India - Agriculture - Corrosion of Barrage Shutters, a big concern for farmers in Cauvery Delta Districts, Tamilnadu. Waste water released into the Cauvery has worsen the situation

Corrosion of Barrage Shutters, a big concern for farmers in Cauvery Delta Districts, Tamilnadu. Waste water released by the dying units into the Cauvery worsen the situation.


TRICHY: Farmers in delta districts are disappointed over the dry-Cauvery river. But the dryness has helped the public works department (PWD) to take up refurbishing rehabilitation works on corroded shutters of the barrage at Upper Anaicut (Mukkombu) in Trichy. The waste water containing chemicals released from dying units in Karur to the river is said to be one of the major reasons for corrosion.

The second phase of refurbishing works on 26 of the total 41 shutters on the barrage began in February this year. The work is taken up with a Rs 4.5 crore loan from National Bank for Agriculture and Rural Development (NABARD).

The barrage had been constructed in Mukkombu, where the River Kollidam branches out from Cauvery river, to store excess water for irrigation in 1977. Since then, no repair works were conducted. A PWD official said, "Though, there are many reasons, including the years, for corrosion of the shutters, the waste water released from the dying units in Karur district into the Cauvery river has worsens the condition of the shutters wreaked havoc to the shutters. Such chemical water corroded the bottom portion of the shutters in the long run. Hence, water-leakage takes place."

India - Water Contamination due to Corrosion - 60% rise in complaints of leaks in water pipelines, Kurla worst-hit

60% rise in complaints of leaks in water pipelines, Kurla worst-hit

At a time when the state is facing its worst drought in decades, precious litres of water are being wasted every day owing to leakages in the city's pipelines, which have risen by a whopping 61% since last year. Experts said that old, ill-maintained pipelines and a flawed distribution network are to blame. What's also worrying is that leakage contributes to contamination of water in the long run.

"The distribution system is flawed. Besides leakages in the century-old pipelines in the island city, the absence of a monitoring mechanism leads to wastage of more than 25% water every day," said former deputy municipal commissioner Prakash Sanglikar. "This could lead to contamination and affect public health."

Asserting that leakages in the corroding, old pipelines are a big reason for water contamination, experts demanded immediate action. "The BMC must take note of deteriorating pipelines, which have an alarming effect on the supply system and on health," said Nitai Mehta, founder-trustee, Praja Foundation.
