Making Blended Finance Work for Water and Sanitation

Unlocking Commercial Finance for SDG 6

Published on August 26, 2019

Investments in water and sanitation are a prerequisite to deliver on the Sustainable Development Goals (SDGs), in particular on SDG 6 ensuring availability and sustainable management of water and sanitation for all. Blended finance can play an important role in strategically investing development finance to mobilise additional commercial finance needed to fill the current investment gaps. Thus far, however, blended finance has not reached scale in the water and sanitation sector. A greater evidence base is needed to better understand the current applications as well as the potential of blended models in the water and sanitation sector. This publication takes a commercial investment perspective and provides insights into three subsectors: (1) water and sanitation utilities, (2) small-scale off-grid sanitation and (3) multi-purpose water infrastructure and landscape-based approaches. The publication draws out recommendations for policy makers and practitioners to apply and scale innovative blended finance approaches where most appropriate.

On Monday 9 September, our team of experts discussed the key findings of this report during a live webinar.

Where has blended finance worked so far? How can this experience be adapted to new contexts and investment types? How can well-designed policies strengthen the enabling environment to crowd-in commercial capital and strengthen the financing systems upon which water-related investments rely?

Water-related investments are a prerequisite to deliver on the Sustainable Development Goals, yet financing persistently falls well short of investment needs. This report shows how blended finance can play an important role to deploy development finance more strategically to mobilise additional commercial finance.
