Ukusebenza kahle kwedolobha kuncike kunethiwekhi yamapayipi angaphansi komhlaba. Lezi zisebenza “njengezitsha zegazi” zomuzi, zenza imisebenzi ebalulekile njengokuthuthwa kwamanzi nokukhipha amanzi. Emkhakheni wamapayipi kamasipala,I-GKBMIpayipi, ngobuchwepheshe bayo obuphambili kanye nemikhiqizo yekhwalithi ephezulu, inikeza ukusekelwa okuqinile kokwakhiwa kwengqalasizinda yasemadolobheni.
Emkhakheni wokuphakelwa kwamanzi,I-GKBMAmapayipi amanzi e-Pipeline's polyethylene (PE) asebenze kahle kakhulu. Lolu hlu lomkhiqizo luhlanganisa ukucaciswa okungu-29, kusukela ku-dn20 kuyedn1200, namazinga wokucindezela ayisishiyagalombili ukusuka ku-0.4 kuye ku-2.0 MPa kanye nezinhlobo zemikhiqizo eziyi-184. Ngesikhathi senqubo yokukhiqiza, okokusebenza okusha okungeziwe kusebenzisa uhlelo lokuqapha nokulawula ukujiya kodonga oluku-inthanethi, olungalimazi, oluzenzakalelayo ukuze kuqinisekiswe ukujiya kodonga lwamapayipi okufana nokuqina. Ngaphezu kwalokho, yonke imikhiqizo yakhiwe nge-polyethylene ephezulu ye-PE100-grade, engenazo izinto ezigaywe kabusha, ezingenazo izinsimbi ezisindayo, futhi ezingenabuthi futhi ezinobungani nemvelo, ziqinisekisa amapayipi ahlanzekile futhi ahlanzekile. Ingakhiqiza imikhiqizo enobubanzi obufika kuyedn1200 mm namazinga wokucindezela ayisishiyagalombili ukusuka ku-0.4 kuye ku-2.0 MPa. Iphinde iziqhayise ngokuzimela kanye nobuchwepheshe bokulawula ukucutshungulwa obuzimele obuthuthukisiwe bobubanzi obukhulu, amapayipi anezindonga eziwugqinsi, kanye nesistimu yokulawula ezenzakalelayo edijithali. Lokhu kuqinisekisa ukusebenza kwamapayipi okuzinzile nokuhle kakhulu, nempilo yesevisi engaphezu kweminyaka engama-50. Lawa mapayipi asetshenziswa kakhulu ezinhlelweni ezinkulu zokuphambukisa amanzi, ukuphakelwa kwamanzi komasipala nezindawo zokuhlala, ukuhlanzwa kwamanzi ezimbonini, kanye nezinhlelo zokuphakelwa kwamanzi ezingenawo imisele.
Emkhakheni we-drainage,I-GKBMIpayipiiphinde iphumelele ngamapayipi ayo okudonsa amanzi kamasipala anobubanzi obukhulu. Imikhiqizo yayo ihlanganisa amapayipi kathayela anezindonga ezimbili ze-PE, amapayipi ensimbi aqiniswe yinsimbi ye-PE, kanye namapayipi amanxeba okuvunguza odongeni e-PE, amboza osayizi abaveladn200 kuyedn1600. Le mikhiqizo ihlangabezana nezindinganiso zikazwelonke zezinkomba eziyinhloko njengokuqina kwendandatho nokuguquguquka kwendandatho. Ngaphezu kwalokho, udonga lwangaphakathi lwale mikhiqizo lufakwe amanzi emvula kanye nezithasiselo ezimelana nokukhuculula indle nezimelana nokugqwala, okuthuthukisa kakhulu ukuzinza nokusebenza nempilo yokuphila kwamanethiwekhi amapayipi okukhipha amanzi. Le mikhiqizo ingasetshenziswa kumaphrojekthi kamasipala, kanye nasezimbonini, ezolimo, ezemvelo, ekwakhiweni kwemigwaqo, namapayipi okuthuthwa kwendle asemayini.
Kusukela ekuhanjisweni kwamanzi kuya ekukhipheni amanzi,I-GKBMIpayipi ihlinzeka ngezixazululo zomkhiqizo ezinokwethenjelwa zokwakhiwa kwamapayipi kamasipala ngokusungula izinto ezintsha zobuchwepheshe kanye nokulawulwa kwekhwalithi okuqinile, ukusiza inethiwekhi yedolobha “yemithambo” ukuthi isebenze ngendlela enempilo futhi ephumelelayo, ebeka isisekelo esiqinile sentuthuko esimeme yedolobha.
