The InfinityTM Underdrain is a dual-lateral system, manufactured from a corrosion resistant lightweight material. The overall height of the underdrain when installed is a nominal 6". Each lateral is custom manufactured to the required filter width. Customized lateral lengths in excess of 30 feet without a joint can be manufactured.
The Infinity Underdrain eliminates potential joint failures since no assembly of individual lateral runs is required to assemble a complete lateral. There are no joints requiring snaps, clips, grout or other attachment devices requiring O-rings, tongue and groove connections or gasketing between blocks to assemble a complete lateral run. Each Infinity underdrain lateral is shipped to the jobsite completely assembled. Flume openings are pre-cut into each lateral and custom flume blocks are not required.
The Infinity Underdrain exhibits excellent distribution characteristics all with a low profile in order to maximize filter freeboard and bed depth. The top surface of each lateral contains the appropriate number of discharge orifices to assure proper distribution. This feature assures that filtered water will be uniformly collected, and backwash water uniformly discharged into the media placed above the underdrain system.
The Infinity Underdrain can be supplied with or without a porous plate. The porous plate eliminates the need for the gravel support and the unique rail mount system provides a positive mechanism to prevent media migration into the underdrain.
