Use a broom and bucket of water for washing down the patio rather than a steady flow of water from the hose.
Install a water butt in the garden to collect the rain water. This will mean you always have water to use for watering the garden without the need to use fresh water from the hose.
Using mulch on the garden with help the soil retains water so will mean you won't have to water the garden as often.
Don't overuse hoses or sprinklers in hot weather. A sprinkler can use as much water in an hour as a family of four will use in a day. Your lawn only really needs watering once a week and it is better to water in the morning when the temperature is lower and evaporation is less.
Research your plants, some actually thrive in drier conditions and will not benefit from over watering.
Use a sponge and bucket of water to clean your car or if you use the hose, ensure you use a shut off nozzle so the water is not constantly running.
