Diesel Powered Irrigation

This is best practice in Hong Kong, a diesel truck hauls water for irrigation of the streetscape. In this case, filmed at Murray road by the AIA building in Central, the truck sits with its engine idling, but not all of the water actually reaches the plants, water is pouring out from the truck bed on to the road surface.

Another variation, the diesel truck cruises the streets at a low speed, with a helper hosing down the plants (Wang Hoi Road, Kowloon Bay, Hong Kong).

If you are really unlucky, one watering truck route meanders along blocking the only lane from Kowloon west leading into the Central/Hunghom tunnel.
