Unyango lwaManzi amdaka aseMaphandleni oluSetyenziswe kwiindawo ezahlukeneyo ngoNyango oluNcinci lwaManzi amdaka eJohkasou

Kwimimandla emininzi yasemaphandleni kwihlabathi liphela, iziseko zamanzi amdaka ezikwindawo enye zihlala zinqongophele okanye azikho. Izisombululo zemveli ezifana nezityalo ezinkulu zonyango okanye iinethiwekhi zemibhobho ezikude zihlala zingenakwenzeka ngenxa yeendleko eziphezulu, inani labantu abasasazekileyo, kunye nemida yomhlaba. Oku kudala imfuno ekhulayo yokwahlulwahlulwa, okulula ukuyifaka, kunye neendleko eziphantsi.iinkqubo zokunyanga amanzi amdaka—ingakumbi kwiindawo ezincinci, iintsapho, kunye neelali ezikude.

Umngeni woLawulo lwaManzi amdaka aseMaphandleni

Iindawo zasemaphandleni zijongene neengxaki ezininzi eziqhubekayo xa kufikwa ekucocweni kwamanzi amdaka emakhaya:

• Ukunqongophala kwenethiwekhi zamanzi amdaka ezisebenza kwindawo enye, nto leyo eyenza ukuqokelelwa kwamanzi amdaka kube nzima kwaye kubize kakhulu

• Iintsapho ezisasazekileyo kunye nokukhutshwa kwamanzi kwiindawo ezincinci, ezifuna izisombululo zonyango eziguquguqukayo nezincinci

• Uhlahlo-lwabiwo mali olulinganiselweyo kunye nobunzima bokulungelelanisa imisebenzi emikhulu yoluntu

• Ukukhulisa imithetho yokusingqongileyo, kufuna imigangatho ephezulu yokukhupha amanzi kunye nokukhuselwa kwendalo

Le mingeni ifuna inkqubo encinci, ezimeleyo, nesebenzayo, kodwa elula ukuyigcina nokuyisebenzisa.

Isisombululo: I-Compact LD-SA Johkasou

II-LD-SA compact engcwatywe i-johkasou encinci (STP)Ibonelela ngesisombululo esifanelekileyo sokucocwa kwamanzi amdaka asemaphandleni ngendlela esasazekileyo. Yenzelwe ngokukodwa ukucocwa kwamanzi amdaka asekhaya kunye namanzi amdaka kwindawo leyo, kwaye umthamo wokucoca yonke imihla yi-1-2m³/ngosuku, nto leyo eyenza ukuba ifaneleke:

• Imizi nganye nganye

• Amaqela eelali

• Iifama

• Iindawo zokuhlala ezikude kunye neendlu zeendwendwe

• Iindawo zangasese zikawonke-wonke ezisemaphandleni

Iimpawu eziphambili kunye neenzuzo

• Uyilo oluphantsi komhlaba olupheleleyo: Lufuna indawo encinci yomhlaba kwaye ludibana nomhlaba ngaphandle kokuphazamisa indawo engqongileyo

• Ukusetyenziswa kwamandla okuphantsi kunye nengxolo ephantsi, inqanaba lengxolo elingaphantsi kwama-45 decibels

• Umgangatho Ophezulu Wokungcola: Amanzi acociweyo ahlangabezana nemigangatho yokukhupha amanzi, kwaye kwezinye iimeko, anokusetyenziswa kwakhona ekulungiseni igadi okanye ekunkcenkcesheleni, nto leyo ekhuthaza ukuphinda kusetyenziswe izixhobo

• Iimfuno Eziphantsi Zokugcinwa: Ukubeka esweni okukrelekrele iiyure ezingama-24

Ukuhambelana kweenjongo zoPhuhliso lwaseMaphandleni

Njengoko oorhulumente kunye namagunya okusingqongileyo begxininisa ukuvuselelwa kwamaphandle, ukuphuculwa kococeko, kunye nolawulo lwamanzi olusasazwa kwiindawo ezahlukeneyo, i-LD-SA johkasou inika isicwangciso esifanelekileyo:

• Izalisa umsantsa apho iinethiwekhi zemibhobho zingekhoyo okanye zibiza kakhulu ukuzakha

• Ixhasa unyango "oluvela kwindawo ethile", olulungele iindawo zasemaphandleni ezinemizi ethe tyaba

• Ikhawulezisa ukusasazwa kweprojekthi—ilungele iiprojekthi ezixhaswa yinkxaso-mali okanye zexesha elithile ezineshedyuli exineneyo

• Ihlangabezana nokuthobela imithetho yokukhupha amanzi kwiindawo ezincinci, inceda uluntu ukuba luphumelele uhlolo lokusingqongileyo kwaye luhlangabezane neemfuno zomthetho

Isiphelo

Njengoko uluntu lwasemaphandleni lufuna izisombululo ezisebenzayo nezingabizi kakhulu zokulawula amanzi amdaka asekhaya, i-johkasou encinci yendle efana ne-LD-SA iba lukhetho olukhethwayo. Ngenxa yokusebenza okuthembekileyo konyango, iindleko zokusebenza eziphantsi, kunye nokuziqhelanisa neendawo ezikude, ezi nkqubo zivumela amanzi acocekileyo kunye neendawo ezisempilweni—ngaphandle kwesidingo seziseko ezintsonkothileyo.
