India - Present awareness for corrosion is very limited in water infrastructure. Corrosion risk increases in an uneconomical way when water of varied composition is handled through pipeline networks with assets bearing mixed bag of materials of construction.

We come across numerous incidents of drinking water contamination with sewer system due to corrosion induced pipeline leakages. These pipelines have been laid very close to sewer transportation.


Contamination proliferates when the source water with contaminants is transported through water distribution system that uses a variety of unproven materials of construction.  We come across numerous incidents of drinking water contamination with sewer system due to corrosion induced pipeline leakages. These pipelines have been laid very close to sewer transportation. Our water supply concept significantly changed from the consumer owned water source to the collection and distribution managed by centralized water supply systems. Corrosion risk increases in an uneconomical way when water of varied composition is handled through pipeline networks with assets bearing mixed bag of materials of construction.  The present awareness for corrosion is very limited in water infrastructure. We need to turn Water Rust to Water TRUST to minimize corrosion induced pipeline leakages and conserve our present water resources.

Our national water policy should include norms for selecting suitable materials of construction and implementing corrosion control activities. Present water quality monitoring is not adequate to capture corrosive situations.
