini emanzini okugcina amanzi. Ukuqoqa amanzi emvula avela ophahleni kuhlanzekile kakhulu kunokuqoqa amanzi aphilile emhlabeni.
Kunoma yikuphi, ukuhlanza nokuhlunga amanzi emvula ngaphambi kokusetshenziswa kunconywa. Akugcini nje ukuhlanza amanzi ekusetshenzisweni kwasekhaya noma kwezolimo, kodwa kuzosusa amakhemikhali, inhlabathi kanye nokungcola futhi kuzovimbela amaphampu ukuthi abonakaliswe ngenxa yezinto ezisemanzini.

Indlela Yokwakha Uhlelo Lokuvuna Amanzi

Ukusetha uhlelo olulula lokuvuna amanzi kudinga izinto ezintathu; uphahla, amapayipi noma ama-gutters, ukuhambisa amanzi emvula, kanye ne-tank isitoreji.
Hlanza uphahla kanye namanzi. Uma ama-gutter noma amapayipi kudingeka afakwe, khetha ama-gutter ane-quality UV resistant PVC nezindiza. Qinisekisa ukuthi amaphuphu amancane axhunyiwe ku-tank yamanzi. Qinisekisa ukuthi ama-gutters awela kancane emanzini. Lokhu kuzoqeda ukuqoqwa kwamagqabha namanzi aphelile, kube yindawo yokuzalanisa umiyane.
Noma yimaphi amagatsha alenga phezu kophahla kufanele asuswe ukuze avimbele amaqabunga angena ohlelweni. Sebenzisa izikrini zesikhumba noma izihlungi bese uzihlanza njalo.
Ukukhukhulwa kwamakhemikhali kusuka ekupunizeni kungahlala phezu kophahla bese kuhlanzwa ithangi. Ungafaki izitshalo ngosuku olunomoya.
Uma udweba uphahla, sebenzisa upende oluphephile njengezinsalela zokupenda zingangena emathangi bese zingcolile amanzi.
Hlanza uphahla ngemuva kwemililo endaweni. Ngemuva kwemvula, umlotha nama-debris kungase kugezwe ku-tank, ngaleyo ndlela igqoke amapopu. Khumbula, ukuhlanza uphahla, ukuhlanza amanzi.
Uhlelo lokuhlanza ukuhlanza amanzi ngaphambi kokusetshenziswa lungadingeka futhi lungaba ngendlela:
Isihlungi sesandla
Isihlungi se-Pop-up
Isitimela sokuzinza

Amathangi Okugcina Amanzi

Noma yiliphi ithangi lokugcina amanzi lingasetshenziswa, kodwa qinisekisa ukuthi lihlanzekile futhi linokungena noma ibhathini. Faka itanki elikhulu ngokwanele futhi, uma kungenzeka, ulibeke esisekelweni esinamandla nesinqunyiwe, ephakeme ngokwanele ukuvumela ukuthi amabhakede agcwaliswe kalula emthonjeni wamathangi. Uma ukwakha isisekelo sekhonkrithi, qiniseka ukuthi okungenani ubukhulu obuyi-85 mm.
Ungasebenzisi itanki eyayisetshenziswe ngaphambilini ukugcina noma yini enobuthi njengamafutha, amafutha noma amakhemikhali. Uma kungenzeka, ungasebenzisi tank eyenziwe nge-asbestos. Amathangi wamanzi angenziwa nge-plastic polyethylene, ikhonkrit noma i-zinc ekhonjiwe. Amathangi ensimbi kufanele agqoke ngaphakathi nge-liners grade grade ezifana ne-PVC noma i-polyethylene. Amathangi amanzi epulasitiki angabizi, kanti amathangi okukhonkolo angabiza kodwa agcina amanzi epholile.
Cabanga ukufaka i-tank yokuchichima ukugcina amanzi amaningi kakhulu uma ithangi elikhulu lifinyelela ezingeni elithile. Uma usebenzisa amanzi amathangi njengamanzi okuphuza, qiniseka ukuthi uyililisa kuqala. Kufanele futhi ihlungwe futhi iphathwe nge-bleach. Abacwaningi be-Water Research Commission batusa inkomishi ye-¼ ye-bleach ngamalitha angu-5 000 amanzi.
Gcina ilokhi ethintini lompompi ukuvimbela ukufinyelela emathini amanzi. Vimbela noma ubani ukuba akhuphukele etafuleni, engena ngengozi bese egwaza.
