Sewage Treatment Plant (STP) Design
Municipal & Residential Sewage Treatment Engineering
- ✓ Safe Discharge
- ✓ Reuse Capable
- ✓ Low Odour Design
Service Overview
Our STP Design service delivers complete sewage treatment solutions for residential complexes, commercial buildings, municipalities, and industrial campuses. We design biological treatment systems — including activated sludge, SBR, MBR, and constructed wetlands — producing treated effluent suitable for safe discharge or reuse in irrigation and flushing. All designs comply with DoE and national environmental standards.
