Delhi Plans Major Water and Sewerage Infrastructure Transformation
Delhi’s government says it is working to improve water and sewer systems.
It wants every home to receive clean water regularly.
The Asian Development Bank will help pay for many of the projects.
New water pipes and reservoirs are planned in several parts of the city.
These projects are expected to help millions of residents.
The government also plans to build 28 smaller sewage treatment plants.
Existing sewage treatment plants will be improved.
Sewer connections have already been added for many homes in unauthorised colonies.
Officials are also working on places where rainwater causes flooding.
