What National Diversified Sales does

National Diversified Sales (NDS), founded in 1972 in Woodland Hills, California, manufactures and distributes stormwater drainage and irrigation hardware for residential, commercial, industrial, government, golf/parks/recreation, and agricultural end markets. The company pioneered the first plastic catch basin and has built a 50+ year product portfolio spanning channel and trench drains, French drains (EZflow), catch basins, dry wells (Flo-Well), drainage grates, StormChamber underground detention systems, pop-up emitters, permeable pavers (Tufftrack, EZ Roll), drip irrigation (Dura Flo, AccuFlow emitters), and valve/meter/telecom access boxes, plus complementary fittings, clamps, valves, and root barriers. Sub-brands include Raindrip, TECO, BG-FILCOTEN, Dura Slope, Pro-Spec, SureFit, and DesignWorx services. NDS sells primarily through a multi-tier distributor and retailer network with a 'Where to Buy' locator, a FIND-A-PRO certified contractor directory, direct support to civil engineers and specifiers via the DesignWorx team, and the NDSpro.net professional portal; pricing is unit-based, quote-driven for commercial projects, and not publicly disclosed.

NDS operates in the Americas and EMEA (with an EMEA regional headquarters in Trani, Italy managed via TECO Srl) and carries certifications including ISO 9001, ISO 14236, BS 5114, AS/NZ 4129, AS 4020, LEED compatibility, ADA compliance on select grates, and H-20 load ratings on heavy-duty lines. The company had been a subsidiary of Germany-based Norma Group SE prior to being acquired by Advanced Drainage Systems (NYSE: WMS) on February 2, 2026 for approximately $1 billion; NDS now operates as part of ADS's expanded water management segment alongside Infiltrator Water Technologies, and contributed $48.8 million in stormwater revenue in Q4 FY2026 alone.
