Rietland has been designing and building constructed wetlands for wastewater treatment since 1994.
Dion van Oirschot, founder and still business owner, combined his technical background from Eindhoven University of Technology with his passion for the environment. Since the start of the company, several hundred systems have been designed and built in Belgium and the Netherlands. Initially, the emphasis was mainly on the treatment of domestic waste water of private homes in the non-sewered rural area and at ecological housing projects. In addition, various projects were carried out with the treatment of rinsing water from dairy farms. A number of projects have also been realized for Water Boards for the removal of nutrients (N and P) from surface water and drainage water. Thus we have gained a lot of experience with different types of reed beds, each with their specific strengths.
In particular, the vertical flow wetland, was further developed by Rietland into a robust, compact and efficient system for wastewater treatment. In 2009, this development reached a milestone in obtaining the BENOR quality mark. This made Rietland the first and only European company to date with a CE-certified reed bed in accordance with European standard EN 12566/3. Rietland also participated intensively in a number of educational projects at schools in Mechelen, Westmalle and Oudenbosch and in the Huizingen provincial domain.
From the side of the business community, the interest in treatment of wastewater with planted systems has been growing. Clients included Fluxys, Sibelco, Bebat, Antwerp Port Authority and Warsco Units.
To exchange knowledge and experience with other experts, Dion van Oirschot visited various international conferences of the IWA and WetPol and fruitful partnerships were established with Ingenieurbüro Blumberg (D) and Naturally Wallace Consulting (USA). Rietland started to focus attention as well to the treatment of industrial waste water and the dewatering of sludge. A new type of treatment wetland was also introduced: the aerated reed bed, which can handle larger loads at a lower surface requirement. A very noteworthy application of the aerated reed bed was realized on the Badboot, a floating swimming pool in Antwerp. In 2014, Rietland won the Project Innovation Award of the International Water Association in the category 'design' for this project.
In 2012, Rietland was one of the founding members of 'Global Wetland Technology', an association of specialists in the design and construction of constructed wetlands for the treatment of waste water and sludge (www.globalwettech.com). In the same year, cooperation started between Rietland and the Belgian company Innova Manure, a company specializing in reed beds for the treatment of the liquid fraction of pig manure. Rietland Agro was founded in 2015 to join forces within the agricultural sector.
Internationally, Rietland worked on projects in Dubai (UAE) and Jordan and participated in the HIGHWET project (EU - FP7) in collaboration with research partners Aimen (Sp.) And the University of Aarhus (Dk.). The other two participating SMEs were Kilian Water (Dk.) And Sedaqua (Sp.).
