The Province’s ‘Living Water Smart’ Water Plan sets a goal of achieving 33 percent more efficiency in
water use by 2020. Assuming that the province is successful in achieving this reduction in the South
Cowichan area, a 33 percent saving in water use by 2036 was used to form the basis of a second
scenario for estimating residential water demand. Scenario Two includes the assumptions applied to
Scenario One (Targeted Densification), and adds the 33 percent reduction in water use. Hence, Scenario
Two is called “Targeted Densification and Water Efficiency.”
Tables 26 and 27 below identify residential water demand estimates, by watershed and unit type, for the
Targeted Densification and Water Efficiency scenarios. These estimates are based on the household unit
counts shown in Table 25.
