BWSSB launches major pipeline replacement drive to prevent contaminated water in Bengaluru

After the Lingrajpuram incident, the water board moves proactively to replace decades-old Cauvery pipelines and ensure safe drinking water across the city.

In the wake of the recent Lingrajpuram contaminated water incident, the Bangalore Water Supply and Sewerage Board (BWSSB) has initiated a major preventive operation to avoid similar problems in the future. The board has decided to replace ageing Cauvery water pipelines across the city to ensure the supply of safe and clean drinking water.

BWSSB Chairman Ram Prasath Manohar said the board has become alert after identifying the root cause of recent water contamination issues. According to him, old and rusted pipelines are a major risk factor, as they can allow impurities to enter the water supply and pose serious health hazards to residents.

Bengaluru currently has a vast network of Cauvery water pipelines running for nearly 14,000 kilometres. Out of this, around 3,000 kilometres of pipelines are more than 40 years old. These ageing pipes are prone to corrosion and damage, increasing the chances of water getting contaminated before it reaches households.

Officials confirmed that the Lingrajpuram water contamination was also linked to the condition of such old pipelines. Learning from this incident, the BWSSB has now taken a firm decision to replace the outdated pipes at the earliest.

The replacement work will be carried out in a phased manner over the next three years. Priority will be given to areas where pipelines are the oldest and most vulnerable. The objective of this large-scale exercise is to prevent future contamination and ensure uninterrupted supply of clean drinking water to citizens.

The BWSSB chairman stated that once the old pipelines are replaced, the quality of drinking water supplied across Bengaluru will significantly improve, reducing health risks and restoring public confidence in the city’s water distribution system.
