Note: Exemptions are in place for certain businesses and functions; and in all cases, freshly laid sod and newly planted shrubs and trees are exempt from such restrictions for a four-week period. Swimming pool covers significantly reduce evaporative losses and can save 11,000–30,000L of water a year. Water holding capacity is determined by the texture of the soil and levels of organic matter. An overfilled swimming pool can lose more water through splashing. Note: There are no per capita residential water use data for 2007 because data for the Municipal Water and Wastewater Survey were not collected that year. Choose a different place on the lawn each time. Automatic systems set to turn on regardless of weather conditions and soil moisture content waste water.
