Citizens do not refuse to drink reclaimed water, they are not allowed to drink reclaimed water. It is used as a source to help manage the groundwater basins though. Reclaimed water that is pumped into a basin and then pumped out later for use, is no longer consider reclaimed water. There are a number of basins in CA. I am somewhat familiar with the management of the two basins in LA County and the one in Orange County.
I beg to differ esp. with desalination, polls showed people would refuse to allow that water into a public water system.
If by referring to recycled water carried in purple piping you mean people aren’t allowed to drink it because it was not processed for drinking then you are correct.
