INWERT INSTITUTE for biological drinking water quality, Haltern am See, Germany.
The INWERT Institute is an association of Science - Technology - Drinking water network services with the aim to support water suppliers in achieving and maintaining a biologically stable drinking water supply. Drinking water distribution systems are difficult to access and require a complex approach to analyzing and assessing the presence of pipe network inhabitants, including microbes, but also larger organisms such as water lice, water snails and mosquito larvae.
The focus of the INWERT Institute's activities is the implementation of the German DVGW worksheet W 271, which sets standards for water suppliers. Another focus is the provision of advice and support in the risk assessment of the presence of small animals in drinking water systems in accordance with the amended German Drinking Water Ordinance (2023).
