Several parts of the city were heavily inundated but South Delhi was among the worst-hit and reeled under severe traffic congestion.
Residents and commuters faced a tough time as the mouth of flyovers, underpasses and low-lying localities such as Sangam Vihar were flooded due to water-logging.
"Fortunately, it was a weekend and the water accumulated on major stretches had reduced significantly by the peak hours. Had it been a weekday, things would have gone worse," Special Commissioner of Police (Traffic) Sandeep Goel said.
Amid the troubles faced by Delhiites, BJP-led municipal corporations and the Public Works Department, which is under the AAP government, traded charges over desilting of drains.

Leader of the House in South Delhi Municipal Corporation (SDMC) Subhash Arya claimed the civic body had cleaned all drains under its jurisdiction while the problem was due to uncleaned drains falling under the jurisdiction of the PWD.
"All the (drains) under SDMC have been properly cleaned and silt had also been removed. The bigger drains, which the smaller ones ultimately join, fall under the jurisdiction of PWD and they were not desilted, and turned out to be the major cause of waterlogging," he said.
Commuters, who tried to take diversions from the arterial stretches, ended up being stranded in areas like Safdarjung Enclave, Defence Colony and Lodhi Colony, said a transport department official.
"Despite the large claims of all the three Municipal
Corporations that they had completed the pre-Monsoon desilting work, it was seen that a lot of silt was coming from the municipal corporation drains, thus reducing the capacity of the PWD drains, resulting in overflowing of the drains and causing water-logging at many places," the official added.
Water-logging at the mouth of the Indraprastha Flyover continued till noon, due to which the traffic coming from Rajghat and the elevated Ring Road had to be diverted. The problem was caused by sewer leakage, which appropriate civic bodies should look into, the official said.
The major road stretches that witnessed traffic snarls for long hours include the Ring Road stretch near Sarai Kale Khan, Mehrauli-Badarpur Road, Aurobindo Marg, the Outer Ring Road stretch covering Hauz Khas, Greater Kailash, Nehru Place and Modi Mill, and Mathura Road, officials said.
