An arm of the C40 Knowledge Hub that offers guidance to support cities in becoming resilient to flooding. Members of the network do this by identifying, mapping, planning, and implementing water management projects. Networking, governance, measuring, and collaboration play a central role. Adaptation strategies for water security and urban heating also feature.

SIWI is a not-for-profit institute and global change-making organisation with a focus on tighter governance. They seek to define a new relationship with water for more equitable, resilient, and prosperous places. You’ll find a wealth of information and policy guidance here, with expertise in developing nations. SIWI also organises World Water Week.

It's all part of the nexus! Water and energy converge: the power of water can be used to create energy; some energy sources need water for cooling; water supply itself depends on energy. The IEA seeks ways to manage increasing resource demand within geopolitical confines and to support cities via research, technology, and analysis to view water-energy through renewable and recycling prisms.

IWMI is a leading international research-for-development (R4D) organisation that generates solutions based on data and science. It scales them up in cooperation with stakeholders, from farmers to water managers. IWMI's initiatives contribute to development and address "water and land management challenges faced by poor communities in developing countries" to create a fairer distribution of resources and to enhance sustainability.

UN-Water is a ‘coordination mechanism’ designed to tackle Sustainable Development Goal 6: clean water and sanitation. It brings together the major players addressing water-based problems throughout multiple UN entities and partner organisations to inform policy, support monitoring and reporting, and build knowledge that inspires stakeholders to act. In 2022, they added a Sanitation Workers Knowledge and Learning Hub.

A non-profit with a mission to educate and inform populations about water resources, the IWRA aims to create interdisciplinary and international cooperation to drive urban water sustainability. They strongly influence decision-making by helping stakeholders understand the many touch points, influences, and challenges of water in our cities – from stormwater runoff to policy.

Delivering water and sanitation services to the urban poor based on the understanding that water utilities and infrastructure do not meet the people's needs or commercial requirements in the developing world.

Forging solutions for water scarcity and quality via a network of experts from the USA, Europe, and the Middle East. Taking a finance, business strategy, and technological approach, Water Foundry offers advice for long-term sustainability and innovative leadership support.

Professionals from across the water and sanitation sectors come together under the umbrella of the IWA. Researchers and scientists, utilities and tech companies involved with water management contribute to a knowledge base and professional network pushing for more equitable and robustly managed water resources. The IWA gathers representation from more than 140 countries.

India's WASH Institute aims to coordinate knowledge "between the community and service providers through education and training" in order to advance "planning, implementation, operation and management of water, sanitation, hygiene and environmental programmes". Their focus is on low-cost, high-impact solutions tried and tested on the ground with partners. These include strategies and capacity building that especially support vulnerable urban populations.

As a human-capital investor looking at future-proofing to mitigate cities' problems to come, EJWP (AKA H20-people) promotes skills and solution focussed growth for young water professionals. The programmes challenge and train participants during hands-on projects, extending their networks, capacity to collaborate, and knowledge of implementing and managing nature-based and technical solutions.
