Siwadinga nini amaphampu amanzi amabili ukuze asetshenziswe ngaphakathi nangaphandle?

Uma uhlangabezana nesidingo sokugeleza esincane kakhulu noma esikhulu, uma izinga lokugeleza leyunithi efanayo likhulu kakhulu noma lingaphansi kakhulu kwezinga lokugeleza kokukhiqiza, kunezindlela ezintathu zokwelashwa:

1. Asikho isidingo sokucindezela kwamanzi okukhiqiza, futhi ukusetshenziswa kwamanzi kuncane kakhulu.I-bypass yengezwa ukuxazulula izidingo zokukhiqiza zeklayenti;
2. Uma amanzi akhiqizwayo eklayenti enezidingo zomfutho ophezulu kanye nokugeleza kwamanzi kukuncane kakhulu, amaphampu amabili kufanele asetshenziselwe ukujikeleza kwangaphakathi nangaphandle;
3. Umthamo wamanzi okhiqizwayo mkhulu kakhulu kunomthamo wamanzi odingwa yiyunithi.Kungakhathaliseki ukuthi kunesidingo sokucindezela, kufanele sisakazwe ngaphakathi nangaphandle, futhi ipompo yamanzi yokukhiqiza yangaphandle kufanele yengezwe;
