The ZDHC Gateway – Wastewater Module is a web-based platform used by the global textile, apparel and footwear industry. Released in July 2017, it is designed to share verified wastewater and sludge test data, based on tests conducted by ZDHC Accepted Laboratories, and in accordance with the ZDHC Wastewater Guidelines. It offers manufacturing facilities an easy way to share data with their customers and drive their environmental performance. It also significantly reduces the amount of unnecessary testing, meaning resources can instead be used to improve wastewater treatment and the quality of effluents.


The ZDHC Wastewater Guidelines

Together with leading brands, governments and other multi-stakeholder organisations, ZDHC created the most comprehensive, unified guidelines for wet processing facilities across the entire value chain - the ZDHC Wastewater Guidelines. These guidelines, which go beyond regulatory compliance, help to ensure the discharge of treated wastewater does not adversely affect the environment and surrounding communities.
