Everybody knows tree roots do need water, therefor we need an opening to let water flow inside the rooting area below pavement. Beside water, air Oxygen is playing an important role for trees to survive underneath pavement. Aeration is key to microbial processes on which trees depend and benefit from. More air at deeper levels means deeper roots and less pavement lifting.

But why use 2 different inlets, one for water and one for air? The AW inlet system provides simultaneous tree irrigation and -aeration from only one opening. Thanks to a design of the inlet, water first runs into the top, a perforated tube, and does not go down into the ventilation duct. The inlet also acts like an overflow when too much water flushes in.

Advantages

• only one inlet ; simultaneous water / air supply
• easy and fast installation
• integrated filter against contamination
• eliminates mistakes when manual irrigating the trees
