Wastewater Quality

Water efficiency is a critical aspect of sustainable and environmentally-conscious manufacturing. While there have been efforts to create regulations by individual governments, brands and even multi-brand consortia, there still exists no single industry-standard guideline that covers all discharge criteria. 

The ZDHC Programme is creating a new standard in wastewater discharge that goes beyond regulatory compliance to ensure wastewater discharge does not adversely affect the environment and surrounding communities. 

As a first step towards this, the programme published a literature review of current wastewater discharge standards applicable to the textile industry.This study established a baseline on which to develop a revised global industry guideline. 

The ZDHC Wastewater Guidelines set a unified expectation on wastewater quality for the entire textile and footwear industry and are available in English and Simplified Chinese.

ZDHC Wastewater Disclosure Portal

Preview of the tool.


The ZDHC Roadmap to Zero Programme, together with ADEC Innovations is currently developing an interactive Wastewater Disclosure Portal. This Portal is now in the beta testing pilot and we’re working together with stakeholders to improve the tool. 

It intends to provide the industry with an overview of the supply chain performance with respect to the conformance to the ZDHC Wastewater Guidelines.
