Aged, sedimented pipelines hit water-carrying capacity in Kochi

French engineering firm SUEZ has discovered substantial pipe deterioration in the Kochi Corporation's water distribution network, according to studies conducted in the region. The research, commissioned by Kerala Water Authority (KWA), revealed significant sediment deposits within the aging pipeline infrastructure, particularly in Kaloor and Karuvelipady neighborhoods, limiting water flow.

Several pipelines situated beneath the backwaters have been identified as contamination sources and are slated for replacement. The French company, which assumed responsibility for water distribution operations in Kochi last year, has been carrying out assessments as part of its contract with KWA. The ₹1,141.28-crore project, funded by the Asian Development Bank, aims to optimize water distribution in the city.

The firm's survey also revealed that the condition of asbestos and cast iron pipelines is poor, with leakages observed in PVC pipes due to damage in certain areas. SUEZ officials stated that the survey results are preliminary, and a comprehensive evaluation will only be available after the completion of all assessments. KWA anticipates receiving the network design from SUEZ by November 15, following which implementation and construction will commence in the coming year.

Meanwhile, non-destructive testing of KWA's reservoirs, pump houses, and other infrastructure is also underway, with testing of reservoirs at Thammanam, Elamkulam, Fort Kochi, and Mattancherry already completed.
