Roberts Filter
Infinity™
The Infinity™ 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.
Trilateral™
The Trilateral™ Air/Water Underdrain from Roberts Leotech offers water producers and their consulting engineers flexibility to choose an underdrain system for their specific needs.
The Trilateral underdrain uses a passive air-scour approach to replace conventional, water-only backwashes. This proven design offers a low cost, easy to assemble combined air/water or water-only underdrain installation.
Clay Tile
A long history of proven performance and versatility establish the tile underdrain as a traditional technology underdrain system. Over the past two decades, our "dual-parallel lateral" ceramic block underdrain system has gained wide acceptance in both new and retrofit applications.
Aries™
The Aries® Managed Air System is a revolutionary filter air scour system. The Aries is the preferred method of auxiliary wash for the cleansing of a filter, since it provides thorough cleansing of the entire filter bed versus surface wash systems or passive air systems which are only effective in the top layer of the filter bed.
