June 1st, 2009


Infiltrator Systems, Inc., a portfolio company of Graham Partners, has acquired Ring Industrial Group, L.P., the manufacturer of EZflow™ expanded polystyrene drainfield systems. Graham Partners, a leading private equity firm focused on investing in mid-sized manufacturing companies, initially acquired Infiltrator in September 2005. The addition of the EZflow™ product line is part of Infiltrator’s strategy of offering innovative and high quality wastewater management products. Infiltrator offers a broad family of products that save septic installation professionals time and money.

Rob Newbold, a Managing Principal at Graham Partners, stated, “We have a long history of backing water management companies at Graham Partners, and we believe the increased attention being focused on this critical natural resource bodes well for our investments serving the water industry. In particular, Infiltrator has considerable potential to further develop wastewater management products that offer compelling features and benefits customers and end-users, which are environmentally favorable.”

“Graham Partners has been an excellent investment partner – their financial and strategic support has enabled us to pursue this exciting opportunity,” says Roy Moore, President and CEO of Infiltrator Systems. “Over the next several months, Infiltrator and EZflow™ will integrate resources to generate substantial cost synergies while continuing to maintain and exceed the service needs of our combined customers.”

EZflow™ products are well established in the onsite industry with over 18 years of success and installations in 36 states and provinces. EZflow™ polystyrene aggregate systems are engineered for optimal absorption efficiency in the disposal of effluent. Modular, bundled configurations make for fast, easy installations in septic leach fields and drainage applications. Manufactured from recycled materials rather than energy-intensive mined natural resources, EZflow™ is an excellent addition to Infiltrator’s suite of green products.
