The Kenya water supply and sanitation (WSS) sector has been on a long pathof facilitating commercial lending to Water Service Providers (WSPs). A keycomponent of this effort is the evolution of rating the credit risk of WSPs for locallenders. However, the trade-off in credit rating WSPs is to provide the best creditanalysis to help lenders assess the creditworthiness of WSPs, yet have a systemthat is simple and affordable enough to replicate on an annual basis. To solve this trade-off, the Water Services Regulatory Board (WASREB)and the Water and Sanitation Program of the World Bank have created aCreditworthiness Index for the WSPs in Kenya. In lieu of performing a fullshadow rating analysis, which is much more thorough yet also more time-consumingand costly, the Creditworthiness Index provides a simplified snapshotof the financial and operational performance of WSPs.
