Tips
Egg-boiled water
- Do you boil eggs at home? Cool the water you used and pour it for your plants - plants benefit from the calcium. You can keep a bucket and keep storing the water and use it whenever you water your plants.
Water used for boiling/rinsing vegetables
- Water used for boiling potatoes or vegetables. Collect for a day to re-use in the garden.
- Wash your vegetables in a small tub. Re-use this water for your garden/community garden.
Water in restaurants
- In restaurants, don't allow the waiter to re-fill your glass if you don't plan to drink that much water. The leftover water from your table will be thrown away - we lose thousands of litres of water this way in cities every single day. Even better - take your own water bottle whenever you step out. Add some chia seeds in it if making it nutritious will motivate you. :) Or take water in which you have boiled jeera/coriander seeds for a couple of minutes - helps improve your digestion.
