Project Management Consultancy – Dindoli STP & TSTP Augmentation and Reuse System
We were appointed as Project Management Consultants (PMC) for the integrated augmentation of sewage and tertiary treated water systems in Dindoli, Surat. The scope included upgrading an existing sewage pumping station, expanding the capacity of the STP from 66 MLD to 167 MLD, and commissioning a 40 MLD Tertiary Sewage Treatment Plant (TSTP) to deliver industrial-grade water. The project was delivered under a 10-year Operation & Maintenance framework.
Scope of Work:
- Integrated Infrastructure Augmentation:
Design, erection, testing, and commissioning of:
a) Existing Sewage Pumping Station
b) 66 MLD STP augmentation to 167 MLD
c) New 40 MLD net output TSTP for reuse - Industrial Reuse Water Generation:
Commissioning of TSTP for production of high-quality tertiary treated water suitable for industrial use. - Operation & Maintenance:
Comprehensive O&M responsibility for 10 years, post-commissioning, for all project components. - PMC Responsibilities:
Preparation of technical designs, estimates, tender documents, quality control and project supervision throughout implementation.
Key Project Metrics:
- STP Capacity Augmentation: From 66 MLD to 167 MLD
- TSTP Output: 40 MLD industrial-grade water
- Water Reuse Objective: Treated water supplied for industrial consumption
Impact:
The Dindoli project marks a major milestone in Surat’s water reuse strategy. By converting treated wastewater into high-quality industrial-grade water, this project reduces dependency on freshwater sources and supports circular water economy goals. The STP capacity expansion ensures compliance with urban growth, while the high-performance TSTP meets CPCB norms for effluent discharge and reuse. This project is a benchmark for sustainable wastewater reuse under long-term PMC and O&M frameworks.
