NYEWASCO Sewage Treatment Plant - Nyeri, Kenya Wastewater Facility

NYEWASCO Sewage Treatment Plant is a municipal wastewater facility located in Nyeri, Kenya, operated by the Nyeri Water and Sanitation Company (NYEWASCO). The plant serves the local population and is part of the region's sanitation infrastructure. As an operational facility, it plays a key role in treating wastewater from the surrounding urban area. The plant operates under Kenya's regulatory framework for wastewater management, which is guided by the National Environment Management Authority (NEMA) and the Water Services Regulatory Board (WASREB). For agglomerations of this scale, secondary treatment is typically required to meet national discharge standards. The plant's treatment process and capacity are aligned with local environmental regulations. Treated effluent from the plant is discharged into the Chania River, a tributary of the Tana River, which flows into the Indian Ocean. The Tana River basin supports diverse aquatic life and is an important water resource for agriculture and communities downstream. The plant's operations help protect this vital ecosystem from untreated wastewater pollution.

The plant discharges into the Chania River, part of the Tana River basin, which ultimately drains into the Indian Ocean. The Tana River is Kenya's longest river and supports a rich diversity of fish and bird species, as well as providing water for irrigation and hydropower. Protecting this watershed from untreated sewage is critical for maintaining water quality and ecosystem health downstream.
