Bring Back the Lakes

Revival of Bengaluru Lakes

Date: 13th June’2016

Karnataka Lake Conservation & Development Authority (KLCDA)

Brief History

• The City built by Sri.Kempegowda, 468 years ago, has well-

developed natural drainage system. Bangalore had more than 400 lakes, interlinked by a system of canals (Rajakalave) that followed the natural gradient of the land in which excess water from one lake would flow through waste-weirs into the next lake/ tank, thereby preventing flooding. This system could be maintained for a long time, through the colonial period, till more recent times. This has contributed enormously for creating micro climate in the City as well high level of recharging of ground water in the city.

PART -I – AN OVERVIEW

• Bangalore - “The City of Lakes”
• Kempegowda (16th Century)
• Founder of Bangalore
• Established several tanks for
• Drinking
• Irrigation
• Domestic purposes
• Maintain the water-table
• Flood mitigation
• To enhance the beauty of ‘Garden

City’

Details of BBMP areas & Water supply/ Waste water generation in Bengaluru (BWSSB)

• Bruhat Bengaluru Mahanagara Plaike (BBMP) comprises of 800 Sq Kms

consists of core area (245 Sq Kms), erstwhile CMC/ TMC (330 Sq Kms) and 110 Villages (225 Sq Kms)

• BWSSB is supplying 1400 MLD of water from River Cauvery. It is estimated

that about 250 MLD water is utilized from bore well supply (public + private). Total water supply is 1650 MLD.

• Out of the quantity of water supplied, 80% will convert in to wastewater. It

is estimated that 40% of the quantity of wastewater generated will flow towards Vrishabhavathi valley, 40% towards Koramangala and Challaghatta Valley and 20% towards Hebbal valley. Vrishabhavathi valley joins Arkavathy river which in turn joins River Cauvery at Sangam, Kanakapura

• taluk. Koramangala, Challaghatta and Hebbal valleys joins South Pinakini

river which in turn joins Penniyar river.

• As on today, core area & erstwhile CMC/ TMC area covering

550 Sq Kms is supplied with Cauvery water and rest depends

• n bore well water (public & private).
• Core area is provided with UGD network of 3300 Kms lateral

and 300 Kms of sub-mains, mains and trunk sewers. Laterals are repaired/ replaced/ rehabilitated as and when required with Board funds and in case of sub-mains, mains and trunk sewers involves huge costs depends on outside/ external funding

• In respect of erstwhile CMC/ TMC area, providing of UGD

network is in progress under KMRP/ JnNURUM/ State/ Board

• funds. Laterals of 2400 Kms and submains/mains/ trunk

sewers of 340 Kms is being provided as UGD. Work is in progress and expected to be completed by end of 2016. Contd….

• With respect to 110 Villages, a Detailed

Project Report costing Rs.2800 Cr for water supply component and Rs.2300 Cr for UGD facilities including Road restoration totalling to Rs.5100 Cr is approved by GoK, cleared by CPHEEO and now it is with DEA for external funding from JICA. The project includes water supply and 2590 Kms of UGD network. Requires 4 to 5 years for completion when

• nce it is approved.

Wastewater Treatment –

• Existing – 14 Nos. – 721 MLD capacity – treating up to

80% capacity due to connectivity problem – works are under progress – full capacity utilization by end of 2016

• Under Constructions – 10 Nos. – 336 MLD capacity –

expected to be completed – K & C Valley by March 2017 – V Valley by end of 2018

• Some of the projects of BWSSB are recently approved

and some of them are in pipeline. After the commissioning of these treatment plants the total treatment capacity will increase to 1761 MLD by 2020.
