Water Services Regulatory Board monitors water services firms’ work and publishes results in its annual Impact Report.
The board said comparative competition through ranking of utility performance is a key tool for driving utility efficiency.
Where do scores come from?
Water coverage – percentage of people served with water services divided by people in service area. It should be more than 90%.
Drinking water quality – takes into account drinking water quality, residual chlorine and bacteriological quality. Should be more than 95%.
Hours of supply – average number of hours water services are provided per day of all the zones served by a firm. For population of more than 100,000 it should be 21-24 hours; for population less than 100,000 it is 17-24 hours.
Personnel expenditure as a percentage of operation and maintenance costs – percentage of sum of personnel expenditure during reporting period divided by total operation and maintenance costs. For large and very large firms, it should be less than 20%; medium firms, less than 30%; small firms less than 40%.
Operation and maintenance cost coverage – percentage of total operating revenue divided by total operating expenditure. It should be at least 150%.
Revenue collection efficiency – percentage of total revenue collected divided by total billing. It should be more than 95%.
Non-revenue water – percentage of water losses from illegal connection, meter reading inaccuracies and leakages divided by volume of water produced. It should be less than 20%.
Metering ratio – percentage of total number of active metered connections divided by total number of active connections. It should be 100%.
Staff productivity – total number of staff in a firm divided by total number of active connections plus number of sewer connections. For large and very large firms, it should be less than 5; medium and small firms in less than 3 towns, less than 7; medium and small firms in three or more towns, less than 9.

Assessment of water firms’ performance in 2020
The board’s outgoing Chief Executive Officer Robert Gakubia said there was general decline in performance.
He said only three indicators recorded improvement while five declined and one stagnated.
“This, is a departure from the previous reporting period where improved performance was recorded in four indicators, a drop in three and stagnation in two,” Mr Gakubia said.
Water coverage for areas served by regulated firms declined from 59% in 2019 to 57% in 2020. The board attributed this to population growth surpassing growth in access.
Sewer coverage declined from 17% recorded in 2018/19 to 15% in the current period.
Non-revenue water increased from 43% to 47%.
National Water Services Strategy targets non-revenue water of less than 30%. Vision 2030’s non-revenue water goal less than 25%.
“The indicator has not recorded significant improvement despite the commercialisation of services,” Mr Gakubia said.
Impact Report 2020 says more focus must be put on non-revenue water reduction to improve sustainability of water firms.
“The continued decline of this indicator in the last two years despite improvement in other KPIs [key performance indicators] does not give comfort that the current level of service can be sustained going forward,” the report says.
