Do California colleges restrict water usage?

My kids both graduated from a private U in CA. Neither mentioned anything about conserving water. D is still living in LA and still has not mentioned anything about drought or water conservation. She loves tub baths but is not as fond of showers. I haven’t noticed any difference in their water-use habits since they have lived in LA. When we visited their campus, it was quite lush, but it was in the 2006-2013 time period.
