SIINC for WASH: Innovative finance for water and sanitation - Aqua for All

Accelerating scale with greater impact

SIINC for WASH for water and sanitation enterprises

Social Impact Incentives for Water, Sanitation and Hygiene

The Social Impact Incentives for Water, Sanitation and Hygiene (SIINC for WASH) is an innovative, results-based financing programme co-designed and implemented by Roots of Impact and Aqua for All. It rewards selected water and sanitation enterprises with time-limited payments for achieving additional social and environmental impact. This additional revenue enables the enterprises to improve their profitability and attract investments. It therefore accelerates their scaling efforts and  supports them in reaching self-sustainability. Selected water and sanitation enterprises must raise repayable investment(s) (equity, debt or mezzanine, etc.).

While impact-linked finance is not completely new in the water and sanitation sector, it has barely supported social enterprises and market-based approaches, has not necessarily incentivised sustainability and has rarely focused on leveraging private investments.


A comprehensive impact-linked finance programme  

SIINC for WASH showed the great potential for catalysing finance for water and sanitation enterprises. It also revealed the enterprises’ need for capacity building. Some shortlisted enterprises would strongly benefit from pre-SIINC support to be considered for the pipeline. Based on this experience, there are plans to enhance the SIINC for WASH programme to include pre-SIINC support, technical assistance and learnings exchange to increase its outreach and impact.

If you are interested in investing in SIINC for WASH or in knowing more about this innovative financing programme, please contact Aqua for All.

What is SIINC?

SIINC for WASH is based on the SIINC funding instrument developed by Roots of Impact in collaboration with the Swiss Agency for Development and Cooperation (SDC). SIINC has been already used in a variety of sectors, such as employment and education, health, agriculture and clean energy, in different geographical areas.

SIINC for WASH in practice

In August 2020, Aqua for All and Roots of Impact launched the first SIINC for WASH’s call for applications. It attracted 140 applications from 33 countries across Asia, Sub-Saharan Africa, and the Middle East and North Africa (MENA) region. Even though the initial plan was to finance two cases, four promising enterprises were selected. Aqua for All has allocated €1.2 million to fund the four enterprises for a period up to 36 months.
