The document summarizes Jamaica's wastewater treatment plant (WWTP) rehabilitation program funded through a public-private partnership. The program involves upgrading 14 pilot WWTPs with $3 million in grants each from GEF/CReW and a $10 million loan from a commercial bank to the National Water Commission (NWC). The loan is guaranteed and will be repaid through projected revenue increases (the "K-Factor") from improved wastewater services. Several WWTP projects have been completed or are underway using this financing model, which addresses issues around commercial loan terms and timelines for realizing project benefits.
