Pn 12 .5 I-Coefficient Yokunweba Okuphansi Ukuphuza Ipayipi Le-PPR Amanzi Abandayo
Ngokusho kwe-“Drinking Water Ordinance kanye neminye imithetho eminingi yamazwe ngamazwe yezinhlangano zezempilo ezifana ne-WHO, ukusetshenziswa noma ukusetshenziswa kwamanzi akufanele neze kube yingozi empilweni yabantu.Ukwakheka kwamanzi amakhemikhali kanye ne-microbiological kufanele kuqashelwe iziphathimandla zezempilo, kodwa futhi nabaphathi besikhungo ukuze kuqinisekiswe izinga lamanzi aphuzwa kakhulu.
Ngohlelo lwethu lwamapayipi oluhlanzekile, ipayipi eliluhlaza izinga elihle lamanzi okuphuza lingagcinwa unomphela.Akukona nje kuphela ukuthi imelana nokugqwala kodwa iphephile ngokomzimba kanye ne-microbiologically, futhi ayifaki iphunga noma ukunambitheka emanzini ageleza ngawo.Ukufaneleka kwayo kwezobuchwepheshe kanye nokusebenza kwayo kufakazelwe emhlabeni wonke amashumi eminyaka.Izinhlobonhlobo zamapayipi nezixhumi ezihlukene ezingama-450 ezinobukhulu ukusuka ku-20 kuye ku-355 mm ziqinisekisa ukufakwa okuphephile nokulula Amapayipi amapayipi enziwe ngaphambili ayatholakala.

1. Hlangana nezindinganiso eziqinile zamanzi okuphuza eYurophu naseMelika
2. Ayinambala futhi ayinaphunga, ayikho iphunga elicasulayo lapho i-hot-melt welding
3. Ukumelana nokugqwala okuhle, akukho mphumela wamakhemikhali kuwo wonke ama-ion emanzini namakhemikhali esakhiweni
4. Ukumelana namapayipi kuncane, akukho ukukala
