Watering using the city supply can be a hassle. Normal spraying methods usually only wets the surface plus the evaporation wastes water.
The device depicted is a normal hand held spray nozzle available in all hardware stores. The spray device is removed and the pipe is reversed and attached to the hose. This makes holding the device relatively comfortable.
The pipe is the inserted along a row of plants at probably one foot intervals and the water actually gets to the roots without waste of water. Using this method the time taken is about equivalent to spraying and more effective, since the water actually gets to the root area.
The hydraulic effect of the stream makes inserting the pipe into the ground effortless.
Very clever! Irrigation is a major issue here, since we don't have rain from April to November. This year I finally went for a major upgrade to my drip irrigation system to handle about 1000 sq ft of beds. When I went from hand watering to drip, it cut my water consumption by about 2/3rds, and gets the water to exactly where the plant needs it.
