In 2015, Fuzhou was ranked as the 10th fastest growing metropolitan area in the world by Brookings Institution. In 2018, the municipal government issued a regulation to immediately begin upgrading the existing water supply infrastructure that serves approximately 310,000 households, increasing the use of stainless steel piping and decreasing the use of plastic and galvanized piping in the water supply infrastructure, due to the potential contamination plastic and galvanized piping material may cause to the water. To conform to the new regulation, Fuzhou Water Group organized a tender where leading stainless steel pipe manufacturers in China were invited to bid for the next year's stainless steel pipe procurement program.
