Water usage. Water conservation. Why we need to be "green"

Good water is a precious resource, essential to our survival. It is important to care about using water wisely so there will be enough for future generations. By using water wisely, you help ease the burden on water treatment plants, storage and distribution facilities. That means utilities can delay building new facilities, which can be expensive. Reducing the amount of water consumed in the region allows money that would have otherwise been spent on expanding water supply infrastructure to be used for other projects such as drinking water treatment.

There are basically four main reasons why we should conserve water.

- Save money
- Save energy
- Protect the environment
- Ensure water for future generations
