Can I use excess water collected from activities such as washing vegetables and use it to water plants?
Yes. Finding ways to collect water that would be otherwise be going down the drain and using it to water your landscape is a waterSmart way to keep your plants hydrated without needing to turn on the hose. Some of the most popular ways to collect water are putting a bucket in the shower, pouring unwanted drinking water (for pets or humans) into a bucket and even using a container to salvage water from the rinse cycle of your washing machine. If you are watering vegetable plants you intend to eat, you should use strong discretion as to the quality of water you are irrigating them with.
