Marginalized Communities

UNEP has implemented wastewater treatment projects in marginalized communities, improving sanitation and protecting marine and freshwater ecosystems. 

Decentralized Wastewater Treatment Systems (DEWATS) play a crucial role in addressing wastewater management and sanitation challenges in marginalized communities.

Wastewater and sanitation infrastructure are essential for public health and environmental protection.  

The following initiatives highlight collaborative efforts in enhancing wastewater treatment and sanitation practices:  

The Sabah project in Malaysia, led by UNEP and UN-Habitat in partnership with Action Caring Team (ACT) aims to improve wastewater, nutrient management, and sanitation for marginalized communities. In Lok Urai, where approximately 50,000 residents discharge untreated wastewater into water bodies, the initiative equips locals and policymakers with tools to address pollution.  In Tanzania, UNEP partnered with Bremen Overseas Research and Development Association to disseminate guidelines on DEWATS. Developed by UNEP, BORDA, UN-Habitat, and Tanzania's Ministry of Water, in 2018 these guidelines were translated into Swahili, providing knowledge for planning and implementing DEWATS. 

These projects contribute to SDGs 6 (Water and Sanitation for All) and 14 (Life Below Water)
