Water conservation

Water is a precious natural resource and its sustainable management is essential to protect the water environment and to meet current and future demand. Population, household size and growth and affluence all affect how much water we use. Factors such as climate change are also likely to put supplies under greater pressure in the future, making it important that we adopt more efficient water use patterns.
