How long does it take to procure and commission an ETP in India?

For a medium-sized industrial ETP (50–500 KLD), a realistic timeline from RFP issue to commissioning is 9–18 months: 1–2 months for RFP, evaluation, and vendor selection; 2–4 months for detailed engineering and approvals; 3–6 months for equipment fabrication and civil construction; 1–2 months for installation and commissioning; and 1–3 months for performance testing. Shorter timelines than this should be examined critically.

Should civil works be included in the ETP tender or tendered separately?

For most industrial buyers, a turnkey tender — including civil works, equipment, installation, and commissioning — is the preferred approach. It places a single point of responsibility with the ETP vendor for system performance, eliminating the interface risk between civil contractor and equipment supplier. Separate civil contracts are appropriate when you have an in-house civil team or an existing civil contractor relationship and want to manage civil and equipment procurement independently.

What is a performance guarantee test and how should it be structured?

A performance test is a structured trial of the commissioned system under actual operating conditions, with monitored inlet and outlet sampling over a defined period (typically 30–60 days) to verify that outlet quality meets the guaranteed parameters. Samples should be analysed by a NABL-accredited third-party laboratory. The test protocol — including trigger conditions, sampling frequency, and remediation obligations — should be fully specified in the contract before signing.
