The Nairobi City Water and Sewerage Company loses over Sh1 billion annually due to water theft, faulty meters, billing errors and illegal connections, a report has revealed.

The report by the Nairobi County Assembly Public Investments Committee revealed that the urban water firm is losing a whopping Sh1 billion in non-revenue water – water which cannot be unaccounted for.

The report also showed that the firm lost over Sh152 million in 2017 as a result of billing errors, underpayments and meter tampering by customers.

According to the report, Nairobi Water billed only 112,787,608 cubic meters of water out of the 181,363,932 cubic metres of water the firm produced in the 2016/17 fiscal year.

Thus, the company only earned Sh5.1 billion from all the water produced with the non-revenue water, which accounted for 38 percent, being over and above the allowable 25 percent in accordance with Water Services Regulatory Board guidelines.
