A report based on national polling by the International Institute for Sustainable Development (IISD) and Nanos Research detailing Canadian public support for water infrastructure investment and the prevalence of water-related challenges.

A July 2026 report by the International Institute for Sustainable Development (IISD) presents findings from a national poll of 2,219 Canadians regarding water infrastructure. The results indicate a high public demand for urgent government action on water infrastructure and strong support for the implementation of natural infrastructure to address deficits and improve resilience.

This Request for Proposal (RFP), issued by the GreenCape Sector Development Agency on 29 August 2025, seeks a Professional Service Provider (PSP) to conduct project preparation activities for three infrastructure projects in the Saldanha Bay Municipality. The work is part of the Sustainable Infrastructure Development and Financial Facility (SIDAFF) Programme, which is funded by international donors including the Swiss State Secretariat for Economic Affairs (SECO) and Impact Fund Denmark (IFD). The PSP will guide projects from initiation through to documentation and procurement, ensuring compliance with both South African law and international standards, specifically the International Finance Corporation's (IFC) Performance Standards and World Bank Environmental and Social Standards.

This executive summary by the International Institute for Sustainable Development (IISD) examines the role of natural infrastructure in addressing Canada's water infrastructure gap. It assesses six federal funding programs against 14 enabling criteria, finding that while most allow natural infrastructure, actual funding remains disproportionately low. The document provides recommendations to integrate natural infrastructure into federal frameworks, increase funding for proactive adaptation, and build local government capacity.

This executive summary outlines pathways to increase private investment in natural infrastructure within the Canadian Prairies to address a growing water-related infrastructure funding gap.

The Itanya Africa Group implemented a project in lower eastern Kenya focused on regenerative agricultural practices and financial tools to support female smallholder farmers, aiming to improve biodiversity, nutrition, soil health, and economic output.

This technical brief presents findings from a 2023 longitudinal study assessing five public good climate investments in water infrastructure in Garissa County, Kenya. These investments were implemented between 2015 and 2016 via the County Climate Change Fund (CCCF) mechanism. The study evaluates the technical sustainability and governance of these assets eight years after implementation, highlighting significant challenges regarding funding for maintenance, technical capacity, and institutional engagement.

This technical brief presents the findings of a 2023 longitudinal study assessing nine public good climate investments in water infrastructure in Isiolo County, Kenya. These investments, implemented between 2014 and 2016 via the County Climate Change Fund (CCCF), were evaluated for their functionality and governance nine years after implementation to provide insights into the sustainability of locally-led adaptation (LLA) projects.

This technical brief presents the findings of a 2023 longitudinal study assessing 13 public good climate investments in water infrastructure in Makueni County, Kenya. These investments were originally implemented between 2016 and 2017 via the County Climate Change Fund (CCCF) mechanism. The study evaluated the technical sustainability, governance, and functionality of the sites seven years after implementation to provide insights into locally-led adaptation (LLA) and climate finance flows.

A 2023 study of 23 climate-funded water investments in Wajir County, Kenya, found that boreholes are significantly more resilient and functional than water pans, which are highly susceptible to seasonal droughts and floods. While community-led planning increased ownership and sustainability, the study identified critical gaps in technical maintenance skills, spare part availability, and the integration of climate information during the design phase. The brief recommends improving climate information services, strengthening technical capacity for site committees, and allocating specific funds for ongoing monitoring and evaluation.

This executive summary outlines the proceedings of the 2022 Forum on Natural Infrastructure Performance and Metrics hosted by the International Institute for Sustainable Development in Winnipeg, Manitoba. The event focused on developing a stronger business case for water-related natural infrastructure (NI) across Canada's Prairies by addressing challenges in performance metrics, data collection, and economic visibility.

This fact sheet by the International Institute for Sustainable Development describes the economic impact and growth potential of the natural infrastructure sector in the Canadian Prairies, with a specific focus on Saskatchewan. It defines natural infrastructure as a method of planning and working with nature to meet needs such as wastewater treatment, flood protection, and drinking water supply.

The Climate Adaptation Notes (CAN) is a proposed funding mechanism designed to increase private, commercial bank, and institutional investment in water and wastewater infrastructure projects across sub-Saharan Africa by combining short-term construction financing with long-term asset-based funding.

A case study on Climate Investor Two, a fund managed by a consortium including Climate Fund Managers and FMO to manage the EUR 160 million Dutch Fund for Climate and Development, focusing on water, oceans, and sanitation infrastructure in low- and lower middle-income countries.

This reference guide by GreenCape provides a strategic framework for water and wastewater businesses and investors seeking to enter or expand within the South African public water sector. It details the sector's governance structure, the legal requirements for public procurement, various contracting models, and strategies for forming partnerships and trialling new technologies.

The Water Infrastructure Criteria, published by the Climate Bonds Initiative in January 2021, provide a technical framework for certifying bonds that finance water-related assets. The criteria cover engineered, nature-based, and hybrid infrastructure used for water collection, storage, treatment, distribution, flood protection, and drought resilience. To achieve certification, assets must meet both mitigation requirements (reducing GHG emissions) and adaptation and resilience requirements (demonstrating robustness to climate change).

The Brighton Township Municipal Authority issued a USD 5.9 million green bond on August 13, 2020, to fund capital improvements for its water system.

The Milwaukee Metropolitan Sewerage District (MSSD) issued a USD 80 million green bond on April 30, 2020, to finance water and wastewater infrastructure, including water treatment, wastewater treatment, water distribution, and flood protection.

The South African Water Caucus (SAWC) submitted an urgent request to Minister Lindiwe Sisulu on 22 April 2020, demanding the provision of water tanks, reliable water supply, and sanitation packs for numerous communities lacking basic water access during the COVID-19 pandemic.

This fact sheet details a USD 196 million green bond issuance by the Narragansett Bay Commission Wastewater System on March 19, 2020, intended for the advance refunding of outstanding Wastewater System Revenue Bonds.
