International Greywater Association

The International Greywater Association (IGWA) is a global organization focused on promoting the sustainable management and reuse of greywater, which is wastewater generated from domestic activities like washing dishes or taking showers, but not from toilets. IGWA works to raise awareness, develop guidelines, and support best practices for greywater systems, helping communities save water and reduce environmental impact. By advocating for safe, efficient greywater use, the association aims to foster water conservation and improve resilience against water scarcity worldwide.
