How it's used
This term carries a strong historical resonance for older generations in Hong Kong who lived through severe droughts in the 1960s. It specifically refers to the government policy of turning off the water supply for long periods to conserve resources. While modern infrastructure has made it rare, the term remains a common way to describe any situation where water access is strictly limited.
Examples
If it doesn't rain again, the government will have to ration water.
Do you remember having to queue for water back when water was rationed?

period of water rationing
Common mistake
Do not confuse this with simply turning off a tap or a temporary pipe repair. 制水 implies a large scale, government mandated restriction affecting a whole district or the entire city due to a lack of supply.
