Water Unite

Water Unite Impact, managed by Wellers Impact, invests in water, sanitation and plastics recycling firms globally.


The Water Unite Impact (WUI) investment vehicle provides an opportunity to create a widespread impact that goes beyond typical WASH investments through our Water+ approach.

Wellers Impact partnered with Water Unite to create Water Unite Impact (WUI) and to develop the Water Unite Impact investment vehicle, enabling active investments in high impact “missing middle” entities.

WUI recognises and leverages critical global problems to create opportunities, supporting entrepreneurship and new technological advancements in and beyond the WASH (water, sanitation and hygiene) sector.

The WUI investment vehicle has adopted a “Water+” approach in order to address the WASH sector’s rapidly changing landscape.

Structure of the Investment Vehicle

The WUI investment vehicle has been structured using an innovative financial model to leverage greater private sector capital into the water, sanitation and plastics recycling sectors and to build long-term financial sustainability of its investees. It demonstrates a creative way of enabling each dollar of funding to support more than one organisation to generate social and environmental impact multiple times over.

The investment vehicle is structured using micro-levy contributions from international retailers to provide catalytic capital. This capital is used to take a higher risk-reward position, acting as a credit enhancement mechanism to leverage additional Senior Capital. The Senior Capital is protected by the Catalytic First Loss Tranche Capital, as they will rank higher in the pecking order in a default scenario. Through the portfolio of investments made, the investment vehicle targets to deliver an attractive financial return to Investor Partners.
