4. geographic condition

Answer 2

FACTORS:

Rainfall, temperature and evaporation rates – Precipitation and temperature varies widely

across the state. Areas with high temperature and low rainfall need to use more water to

maintain outdoor landscaping. Even within the same hydrologic region or the same water supply

district these factors can vary considerably, having a significant effect on the amount of water

needed to maintain landscapes.

 Population growth – As communities grow, new residential dwellings are constructed with

more efficient plumbing fixtures, which causes interior water use to decline per person as

compared to water use in older communities. Population growth also increases overall demand.

 Population density – highly urbanized areas with high population densities use less water per

person than do more rural or suburban areas since high density dwellings tend to have shared

outdoor spaces and there is less landscaped area per person that needs to be irrigated.

 Socio-economic measures such as lot size and income – Areas with higher incomes generally

use more water than areas with low incomes. Larger landscaped residential lots that require

more water are often associated with more affluent communities. Additionally, higher income

households may be less sensitive to the cost of water, since it represents a smaller portion of

household income.

 Water prices – Water prices can influence demand by providing a monetary incentive for

customers to conserve water. Rate structures have been established in many districts to

incentivize water conservation, but the effectiveness of these rate structures to deter excessive

use and customers sensitivity to water prices vary.
