Wavin B.V. is a global manufacturer of plastic pipes, mainly for drainage and water supply purposes.

The company was officially founded in the Netherlands on 5 August 1955, its name deriving from water and vinyl chloride.

Due to the common use of Wavin products, the name has become genericised in some parts of Ireland to refer to any manufacturer of orange-coloured drainpipes.

[citation needed] The company operates in three locations in Ireland, with the main manufacturing and distribution plant in Balbriggan, North County Dublin, and additional offices in Lisburn and Cork .

Products for the European market include the smartFIX push-fit fitting, the Sentio heating and cooling controls, Tegra manholes and inspection chambers and the SiTech+ low noise in-house soil and waste drainage system.
