Zhejiang Regional Observation: How can "water-scarce" cities allow large water users to develop with peace of mind? Quality-based water supply across the region has become the only way for local high-quality development. Yiwu has invested 20 million yuan in recent years to transform 64 high-water-consuming enterprises into water-saving facilities.

It has built 70 sets of reclaimed water reuse equipment. The city has also "significantly discounted" the price of water by quality.
