Mapaipi a HDPE ndi olimba kwambiri, amakhala nthawi yayitali, komanso amalimbana ndi ming'alu ya kupsinjika ndipo sangawonongeke ndi mankhwala ambiri komanso zinthu zina zamoyo. Makhalidwe a mapaipiwo ankatanthauza kuti safunika kukonzedwa bwino poyerekeza ndi zipangizo zina za mapaipi ndikuonetsetsa kuti madzi akuyenda bwino nthawi yonse yomwe amagwira ntchito.
Njira yothetsera mavuto a ChuangRong inali ndi mapaipi, ma electrofusion couplers, makina olumikizira magetsi, chithandizo cha uinjiniya, zida zapadera zoyikira, ndi maphunziro.
Ntchito izi zikuphatikizapo kufukula mapaipi m'misewu, kuyika mapaipi mu ngalande, kulumikiza, kuyesa madzi ndi kudzazanso ndi dothi lofukulidwa. Dholaikhal Main Road, Begum Gonj Lane Main Road, Doyagong Main Road, Kaptan Bazar To Gulistan Main Road, Wari Main Road, Bahadur shahpark road, Gendaria new road, Shahid Faruk Road ndi zina zotero ndi misewu ikuluikulu (m'lifupi > 4m) m'dera la subproject.
