The benefit of an enclosure is that it keeps jumpers from falling off a trampoline or impacting the frame. [3] [4] Safety net enclosures vary from one manufacturer to another, such as the opening in the net so that jumpers may enter and exit the trampoline. The design of such openings may include: snap/Velcro system, zipper, or overlapping ...
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface.
The ground or obstructions on the ground – jumpers would hit as a result of falling off. Alexander's goal was to increase the trampoline's safety by re-engineering the spring technology. In 1999, Alexander released his first prototype utilising glass-reinforced plastic rods, and the first commercial versions began selling in late 2004.
When used in the proper conditions, it allowed people on upper floors of burning buildings an opportunity to jump to safety, usually to ground level. Invented in 1887, the device was used with varying degrees of success during several notable fires in the 20th century. Due to advances in firefighting technology, it became obsolete by the 1980s.

Effluent levels near the drain field will rise toward the ground surface to preserve that vertical distance difference if groundwater levels surrounding the drain field approach the effluent level in the disposal trench. [7] Frozen ground may seasonally reduce the cross-sectional area available for flow or evaporation.
Drainage options for the construction industry include: Point drainage, which intercepts water at gullies (points). Gullies connect to drainage pipes beneath the ground surface, so deep excavation is required to facilitate this system. Support for deep trenches is required in the shape of planking, strutting or shoring.
