Chandrawal is actually Delhi's oldest water treatment plant: it's been having a tough time lately. Just last month, a broken pipeline caused a nine-day shutdown.
There have also been valve issues and leaks over the past year, mostly because the equipment is getting old.
The good news: a new facility at Chandrawal should make things smoother once it becomes operational.
Till then, DJB says it's working hard to keep disruptions minimal and will send out tankers if needed.
