Qhov zoo: tus nqi nruab nrab, kev ua haujlwm ruaj khov, rwb thaiv tsev kub, tiv thaiv corrosion, du sab hauv phab ntsa tsis muaj qhov ntsuas, kev nyab xeeb thiab txhim khu kev qha piping system, impermeable, thiab kev pabcuam lub neej tuaj yeem ncav cuag 50 xyoo.
Qhov tsis zoo: kev tsim kho tshuab siab, cov cuab yeej tshwj xeeb thiab cov kws tshaj lij yuav tsum tau tsim kho kom muaj kev nyab xeeb ntawm lub cev.
