Mandatory water use restrictions may limit the total quantity of water that can be used or restrict
particular water uses. Empirical evidence regarding the effects of these
programs is mixed. Summer 1996 water consumption restrictions in
Corpus Christi, Texas, including prohibitions on landscape irrigation and car washing, did not prompt statistically significantwater savings in
the residential sector (Schultz et al., 1997). A longer-term program in
Pasadena, California resulted in aggregate water savings (Kiefer et al.,
1993), as did a program of mandatory water use restrictions in Santa
Barbara, California (Renwick and Green, 2000).
