More than a century ago, in 1889, we designed and patented one of the earliest water filters. Today, we’re still on the cutting edge. Across the U.S. and around the world, Roberts continues to work with some of the smartest companies and engineers on the planet to answer the industry’s demand for customized, flexible solutions and efficient operations. Below is a timeline of our historic accomplishments:

  • Roberts is the largest family-owned water treatment company in the U.S.
  • Expands U.S. manufacturing and research and development facilities.
  • Introduces the industry’s first jointless underdrain
  • 1990s: Develops new systems for sludge removal, air scour, filter monitoring and real-time adjustments.
  • 1980s: Develops package treatment facility systems, improving efficiency of treating low turbidity water
  • 1960s: Introduces continuous effluent turbidity monitoring to enhance filtration performance for the municipal market
  • 1950s: Charles V. Roberts II pioneers high-rate filtration to the municipal market.
  • Provides water treatment facilities for the Manhattan Project, utilizing highrate filtration clean water for the world’s first atomic energy installations
  • Jesse W. Roberts consolidates efforts into new filtration plants, builds many installations that have been in constant use ever since.
  • Charles V. Roberts oversees development of first Army mobile water purification units.
  • Charles Roberts first patents his household stone filters.
