Nairobi City Council Sewage Treatment Works - Major Wastewater Plant in Kenya's Capital

Nairobi City Council Sewage Treatment Works is a major wastewater treatment facility serving Nairobi, the capital and largest city of Kenya. The plant is located in the central highlands of the country and is part of the city's essential water and sanitation infrastructure. As a large urban treatment facility, it is expected to provide at least secondary treatment in line with Kenyan national standards and international best practices. The plant operates under the regulatory oversight of Kenya's Water Services Regulatory Board (WASREB) and the National Environment Management Authority (NEMA), which set discharge standards to protect public health and the environment. The treated effluent from the plant is discharged into the Nairobi River, which flows into the Athi River and eventually reaches the Indian Ocean. The plant's operation is critical for reducing pollution in the Athi River basin, which supports diverse aquatic life and provides water for downstream communities and agriculture.

The plant discharges into the Nairobi River, a tributary of the Athi River, which flows southeast through Kenya to the Indian Ocean. The Athi River basin supports a variety of ecosystems and is a vital water source for agriculture and wildlife. Effective treatment at this plant helps mitigate pollution impacts on downstream water quality and aquatic habitats.
