Posachedwapa, mzere wopanga chitoliro cha 1600mmPE udayambika bwino mufakitale yamakasitomala ndipo udayenda mokhazikika. Makasitomala adalankhula bwino za luso komanso ukatswiri wa mainjiniya a Grace!

Kupyolera muzaka zambiri zothandiza, Grace wapanga ndi kupanga chitoliro cha madzi a HDPE ndi mzere wopangira chitoliro cha gasi chokhala ndi dongosolo lapadera, kamangidwe kake katsopano, makina apamwamba kwambiri, ntchito yabwino komanso yokhazikika komanso yodalirika yopangidwa mosalekeza. Mapaipi opangidwa ndi mzerewu ali ndi kukhazikika pang'ono, mphamvu, kusinthasintha kwabwino, kukana kuyandama, kukana kupsinjika kwa chilengedwe komanso magwiridwe antchito abwino amawotcherera, ndipo yakhala chisankho choyamba pamapaipi amafuta akutawuni ndi mapaipi operekera madzi akunja.
