Water Unite


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


Currently in its pilot phase, Wellers Impact and Water Unite have partnered to create the Water Unite Pilot Investment Vehicle (WUPIV).

WUPIVs provide risk-tolerant capital to Small and Medium Enterprises (SMEs) in the water, sanitation and plastics recycling sectors who are contributing to addressing the following three global challenges:

2 billion

people globally who live without sanitation facilities.

300 million

tonnes of plastic produced annually, of which less than 10% is recycled.

785 million

people globally who live without access to safe water.

WUPIVs address the funding gaps in parts of the financing ecosystem not met through charitable foundations, microfinance institutions, commercial banks and/or formal capital markets. We are catalytic, bringing together new private sector investors, retailers and other existing participants in the water, sanitation and plastics recycling sectors.

Structure of the Investment Vehicle

The WUPIV 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 WUPIV targets to deliver an attractive financial return to Investor Partners.

WUPIV has a significant leveraging effect: attracting external expertise and commercial capital into achieving social impact.

The diagram below depicts the innovative financial structure for WUPIV:


Currently, in a pilot phase, WUPIV’s objectives are to validate the following:

  • Ability of WUPIV to achieve social impact and generate early positive financial returns in the water, sanitation and plastics recycling sector

  • Amplified contribution to the UN SDGs due to leveraging effect of the proposed structure

  • Demonstrate availability of a pipeline of diverse SMEs that fit the defined investment strategies

Wellers Impact is continuing to seek interested Investor Partners who have aligned impact and financial objectives with WUPIV. Please contact us to learn more.
