Sewage & Effluent Treatment Plant in Riyadh
Tigreen designs, pre-builds, and installs compact, modular STP and ETP wastewater treatment plants for apartments, factories, tech parks, and hotels in Riyadh. NCEC compliant. Fits in 1 car parking space.
Meeting NCEC Norms in Riyadh with Pre-Built Systems
Wastewater discharge norms defined by the National Center for Environmental Compliance (Saudi Arabia) (NCEC) require robust, reliable sewage treatment plants (STP) and effluent treatment plants (ETP). For facilities in Riyadh, 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 Riyadh 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. NCEC 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 | NCEC Max Limit | Tigreen Guaranteed Output |
|---|---|---|---|
| pH Value | pH | 6.0 - 8.5 | 7.0 - 7.5 |
| Biological Oxygen Demand (BOD) | mg/L | < 10 | < 4 |
| Chemical Oxygen Demand (COD) | mg/L | < 50 | < 15 |
| Total Suspended Solids (TSS) | mg/L | < 10 | < 1.5 |
