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.
