Amaphrojekthi amakhulu amanzi avame ukudinga izingxenye zamapayipi ezinamandla okugeleza okuphezulu kanye nezindleko zokukhiqiza ezisebenzayo. Ipayipi elishiselwe i-Spiral lisetshenziswa ezindaweni eziningi zokuhlinzeka ngamanzi, i-drainage, ukuhlanza indle, ukuchelela, kanye namaphrojekthi wokwakha kamasipala. Izinto eziyisethenjwa zichaza ukuthi ipayipi elikhulu elivunguzayo elinobubanzi ngokuvamile lingaphezu kwemitha elingu-1 ububanzi, futhi ipayipi le-DN2500 lingase libe nobubanzi bangempela bangaphandle phakathi kuka-2500 no-2520 mm. Ubukhulu bezindonga bungasukela ku-8 mm kuye ku-25 mm noma ugqinsi.
Umzila wokukhiqiza uqala ngekhoyili yensimbi. I-strip iyalinganiswa, inqunywe, futhi yakhiwe ngama-roller, futhi igebe le-weld lilawulwa ngaphambi kokushiselwa. Izintambo ezikabili-ezikabili{3}}ezimbili{3}}ze-arc ezicwiliswe emanzini zisiza ukuvikela umthungo. Emapayipini amakhulu, ukuhlolwa kokushisela kubalulekile ngoba umthungo omude uhamba kuzo zonke izingxenye zamapayipi. Ukuhlolwa kwe-ultrasonic okuku-inthanethi nokuhlolwa kwengcindezi kungafakwa ngokuya ngephrojekthi.
Ngolayini wamanzi, umthengi kufanele aqinisekise ububanzi bangaphakathi, ukujiya kodonga, ubude, impahla yensimbi, isidingo sokumboza, kanye nefomu lokugcina. Eminye imigqa idinga amandla okuthutha kuphela, kuyilapho eminye idinga{1}}i-anti-corrosion coating noma isivikelo sangaphakathi. Uma ipayipi lizosetshenziswa emzileni ongcwatshiwe, isimo senhlabathi kanye nokwelashwa okuhlangene kufanele kucatshangelwe ngaphambi kokukhiqizwa kokugcina.
