The River originates on the south eastern slopes of Chennakesava Hills, northwest of Nandidurg of Chikkaballapur district in Karnataka State at an altitude of 1000m above mean sea level, which flows in the southern direction through Chikkaballapura, Bengaluru Rural and Bengaluru Urban districts in Karnataka state and descends to Tamilnadu near Hosur.
[7]Thenpennai river basin is one of the largest rivers of the state of Tamil Nadu. The river has supported many a civilizations of peninsular India in supplying precious water for drinking, irrigation and industry to the people of the states of Karnataka, Tamil Nadu and Pondicherry.The total length of Ponnaiyar River is 432 km, of which 112 km lies in Karnataka state, 180 km in Dharmapuri andKrishnagiri, 34 km in Thiruvannamalai and 106 km in Cuddalore, Kallakurichi and Villupuram districts of Tamil Nadu before joining Bay of Bengal. En route, it branches into Chinnar, Markanda, Vaniar and Pamban rivers in Tamilnadu. With a total catchment of approximately 16,019 km', it is dry for the most part of the year but swells during the north Karnataka, the river traverses through series of zilla vat tanks and also Minor Irrigation tanks andi tank, sewage of Koramangala&Challaghatta andHebbal valleys of Bangalore adds to the flow in river T. henpennaithereby causes frothing of river stretch.
CHAPTER -- 4 4.0 Preliminary Joint Committee Survey and Investigation Joint Committeeconducted a_ preliminary survey during 28.08.2020 and 01.09.2020, in order to investigate thecurrent scenario of River flowing in both the states (Karnataka and Tamilnadu). The findings of the preliminary reconnaissance survey of [8] Chikkaballapur, Kolar and Hoskote districts in Karnataka are given below:
(A) Chikkaballapur District:South Pinakini river flows in Chikkaballapur, Siddlaghatta and Chintamani (border) taluks in Chikkaballapur District.
The basin of the river is very small and for majority of the period in a year, the river basin remains dry.
Since this river connects many tanks, water flow can be seen only when the tanks overflows.
Under Chikkaballapur district jurisdiction, on the banks of this river, no major industries can be seen.
Photographs of the river between Bommanahalli tank and Yarragolu dam. Water will be used for drinking purpose by people in 3 taluks namely Kolar, Bangarpet, Malur. Finally the discharge of Yarragolu dam water joins the valley of south pennar of Krishnagiri district in Tamilnadu state.
Photographs of the river flowingin Markandaya tank of Bangarpet taluk are given as Figure 3.
(C) Hoskote District: South Pinakini river flows in Hoskote and Anekal (border) in Bangalore Rural District. The basin of the river is very small and for majority of the period in a year, the river basin remains dry.
[9]e Since this river connects Hoskote and Channasandra tanks, water flow can be seen only when the tanks overflows. e Under Hoskote jurisdiction, on the banks of this river, no major industries can be seen.
Photograph of Hoskote tank in Hoskote taluk is given as Figure 4.
In addition to above, preliminary reconnaissance survey of River basin of South Pennar flowing in Bangalore district was also conducted and the observations are given below; (D) Bangalore District:Survey was carried out in the areas of River South Pennar drainage basin covering Hebbal Valley and Koramangla / Chalghatta Valley, wherein«.series of lakes/tanks gara, Bellandur, Varthur (K & C Valley adugodi bridge, Channasandra bridge (Hebba:
enabling flow of wa eyish in varthur e networking is d by 2023) .
1 same will be comp iii. Two weirs of Hoskote tanks' were observed to be having less water and no flow was found during the visit.
iv. Further, water flowing in Mugalur (KSPCB monitoring location) was also observed to be frothy and greyish, where few piggery units were found discharging washings/effluent.
v. Some micro/small scale dyeing units were also found operational illegally and discharging untreated effluent down the drain nearly 50 maway from the river stretch in Samethanahalli and immediate actions were taken by Karnataka SPCB to close those units.
[10]vi. Also, a few other non-operational/closed and dismantled dyeing units in Samethanahalli and Thiruvaranga were also visited during the survey. In Samethanahalli, water was observed to be flowing greyish and frothy, where few dyeing units were found dismantled and non- operational.
vii. It is prudent to be noted that, washings and droppings of piggery farms located in samethanahalli and thiruvaranga add to organic load of the River flowing in Samethanahalli.
vil.Information regarding number of STPs (operational status) and proposed STPs (capacity) of K&C Valley and Hebbal valley was explained by Bangalore Water Supply and Sewerage Board (BWSSB) during the survey with the help of layout map..Desilting work carried andur and Varthur tanks was also ired by Bangalore Jepment Authority (BDA).

4.2 Excerpts of Thenpennai River Monitoring in the matter of O.S No. 2 of 2015& O.A No. 125/2017 In compliance to Hon'ble Supreme Court directions in the Original Suit No. 02 of 2015, ajoint monitoring Report on River Cauvery and Thenpennaiyar was submitted by CPCB, KSPCB and TNPCB, wherein the monitoring team carried out sampling of water for the period September 2017 to May 2018. The committee filed the report before [15] the Hon'ble Court in 2018 (the case is pending before Hon'ble Supreme Court). The findings of the Report is given as below:
1. In case of River Thenpennaiyar at Sokarasanapalli, the water quality falls below designated best use Class C during all nine monitoring and the critical parameters are BOD, DO and TC. The Total Coliform was always > 5000 MPN/1000 ml and DO was <1 except during January and February 2018 showing the DO as 2.4 and 3.8 mg/l respectively. BOD also exceeded the Sewage standards notified 20 mg/I for all nine months showing the water is highly polluted.
2. The River Thenpennaiyar receives the outflow of treated and untreated sewage of Bellandur and varthur lake system.

In this regard, summa. f- Compliance Report to the observations of the Monitoring Committee in respécck of BWSSB, BDA, UDD, Minor Irrigation and KSPCB was filed before Hon'ble NGT, Principal Bench on 04.08.2020, wherein Hon'ble Tribunal vide orders dated 13.08.2020 has directed that "...the left-over work may be expeditiously completed which may be reviewed by the Monitoring Committee. The status of compliance as on 31.12.2020 may be compiled by the Monitoring Committee and report furnished to this Tribunal by 15.01.2021...".
[16]4.3 Major Sources of Pollution Major sources of pollution to River Thenpennai appear to be from untreated/partial treated sewage from Bangalore. Sewage generated from Bengaluru is the predominant reason for deterioration of lakes and water bodies in Bangalore, which is ultimately flowing into river Thenpennai.
There are various reasons such as ageing of sewers, encroachment of sewers, damages in the sewerage system, crown corrosion of sewers etc. for direct discharges of a part of wastewater from housing colonies and such discharge is flowing through Storm Water Drains and enters lakes in Bengaluru. Lakes in Bengaluru were created for rain water harvesting and once served as sources of water e city. Lakes are under the custody o jangalore Bruhat Mahanagara Palike ¢ sewage treatment plants, encroachment.of lakes and Rajakaluves (storm water drains), dumping of municipal solid waste, construction and demolition wastes, illegal discharge of industrial effluents etc.The foremost reason for pollution of Bellandur Lake is sewage/ Sullage flowing in the storm water drains. One of the main reasons for development of foam in the waste weir is agitation of water falling over a height and due to surfactants present in sewage. Now after establishment of sluice gate and weir modification development of foam reduced considerably. Additionally, fertilisers used by farmers of [17] Karnataka as well as Tamilnadu may add to the pollution of river thenpenna Sd 4 Status of Domestic Sewage Management in Bangalore Sewage is one of the major causes for poor water quality of rivers, lakes and water bodies causing adverse impacts on human health and aquatic species. Bangalore Water Supply and Sewerage Board (BWSSB) was formed in 1964 to provide Sewerage system in unsewered areas in Bangalore in a phased manner. Domestic Sewage generation in Bengaluru has been estimated as 1157 MLD which is attributed to increased urbanization and population.The actual amount of sewage generated would be higher since a large number of private bore wells exist and re is no scientific estimate of the quantity of water Status of Sewage Treatment Plants of K&C and Hebbal Valleys in Bangalore, as provided by BWSSB is given as Annexure IV. Domestic sewage generation of hamlets/areas located in the stretch of Hebbal and K&C Valley, Bangalore is around 420 MLD & 611 MLD respectively, of which 814.5 MLD is being treated in 21 STPs located in the two valleys. BWSSB informed thatin hebbal valley, 03 STPs of 100 MLD, 20 MLD and 10 MLD capacities are under construction phase and the same will be commissioned by Dec 2020. In addition to that, construction of one STP with 07 MLD capacity is also under pipeline in hebbal valley.In case of [18] Koramangla & Chalghatta valley, of 02 STPs, one STP (150 MLD) will be commissioned by Dec 2020.
In compliance to Hon'ble Supreme Court directions in the Original Suit No. 02 of 2015, Chief Secretary, Government of Karnataka submitted to Hon'ble Supreme Court in 2018 that, fourteen STPs of total 129 MLD for 110 villages under Japan International Cooperation Agency (JICA) Fund Scheme were proposed. It was then assessed that, with the establishment of those STPs, the total capacity of STPs to treat the sewage from Bengaluru would rise up from the existing capacity of 1050 MLD to 1575 MLD by 2020 and 1704 MLD by 2022.
In addition to above, as per the Government of Karnataka No. FEE 316 EPC 2015, Bengaluru dated 19.01.2016, ance is required for the following projec idential group housing projects/apartment: units and Educational institutions with or without hostel facility built up area of 5,000 sq.m.and abov ment projects with an area consent mechanism are required .to- provide Sewage Treatment Plant (STP) for treating the sewagé. "Howevir: sewage generated from the smaller projects like apartments with less than 20 flats, commercial buildings with less than 2000 sq.mts built up area are required to be treated by BWSSB.
KSPCB has filed two Criminal cases against BWSSB w.r.t pollution of Bellandur Lake. Further, as per the directions of Hon'ble NGT in the matter of O.A.125/2017, Karnataka State Pollution Control Board has imposed Environmental Compensation against the defaulting Apartments/Housing Associations. Few projects have approached the [19] Hon'ble High Court of Karnataka in this matter. As per the directions of Hon'ble High Court of Karnataka,Karnataka State Pollution Control Board is following the due procedure.
CHAPTER V SAMPLING AND ANALYSIS OF RIVER THENPENNAI 5.0 Sampling Locations The Joint Committee identified the following sampling points for collecting surface water samples based on the _ reconnaissance surveyconducted in Tamilnadu and Karnataka during 28" August and 01"

Thenpennai River basin Map showing the sampling locations in Karnataka and Tamilnadu are given below as Figure 8;
Geographic profile and details of the sampling locations in the sequence of the flow of River Thenpennai is provided below;
() Agara:
[20]Agaralake spread over 98 acre, is located at Agara in southeast direction of Bengaluru. The lake receives outfall from the upstream Madivala lake.The excess water from Agara lake overflows through the storm water drain to Bellandur lakenear southwest direction. At varthur, the flow of water was found clear and no frothing was found. However, domestic sewage and solid waste was found mixed down the drain with greyish color leading to Bellandur.
Gi) Bellandur:
Bellandur Lake is located in southeast direction of Bengaluru and is the largest lake in the city and the weir flow of Agara Lake joins Bellandurlake. It was observed that, of the two Bellandur Lake weirs, water was flowing in one weir towards Southern direction (near The Varthur Lake-takes the main inflow from outflow weirs of Bellandur Lake, along with. sowie other-water entry points (about 6 to 9) between outer ring road (that connects Marathalli with Sarjapura road) and Varthur, between which the Varthur Lake lies. It was seen that Varthur Lake has 02 outflow weirs viz: Northern weir near Sigma Softech Park, Ramagondanahalli (popularly called as Varthur Kodi) and Southern weir near Varthur (popularly called as Varthur Bridge).
Even in varthur lake, water was flowing only in southern weir as the Northern weir was taken up for restoration work by BDA.It was informed that both the weir flow of the lake joins at a point at about 600 [21] m in South Eastern direction of the Northern weir, thereafter, the stream joins the South Pennar River, through Ajjigondahalli bridge, at about 3.8 Km in east of north eastern direction. The joined streams of out flow weir of Varthur Lake flowing en route, Ajjigondahalli Bridge, represents entire wastewater / domestic effluent of K & C Valley flowing into South Pennar River. At varthur, the flow of water was found greyish to brown and no frothing was found.
(iv) Channasandra:
Channasandra Bridge located on Hope Farm Junction towards Chikka Tirupathi Road, flows in Southern direction in order to further confluence with the out flow of Varthur Lake (K & C Valley).
Whereas, lakes of Hebbal Valley flows into Yelemalappa Chetty ( ke) located on Old Madras Road. O er ir of YMC Lake joins the South Pennar River:
flow through the Few unauthorized micro/small > dyeing units were found operational during the visit and found discharging untreated effluent down the drain. KSPCB has taken immediate action to close those units.
(vi) Mugalur:
Mugalur Bridge is on Sarjapura -- Chikka Tirupati road which is at a distance of about 11.47 Km south east of northern weir of Varthur Lake. The South Pennar River leaves Karnataka State and enters into Tamil Nadu and joins Kelavarapalli reservoir (about 7.5 Km north east of Hosur city) which is located at about 14.18 Km south east of Mugalur Bridge. At Mugalur Bridge, the flow of water was greyish to brown and it contained [22] scanty pockets of froth here and there. Solid waste dumping and outlet of piggery farm into the river was found near the area.
(vii) Sokarasanapalli:
Sokarasanapalli is located at interstate border of Tamilnadu and Karnataka with a distance of 500 m from the river bed.
Sokarasanapalli is an interstate water quality monitoring location being sampled by Karnataka on a quarterly basis. The flow of water in sokkarasanapalli was observed as greyish and with growth of floating aquatic plants in a large area.
(vii) Kodiyalam:
Kodiyalam is situated in north east direction of Hosur district, kodiyalam, there is one anicut o distributewater flowing from arasanapalli for urpose. Central Water Commission, Catty Kelavarapalli dam is located in the Northwestern part of Tamil Nadu.400 cusecs of water was found flowing through spiihway shutters with reasonably clear water in green color on the dav of visit. Aiso scantv pockets of froth was seen due to water Mowing with force from hich fall of the dam.
In the areas namely, samethanahalli, mugalur, sokkarasanapalli, kodiyalam, bagalur kelavarapalli water was found being pumped and used for agriculture in the nearby areas.
5.1 Sampling Protocol [23] The surface water samples of the above identified 12 locations in River Thenpennai were collected during 09 and 10° September, 2020 and submitted to laboratory for analysis. The Joint Committee followed CPCB's Standard Operating Procedure for National Water Quality Monitoring Programme and Submission of data developed in August, 2017. The scope of the SOP is to standardise the process of sample collection, preservation, handling and analysis, preparation of data reports, etc. The analysis results of the aforesaid surface water samples of12 locations in River Thenpennai are awaited.
Submission of Joint Committee to the Hon'ble NGT, Southern joint Committee constituted in O.A No of.2020,is of the t to complete the assigned tasks as per T : report to CPCB, if there is any violation found; (ii) t ti quailty and also ascertain the sources of pollution an incorporating the a 'taken, Action Taken Report on defaulters, Long Term..and Short-Term Action Plan with shorter timelines, Recommendations, etc. in compliance to the Hon'ble NGT Orders dated 20.07.2020."
5. It is seen from the report that water analysis has not been completed and the environmental compensation has not been calculated for which they require six weeks time.
