Figure 5.5 Total water use vs. dwelling units, properties built after 1995
The average water use by billing type for the manager survey respondents is shown in
Figure 5.6, and the differences in water use compared to in-rent are shown in Figure 5.7. Water
use in submetered properties was significantly lower than in in-rent properties, but no
statistically significant differences were observed between RUBS properties and in-rent
properties, or between hot water hybrid properties and in-rent properties (see Table 5.10).
