How can nature help billions of people access sanitation and improved water quality across the globe? How can these sanitation goals contribute to benefiting nature?

There are 2.4 billion people living without sufficient sanitation to separate them from their biological waste. For another 2.1 billion, wastewater drains directly into surface waters. Despite improvements over past decades, unsafe management of fecal waste and wastewater still presents a major risk to public health and the environment. Natural solutions including constructed and natural wetlands, wastewater treatment ponds, and green roofs can be part of wastewater treatment systems to support the removal of wastewater contaminants such as bacteria, heavy metals and high levels of nutrients.


OUR APPROACH: This working group is developing an evidence-based guidance document which assesses both the technical feasibility and practicality of placing effective nature-based sanitation solutions in diverse local and cultural contexts. Their aim is to provide information which can inform investment and resource use in operation and maintenance of sanitation services which serves both human and ecosystem health.

This team is made possible in part by the generous support and engagement of the Bridge Collaborative, uniting experts in health, development and the environment to create the evidence and opportunity to solve big problems for people and the world we share.

Team Critical Challenge: Water and Nature
  • Understand how, where and when wastewater utilities and their regulators can implement nature-based sanitation solutions into wastewater treatment facilities while also providing benefits to nature and encouraging biodiversity.
  • Create interactive, publicly available guidance which consolidates information from across a variety of applied cases with scientific evidence that will inspire and influence sanitation providers and regulators to design and integrate wastewater treatment facilities with ecosystems in a way that benefits ecological and human health.
