Drip Watering #4

The Melbourne City council have come up with a great way to water their significant trees. All around the center of Melbourne at the moment you will see the red and white traffic barriers babysitting a big tree. These barriers are designed to be filled with water to make them heavy, in their normal traffic`hjazard management duties, but with the simple addition of a drip hose they can become a personalised tree watering system that the council can refill with recycled water periodically.
