Several areas in the city, including parts of Old Madras Road and Ballari Road near Hebbal, and Bommanahalli, are already feeling the brunt of pre-monsoon showers.
Thundershowers on Thursday resulted in flooding at Anugraha Layout in Bilekahalli, where residents have come to dread the onset of monsoon.
Mayor Gangambike Mallikarjun, accompanied by a officials from the Bruhat Bengaluru Mahanagara Palike (BBMP) and the Bengaluru Water Supply and Sewerage Board (BWSSB), visited the locality on Friday.
Officials said that the inundation was the result of construction work on an underground drainage line. “When it rains, the stormwater drains overflow and the houses get flooded,” an official said.
Ms. Mallikarjun has directed the BWSSB to complete the construction of the drainage line on a war footing.
She has also instructed civic officials to use jetting machines to clear blockages and take up road repairs and Bangalore Electricity Supply Company to shift a transformer.
For the last four years, the railway underpass at Doddanekkundi, for instance, gets flooded every time in rains.
On Thursday morning, a school bus ferrying children was trapped in the water. Students had to be rescued by personnel from the Fire and Emergency Services using rafts. According to Doddanekkundi Rising, an association of residents of the area, despite continuous effort from BBMP and BWSSB officials as well as local councillor Shwetha Vijaykumar, the problem persists.
