Sewage & Effluent Treatment Plant in Nairobi
Tigreen designs, pre-builds, and installs compact, modular STP and ETP wastewater treatment plants for apartments, factories, tech parks, and hotels in Nairobi. NEMA compliant. Fits in 1 car parking space.
Meeting NEMA Norms in Nairobi with Pre-Built Systems
Wastewater discharge norms defined by the National Environment Management Authority (Kenya) (NEMA) require robust, reliable sewage treatment plants (STP) and effluent treatment plants (ETP). For facilities in Nairobi, conventional civil construction takes months, disrupts site logistics, and requires massive space footprints.
Tigreen offers a pre-engineered, factory-tested alternative. Our modular packaged units are manufactured at our state-of-the-art facility and shipped directly to your location in Nairobi as a complete plug-and-play system. No deep excavation, no permanent concrete pools, and complete commissioning in just 1 week.
Through our proprietary radical microbubble flotation technology, we guarantee up to 85% water recovery. The tertiary treated water is perfectly safe and compliant for reuse in landscape irrigation, flushing, and cooling towers, significantly cutting your fresh water tanker reliance.

Guaranteed Output Parameters vs. NEMA Limits
Tigreen's advanced flotation and multi-barrier filtration system delivers treated water that consistently performs far better than standard local board thresholds.
| Wastewater Parameter | Unit | NEMA Max Limit | Tigreen Guaranteed Output |
|---|---|---|---|
| pH Value | pH | 6.5 - 8.5 | 7.0 - 7.6 |
| Biological Oxygen Demand (BOD) | mg/L | < 10 | < 5 |
| Chemical Oxygen Demand (COD) | mg/L | < 30 | < 15 |
| Total Suspended Solids (TSS) | mg/L | < 10 | < 2 |
