What we do is we take a fire hydrant, a no parking space associated with a fire hydrant, and we prescribe the removal of the asphalt to create an engineered micro landscape, to create an infiltration opportunity.

But if we did this in every single every fire hydrant we could redefine the emergency.

Fuel is transported from the depot to the aircraft either by road tanker or via a hydrant system.

It's a little bit like designing a fire hydrant, and it has to be easily serviceable you have to know where it is and what it does.
