SUEZ surveys find deteriorating water pipes in Kochi

SUEZ surveys have identified ageing pipes and internal deposits restricting water flow in parts of Kochi. The findings remain preliminary, The Hindu reported, citing sources at the company and Kerala Water Authority (KWA).

Problems were particularly evident in Kaloor and Karuvelipady. A SUEZ source said sand, mud and other deposits reduced internal pipe diameter and carrying capacity. Surveys also found deteriorating asbestos and cast-iron pipes, along with leaks in some PVC sections.

Pipelines running beneath backwaters in Karuvelipady, Fort Kochi and Mattancherry were identified as contamination sources and are earmarked for replacement or relocation. A full assessment will follow completion of the surveys.

KWA agreed a water distribution improvement contract with SUEZ last year. The project costs 1,141.28 crore rupees and is financed by the Asian Development Bank. SUEZ separately confirms its contract to upgrade, operate and maintain the network.

The company has surveyed more than 220,000 households. A KWA source said the remaining consumer survey was expected to finish in about 15 days. Network designs are expected by November 15 for authority review, with construction planned to begin next year.

Non-destructive testing is also underway at reservoirs, pumping facilities and other infrastructure. Reservoir tests in Thammanam, Elamkulam, Fort Kochi and Mattancherry have finished, but their results are still awaited.
