Water Utility Revenue Risk Assessment Tool

As part the Defining a Resilient Business Model for Water Utilities project, the EFC developed this tool to allow utilities and technical assistance providers to quickly determine the proportion of residential revenues from water sales that may be at risk of loss when residential customers change demand patterns.

Utilities often ask how much of their revenues are really and realistically at risk of loss if their customers lower their consumption.
