The overall best performing utility for the eighth year in a row was Nyeri while the lowest ranked utilities were Olkejuado (third consecutive year) and Eldama Ravine. Water Services Regulatory Board said it is worrying that the two worst performing utilities recorded a score of zero in all nine key performance indicators.
Performance assessment and ranking of utilities is key in ensuring that water services are provided in an efficient and sustainable manner. Utilities continue to be assessed and ranked on the basis of nine key performance indicators.
These are water coverage, drinking water quality, hours of supply, non-revenue water reduction, and metering ratio. The others are staff productivity, revenue collection efficiency, operation and maintenance cost coverage and personnel expenditure as a percentage of operation and maintenance costs.
Operation and maintenance cost coverage is the extent to which a utility is able to meet its operation and maintenance costs from internally generated funds. Operation and maintenance coverage is critical to the performance of a utility as it is a first step towards full cost coverage. It ensures long term financial sustainability.
