CS Deborah Barasa Leads Major Crackdown on Nairobi River Pollution

The government has intensified its fight against environmental degradation following a high-level inspection of the Nairobi River system led by Environment, Climate Change and Forestry Cabinet Secretary Dr. Deborah Barasa.

The inspection, conducted alongside Dr. Mamo B. Mamo, signaled a major escalation in efforts to curb industrial pollution and restore the heavily contaminated river system.

During the tour of several industrial sites within Nairobi, the CS assessed compliance measures put in place by industries to prevent the discharge of untreated effluents into the city’s waterways.

Dr. Barasa declared that the era of “pollute now, pay later” had come to an end, warning that environmental compliance is no longer optional but a legal and moral obligation for all industries operating in the country.

“The condition of the Nairobi River is no longer just an environmental concern. It is now a measurable crisis that directly threatens ecosystems, livelihoods and public health,” she said.

According to findings highlighted during the inspection, the Nairobi River system is currently burdened by industrial chemicals, untreated sewage from informal settlements and hazardous stormwater runoff.

The CS noted that more than 70 per cent of wastewater generated within Nairobi is discharged into the environment without treatment, worsening pollution levels and exposing residents to significant health risks.

In response to the growing crisis, Dr. Barasa directed the National Environment Management Authority to move from routine monitoring to strict and uncompromising enforcement against polluters.

The directive targets industries and facilities accused of allowing environmental negligence to persist for years while contributing to the degradation of the river ecosystem.

As part of the crackdown, the CS announced a “zero tolerance” policy against facilities operating without functional effluent treatment plants or those whose treatment systems fail to meet national discharge standards.

Under the new measures, non-compliant facilities risk immediate sanctions, closure orders and legal action.

Dr. Barasa said the government is determined to restore the Nairobi River and ensure industries adopt sustainable waste management practices that protect the environment and public health.

Environmental stakeholders have welcomed the move, saying tougher enforcement is necessary to reverse years of pollution and safeguard water resources for future generations.

The Nairobi River has for years faced severe pollution due to rapid urbanisation, weak waste management systems and illegal discharge of industrial waste, prompting growing calls for urgent government intervention.
