Mandatory water use restrictions may limit the total quantity of water that can be used or restrictparticular water uses. Empirical evidence regarding the effects of theseprograms is mixed. Summer 1996 water consumption restrictions inCorpus Christi, Texas, including prohibitions on landscape irrigation and carwashing, did not prompt statistically significantwater savings inthe residential sector (Schultz et al., 1997). A longer-term program inPasadena, California resulted in aggregate water savings (Kiefer et al.,1993), as did a program of mandatory water use restrictions in SantaBarbara, California (Renwick and Green, 2000).
