The solid waste management machinery in the city is likely to be hit as garbage contractors have threatened to go on an indefinite strike from Monday. The contractors rent out transport vehicles to the Bruhat Bengaluru Mahanagara Palike (BBMP) for waste collection and disposal.

The strike call over a range of issues, which includes non-payment of bills for the past five months, coincides with the onset of the monsoon and the Ramzan, when the smooth functioning of the solid waste management system becomes all the more crucial.

The timing and duration of the strike has already raised fears of more black spots coming up on Bengaluru’s streets.

Balasubramanyam, a garbage contractor, said though the previous government had promised them that they would be paid as per revised rates in September 2017, the BBMP had not honoured the promise. “We will not resume work till our dues are paid,” he said.

The government is likely to hold a meeting with the contractors on Monday to resolve the issue. Deputy Chief Minister G. Parameshwara holds the Bengaluru Development portfolio.
