BBMP to set up leachate treatment plants at waste-processing units

In a first-of-its-kind initiative, the Bruhat Bengaluru Mahanagara Palike (BBMP) is planning to set up leachate treatment plants at two waste processing units – Kannahalli on Magadi Road and Chikkanagamangala near Anekal taluk.

The treatment plants, once set up, will remove ammonia and other contaminants from the leachate, formed when the rainwater mixes with waste.

BBMP Special Commissioner for Solid Waste Management (SWM), Subodh Yadav, said: “Leachate is dangerous and can deter vegetation on the land. During a recent meeting held by the SWM committee, we took a decision to set up plants to get rid of leachate and save the soil which it gets mixed with. The treated effluent can be utilised in many ways like washing, industries among others.”

The civic agency will send the proposal to the Urban Development Department and once approved, it will be taken up by the empowered SWM panel set up by the Palike. “After this, we will take suggestions of experts and later float a tender. We are yet to estimate the capacity of the plant, details of cost and other logistics,”  added Yadav. 

During the meeting, the need to set up CCTVs with Internet facility at all plants was felt. Washing of compactors after every disposal was also recommended. 

Also on the Palike’s anvil is disposal of temporary leachate of each plant at five locations. Palike officials said they have approached the Bangalore Water Supply and Sewerage Board (BWSSB) for permission for disposing of the leachate. “To start off with, we will start at Kannahalli and Chikkanagamangala. We will set up leachate plants at other units in a phased manner,”  said the SWM Special Commissioner.

Meanwhile, Bhagya S, a resident of Kannahalli, said: “Presently, leachate flows into shoulder drains from the garbage processing unit. We expect little help from the civic agency. It is to be seen whether the leachate plant will be a success or not.”
