Project Management Consultancy – Bhatar STP Augmentation under AMRUT Mission
We were appointed as Project Management Consultants (PMC) for the augmentation of the existing 162 MLD Sewage Treatment Plant at Bhatar, enhancing its capacity to 277 MLD. The project is being executed under the AMRUT Mission to meet future urban wastewater treatment needs, incorporating advanced tertiary treatment standards.
Scope of Work:
- Detailed Project Report (DPR) Preparation: Comprehensive DPR including design, BOQ, cost estimates, and planning for a 115 MLD additional STP capacity.
- PMC for Field Execution: On-site supervision and management for design, construction, erection, testing, and commissioning of new 115 MLD treatment systems.
- Advanced Treatment Technologies: Implementation of BNR (Biological Nutrient Removal) and BPR (Biological Phosphorus Removal) for tertiary-level effluent quality.
- PLC–SCADA Integration: Real-time monitoring and performance diagnostics through SCADA systems linked to Surat Municipal Corporation’s central control room.
- O&M Framework: Post-commissioning operation and maintenance support for a period of 10 years.
Key Project Metrics:
- Existing Capacity: 162 MLD
- New Capacity Addition: 115 MLD
- Total Capacity Post-Augmentation: 277 MLD
- Technology Used: SBR, UV Disinfection, Sludge Handling Systems
- SCADA Monitoring: Centralized performance analytics
- Execution Status: 95% physical progress completed
Treatment Performance Parameters – Bhatar STP (Post-Augmentation)
- BOD: Less than 10 mg/l
(Removes over 96% of organic pollutants) - COD: Less than 50 mg/l
(Ensures chemical pollutant load is minimized) - TSS (Total Suspended Solids): Less than 10 mg/l
(Crystal-clear discharge quality) - Total Nitrogen: Less than 10 mg/l
(Compliant with Biological Nutrient Removal standards) - Total Phosphorus: Less than 2 mg/l
(Meets Biological Phosphate Removal requirements) - Fecal Coliform: Less than 100 MPN/100ml
(Safe for reuse or surface discharge under CPCB norms) - pH Range: 6.5 – 9.0
(Maintains biological stability of treated effluent) - Ammonical Nitrogen: Less than 5 mg/l
(Reduces toxicity for aquatic life and supports reuse)
Impact:
The Bhatar STP augmentation addresses future sewage treatment demands of Surat’s growing population while ensuring effluent quality meets CPCB norms. The integration of tertiary treatment, UV disinfection, and nutrient removal supports sustainable water management and reuse. The deployment of SCADA automation enables smarter operations with centralized performance monitoring, making this project a benchmark in urban wastewater infrastructure under the AMRUT Mission.
