ILF for WASH: Social Impact Incentives (SIINC) - Aqua for All

Premium payments for additional impact achieved

Social Impact Incentives for water and sanitation enterprises



Social Impact Incentives (SIINC) are part of the suite of Impact-Linked Finance instruments offered by the Impact-Linked Fund for WASH programme. SIINC have been developed by Roots of Impact in collaboration with the Swiss Agency for Development and Cooperation (SDC).

SIINC reward 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.).

Using SIINC in the water and sanitation sector was successfully piloted in the Social Impact Incentives for WASH (SIINC for WASH) programme. Since 2020, SIINC for WASH has supported aQystaATEC, and KWSH.
