Two water companies in Nyeri County lost more than Sh103 million worth of treated water through leakages and illegal connections.
In his latest report for the financial year 2016-2017, Auditor General Edward Ouko warns that the rate of unaccountable water could affect the sustainability of the utility firms.
Mathira Water and Sanitation Company recorded the highest level of non-revenue water at 53 per cent, resulting in an estimated loss of close to Sh77 million.
This is way above the 25 per cent allowable loss in accordance to the Water Services Regulatory Board guidelines. The water is lost through leaks, burst pipes, theft or meter inaccuracies.
During the year under review, the company produced 3.1 cubic metres of water with only 1.1 cubic meters being billed to customers.
This means that more than half of drinkable water was lost.
“The significant level of non-revenue water may negatively impact the company’s profitability and its long term sustainability,” Mr Ouko warned.
Tetu Aberdare Water and Sanitation Company has also been put on the spot over failure to bring down the quantity of lost water.
According to the auditor general, the company produced 3.7 million cubic metres of water during the year under review but only 2.3 million cubic metres were billed.
