In 1979 Jim Nichols, a plastics-design consultant, looked out the window of his home and saw a homeowner’s worst nightmare; the ground was oozing and bubbling wastewater as a result of a failed septic system. He needed to replace part of his gravel and pipe leach field.

When the installation contractor came to replace his leach field he watched the process with a curious eye. When they finished up the leach field replacement Jim told to Sid Holbrook, the contractor, “We could probably come up with something better in plastic.” Sid agreed and told Jim when he was serious about it that he’d help him raise money to give it a try.

A few years later Jim approached Sid with the design for the Infiltrator chamber. Together, Jim and Sid sought out investors to finance manufacturing and testing of the Infiltrator chamber system and Infiltrator was born.

In 1987 Infiltrator Systems entered the market selling the Infiltrator chamber system as an alternative to the decades-old traditional gravel and pipe leach field. The key differentiator that the Infiltrator chamber system brought to the market was that contractors could install a complete system in half the time of a gravel and pipe leach field. Contractors quickly bought into the concept. For the first year in business they predicted a loss; instead Infiltrator Systems made an $80,000 profit, selling more than 30,000 Infiltrator chambers.

In 2015 Infiltrator Systems became Infiltrator Water Technologies to more accurately describe the company’s offerings beyond the onsite wastewater industry.

Today Infiltrator manufactures and sells multiple product lines for the onsite wastewater and water industry. With innovative products and service, ISO 9001 certified manufacturing facilities, leading creative recycling solutions and the development of new subsidiaries, Infiltrator is poised to offer a total approach to water quality. Our future lies in a global effort to identify and develop new technologies that improve water quality and wastewater management worldwide.

In 2018, Infiltrator expanded into the advanced wastewater treatment segment of the industry with the acquisition of Delta Environmental assets from Pentair Flow Technologies and has reestablished the Delta brand to Delta Treatment Systems, LLC. Delta Treatment Systems manufactures and sells products for residential and commercial advanced wastewater treatment including custom package treatment plants and ECOPOD and Whitewater models. Delta Treatment Systems was rebranded to become Infiltrator in 2024.

Infiltrator further expanded its reach in the onsite industry with the acquisition of Presby Environmental, Inc. (PEI) in April 2019. Based in Whitefield, NH, PEI manufactures combined wastewater treatment and dispersal systems. With this acquisition Infiltrator has increased its product offerings to include Advanced Enviro-Septic, Enviro-Septic and Simple Septic. Presby Environmental, Inc. was rebranded to become Infiltrator in 2024.

In 2019, Infiltrator was acquired by, and now operates as a wholly-owned subsidiary of, Advanced Drainage Systems, Inc. (ADS).

Both Infiltrator and ADS share a similar vision and values and remain committed to developing innovative, best-in-class products while maintaining a dedication to safety, operational excellence, and sustainability through our recycling activities.
