Time to Replace 90,000 km Corroded Water Pipelines

Close to 90,000 kilometers of pipelines in the national water grid are old and dilapidated and must be replaced.
The national water network in cities stretches over 155,000 kilometers, of which around 25% (or 50,000 km) is decrepit in urban areas, IRNA reported.
Repairing one kilometer of the grid requires $30,000 and renovating the old and seeping pipelines will cost $1.1 billion.
