Bengaluru: Bengaluru Jalamandali (BWSSB) has devised a World Bank-assisted project to stop the flow of sewage water into 19 lakes under the BBMP.

 A plan to set up Sewage Water Treatment Plants (SPT) has been submitted to the World Bank and its approval is in the final stage. The Jalamandali has planned to complete the installation of STP in one year after getting the approval.

 As per the instructions of the National Green Tribunal, water supply and sewerage lines will be installed in 110 villages on the 'trunked pipeline' model. So that the sewage water does not flow outside. Millions of liters of sewage water from 38 villages and about 30 new layouts under their jurisdiction are directly entering the lakes every day. To prevent this, 9 STPs are installed to drain the treated water into the lake. From this, a plan has been made to drain only treated water in the lakes of this part and the series of canals after it.

 Along with these STPs 10 Intermediate Sewage Pumping Stations (ISPS) are also being set up. The total cost of the project including setting up of ISPS units near lakes where STPs cannot be set up and pumping sewage water to STPs is estimated to be around ₹1 thousand crore.

 A plan has been made to install STP and ISPS to prevent sewage water from flowing into 19 lakes. World Bank assistance has been sought for this and administrative approval has been obtained. As soon as the financial approval is received, the tender process will be completed and the units will be installed, said Jalamandali Chairman Ram Prasat Manohar.

Now a plan has been prepared to treat the sewage water of 38 villages. Similar units will be set up in 110 villages in the coming days. Financial assistance and grants are being checked for this,' he said.

 Action to stop sewage flows to all lakes: Ram Prasat

 "Sewage water flowing into lakes in the city is a perennial problem. This is being gradually reduced and steps will be taken to ensure that sewage water does not flow directly into any lake in the next few years. Only treated water is thought to flow into the lake. Ram Prasat Manohar, president of Bengaluru Jalamandali said that many projects have been prepared for this purpose and the water board will try to save the environment of the lakes.

•  9 Sewage Water Treatment Plant
•  148 mld Total capacity of nine STPs

Additional 10 TMC CAUVERY WATER to BENGALURU

 Reduction of excess water use in agriculture; Notice to water board to increase capacity

 Additional 10 TMC CAUVERY WATER to BENGALURU

Kere Manjunath ಕೆರೆ ಮಂಜುನಾಥ್

 BENGALURU: The government has decided to supply 10 tmc ft of additional water to Bengaluru city to save Cauvery water, which is heavily used in agriculture.

 The new settlements and areas of the city, including the 110 villages covered by the Brihat Bengaluru Mahanagara Palika (BBMP), need more water. Thus, the Bengaluru Water Supply and Sewerage Board (BWSSB) had submitted a proposal to the government that surplus water should be allocated. After reviewing this, the government directed the Cauvery Irrigation Corporation to review the feasibility of supplying additional water and submit a report.

 A committee led by technical experts conducted a review and found that 'rice, sugarcane and other agricultural crops are using much more water than required. If this is reduced, more water can be provided to Bangalore', the report said. Based on this report, the government has given in-principle consent to the BWSSB and suggested to increase the capacity to use the surplus water.

 Cauvery 5th phase project to supply water to Bengaluru is in the final stage and it is planned to supply water to 110 villages in April. On this occasion, it is intended to start the works to increase the capacity to collect and supply additional 10 TMC feet of water,'' BWSSB President Ramprasath Manohar informed.

 BWSSB uses 24 TMC feet of water from Cauvery annually, of which 20% is classified as 'Consumptive use'. That is, if using the water obtained from the river, 20% of it is returned to the river itself, there is a chance of getting that amount of water in excess. On this basis, the government has agreed to demand more water. Officials explained that most of the water used in the city is joining Kaveri River through Vrishabhavati, Arkavati and canal-valleys.

Consent in principle: Ramprasat

 A proposal was submitted to the government that due to the increase in the population of the city and the development of the areas, the allocation of water should be increased. BWSSB Chairman Ramprasath Manohar said that an in-principle consent has been given to save 10 TMC feet of water under the Cauvery Irrigation Corporation.

 Annual allocation of Cauvery water to the city

•  24 TMC Ft: Allotment as per Supreme Court judgment
•  19 TMC Ft: Water currently being used
•  5 TMC Ft: Water available for stage 5
•  34 TMC Ft: The total water allocation is 10 tmcft which the government has now agreed to

 Use of Cauvery water in the city

•  1,450 million litres: Daily supply of water in the city
•  1.6 TMC Ft: Water being supplied to the city every month
•  750 million litres: Additional water supplied daily on completion of 5th stage
•  2.4 TMC Ft: Current and Phase 5 water supply to the city every month

BBMp: Addition of 21 lakes to pollution list

 47 lakes developed at a cost of crores by BBMP, BDA are dirty; Dirt from BWSSB

 Kere Manjunath ಕೆರೆ ಮಂಜುನಾಥ್

Bengaluru: The lakes developed at the cost of crores of rupees by BBMP and BDA have become polluted sites due to the negligence of BWSSB and lack of monitoring by the State Pollution Control Board. As many as 21 lakes have the highest level (grade) of pollution in January itself.

The State Pollution Control Board has installed sensor measurements to measure water quality in 106 lakes in the city. According to it, the water quality of total 47 lakes is in the extreme 'E' grade. That is, the waters of these lakes are highly contaminated with metal, sludge and industrial pollution. It is not worth raising fish.

This is the condition of the lakes developed by BBMP and BDA. At least ₹5 crore has been spent on each lake. The pollution control board data itself proves that the lake has polluted water and what kind of development and pollution prevention works have been done.

Water Act not followed: 

As per the Water Act-1974, it is the responsibility of the State Pollution Control Board to take action to control all types of pollution. But, this function is not being done. They don't even give information to people. Ramprasad of Friends of Lake complained that the work is not being done.

When attempts were made to contact environmental officials, including the Chairman of the Pollution Control Board, they did not respond.

Quality is everything: 

A lake means the quality of the water in it is important. Apart from that, developing something will not be beneficial. Raghavendra B. of Action Aid said, "If the water is contaminated, the environment will be damaged, even after spending crores of rupees and making paths and tracks." Pacchapur expressed concern.

 Sewage water pollution

Sewage water is flowing into lakes. BWSSB has been told many times to stop this. They say there is no money to lay a new pipeline. If they stop the discharge of sewage water into the lake, the lakes will become pollution-free,” said Vijayakumar Haridas, Chief Engineer, BBMP Lakes Division.

 Lakes in 'E' grade of pollution

 Singhasandra, Parappana Agrahara Lake, Haralur, Rampur, Vibhutipur, Kammasandra, Rayasandra, Halasura, Halasura Lake (near Devasthan), Bairasandra, Gangondanahalli, Kachohalli, Machohalli, Doddabidarakallu, Shivpura Lake, Jakkuru, Amritahalli, Chellakare, Rachenahalli Lake, Singapore Lake, Bellandur Lake, Bhattanahalli, Elemallappa Lake, Kempambudhi, Nagawara Lake.

BWSSB STPs not following norms

 NGT Norm: only 8 out of 31 STPs are with in parameters

Kere Manjunath ಕೆರೆ ಮಂಜುನಾಥ್

Bengaluru: Out of the 31 STPs managed by BWSSP in the city, only 8 are treating waste water as per norms, while the remaining STPs are exceeding the norms of National Green Bench (NGT) and State Pollution Control Board, according to a report by ActionAid.

After 45 days of monitoring the statistics of STPs recorded on the BWSSB website itself, the agency has prepared a study report on them. 1042.5 million liters of waste water is treated daily in 31 STPs. Studied from Nov 1 to Dec 15, 2022. Six criteria are compared to assess the quality of water treatment.

Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Potential Hydrogen (pH), Total Suspended Solids (TSS), Ammonical Nitrogen and Total Nitrogen levels were studied following measurement. Raghavendra B.Pachchapur, Program Manager of ActionAid, said that except for 8 STPs, these standards are not being followed.

The TSS level should be less than 10 mg per liter as per Pollution Control Board standards. But BWSSB has set this level at 20 mg. Similarly, if the pH level is set at 6.5–9 instead of 6.5–8.5, there is no measurement of coliform, the human-animal waste that causes many diseases.

What SPTs are like?:

Only STPs at Doddabele, Cubbonpark, yelemallappa Chetty, Mylasandra, Kempambudhi, Rajacanal (New), Agar and Hulimavi are following all the norms.

Kengeri, Rajacanal (old), Hebbala, K&C Valley-30 and 218 are not providing sample data.

The data of STPs in Yalahanka TTP, Halasur, Bellandur Amani lakes is alarming and full of misinformation. Jakkuru STP is in very poor condition. Exceeds all standards.

All norms of National Green Bench (NGT), Pollution Control Board should be followed. It should be monitored by Pollution Control Board. The study suggested that the treated water discharged to the lake and other areas should be of the same standard.

'A fish is not worth living...'

BWSSB says water is discharged from its waste water treatment plants (STPs) into the lakes. The word people use is far away. At least the water in the lake is enough for the fish to survive. With such a purpose, we have studied the water flowing from STPs by collecting the data available on their website. A copy of this will also be submitted to BWSSB, Urban Development Department, State Pollution Control Board, ActionAid's Raghavendra B. Pachchapur said.

Upgradation will be done...

Many of the STPs of BWSSB are very old and cannot meet the norms laid down now. Thus, work is being done to upgrade the STPs to meet the NGT norms, informed Gangadhar, STP Department, BWSSB.

Kodigehallli Lake

Kodigehalli, Kannalli lakes polluted; Black water stinks

Kere Manjunath, ಕೆರೆ ಮಂಜುನಾಥ್ 

12 January 2023

Bengaluru: BWSSB and BBMP have finally yielded to the demands of the chairman, members, officers and locals of Kodigehalli village panchayat of Yeshavantpur area and have proposed to set up STPs to prevent sewage from flowing into Kodigehalli and Kannally lake.

Kodigehalli and Kannalli lakes, which are adjacent to Sir M. Visveshvaraiah BDA Layout, are under the jurisdiction of BBMP. Sewage and waste from Herohalli, Bydarahalli, Doddagollarhatti, Balaji layout, Anjananagar and BEL layout are being collected in these lakes. Locals and village panchayats have appealed to BWSSB many times that this should be stopped.

The lakes in Kodigehalli and Kannalli are smelling bad and causing trouble to the residents of the surrounding areas. Polluted water has turned black, mosquitoes and vermin have increased. The surrounding well and Borewell water is also getting polluted. Kommaghatta and Ramsandra lakes are also getting polluted and the chemical from here is entering Bairamangala lake. Repeated letters have been written to BBMP, Pollution Control Board and BESSB asking them to take immediate action. Now it has received a response and the water board has decided to install an STP with a treatment capacity of 3 million litres.

The water board has provided drinking water facility and sewerage system for Visveshvaraiah layouts. Kodigehalli and Kannalli lakes were getting a lot of pollution, and the locals had requested the Kodigehalli village panchayat to stop it. Thus, the Water board has decided to construct STP. Constructing a unit in an area of ​​one and a half acres, arrangements are being made to allow only treated water to flow into these lakes,'' said K.N. Rajiv, Chief Engineer, Planning Department, BWSSB.

The STP will be set up at a cost of ₹10 crore under Cauvery Phase 5 project with financial assistance from JICA. The project will be completed in a year and a half,' he said.

Kodigehalli and Kannalli lakes development have not been taken up by BBMP for development at present. However, we are supporting the water board work undertaken to prevent sewage spillage," said Vijayakumar Haridas, Chief Engineer of the lakes division.

Construction waste to Kannalli lake

Environmental activist Goudaiah has written several letters to the BBMP, Pollution Control Board since a year saying that construction debris, solid waste and meat waste are being dumped into the Kannalli lake. Responding to this, the BBMP directed the Kodigehalli village panchayat officer to take action to prevent such waste from going into the lake. But no action so far. Gowdaiah complained that the Pollution Control Board had conducted an inspection but no action had been taken.
