In this video we are going to show you how we assemble this End Riser that goes at the end of the Aquifer Pipe. The purpose of it is that when the Aquifer Pipe gets filled up with water this becomes like a reservoir. The water goes up to 90 and into the riser area. This is to give the soil time to absorb the water. As the soil absorbs it the water just goes back down into the Aquifer Pipe.
