# SUEZ Completes Preliminary Water Network Audits for Kochi Infrastructure Upgrade

French utility firm SUEZ has finished a door-to-door survey of 100,000 households and topographical mapping to overhaul Kochi’s aging water supply system. The project, backed by the Asian Development Bank, aims to address chronic supply shortages and infrastructure degradation.

## Key takeaways

- SUEZ has surveyed 100,000 households in Kochi to map water demand and identify existing supply issues.
- The Kerala Water Authority project is funded by a ₹1,141.28-crore Asian Development Bank investment.
- Technical audits include pipe camera inspections, flow meter monitoring, and non-destructive testing of storage tanks.
- Design for the new pipeline network will begin in completed zones while the remaining 1.25 lakh households are surveyed.

## What Happened

French engineering firm SUEZ has finalized a door-to-door consumer survey covering over one lakh households within the Kochi Corporation limits. This data collection effort is part of a broader technical audit to identify resident complaints, calculate current water consumption, and project future demand. Alongside the consumer data, the firm completed topographical and walkthrough surveys of the existing Kerala Water Authority (KWA) pipeline network.

Operations have expanded beyond data collection to include structural and technical diagnostics. SUEZ is currently conducting flow measurements using specialized meters to track water distribution volumes. Additionally, the firm is executing condition assessments by inserting cameras into physical pipe segments to evaluate internal degradation. For static infrastructure, such as water tanks in Thammanam and Elamkulam, the firm is employing non-destructive testing methods, including pulse velocity, rebound hammer, and carbonation tests, alongside chemical analysis.

## Background

The initiative is part of a ₹1,141.28-crore project funded by the Asian Development Bank. SUEZ assumed responsibility for the operation and maintenance of the KWA pipeline network in the Kochi Corporation earlier in 2026. While the initial contract anticipated 1.5 lakh connections, updated estimates suggest the project area contains approximately 2.25 lakh households, presenting a larger technical scope than originally planned.

## What Happens Next

The consumer survey is expected to conclude in approximately two months to reach the remaining households. However, SUEZ has received authorization to begin the network design phase in specific zones where data collection is already complete. The final design of the new pipeline network will be dictated by the integrated findings of the flow assessments, structural tests, and consumer demand data. This evidence-based approach intends to ensure the new infrastructure can sustain the actual population density of the Corporation.
