Brief Summary of the Project
1. Introduction
Bokaro Steel Plant (BSL) was set up and commissioned in the year 1972-73 for production of 1.7 Mtpa of flat rolled products. Subsequently, the plant was further expanded to 4.0 Mtpa for which EC was obtained in 1991.
BSL had obtained EC for expansion of crude steel production from 4 MTPA to 7 MTPA vide F.No. J-11011/99/2007-IA-II(I) dated 16.10.2008. However, BSL had amended the same for change in expansion capacity from 7.0 MTPA to 4.606 MTPA vide F.No. J-11011/99/2007-IA- II(I) dated 28.11.2014.
BSL is currently producing 4.606 MTPA crude steel. As part of modernization of the existing plant, Addition of a 2.0 Mtpa Pellet plant and 7m tall top charged Coke oven battery of 0.768 MTPA production capacity were also proposed within the same plant premises without increasing the approved production capacity of the existing plant. EC application for the same has been submitted to MoEFCC.
The required raw water for BSL plant operations and township is being drawn from Tenughat Dam which is built on upstream of Damodar River at a distance of about 35 Km from Plant site. The maximum limit for drawal of water from Tenughat Dam is 23140 m3/hr. At present, the raw water drawal by BSL is about 17500 m3/hr.
Water is supplied through a Gravity Canal which is controlled by WRD, Govt. of Jharkhand (Tenu canal which is about 35 km long from the dam). The canal discharges water into the Cooling Pond-l (which serves as the recirculating basin for the plant). The Canal is mainly built with earthen embankments, has PCC lining and has intermittent civil structures like RCC aqueducts or cross drainages over the nalas, small seasonal rivers, low lying land etc.
The canal is more than 50 years old. Its condition has deteriorated considerably. At many places the canal lining is damaged. The problem is more pronounced at junction points of aqueducts and canal. The canal's water discharge capacity has also reduced due to siltation over the entire length of the canal. There was a major breach in the canal, due to poor condition, causing complete disruption in water supply to BSL, which is effecting plant operations very often.
BSL is therefore, contemplating an alternate pipeline route for water drawl from Damodar River via Baidhmara Weir near Bokaro (approx. 5 km), to meet the water requirements of the plant and the township as an alternate route (same source) of raw water, which is found out to be the most suitable and feasible solution. On completion of the proposed project, Tenu canal can be taken up for repair. In future, this will serve as a standby arrangement to Tenu canal during exigencies. The amount of water which is being released from Tenughat Dam will be diverted through Damodar River and same water will be drawn from the upstream of Baidhmara weir by creating a pumping facility with pipe lines up to cooling pond - 1 for which NOC from Govt. of Jharkhand, Ministry of Water Resource Deptt. has already been obtained on January 06,2017.
Central Water and Power Research Station, Pune (CWPRS) was consulted for studying the feasibility of drawing the required quantity of raw water from upstream of existing Baidhmara weir and installing requisite intake facilities. CWPRS opined that proposed site is suitable for creating an intake and pumping facilities.
2. Site Location
The existing BSL plant is located in Bokaro Steel city, Sub-division Bokaro of Bokaro District in Jharkhand, between longitude 86o 02’ to 86o10’E and latitude 23o38’ to 23o42’ N near River Damodar. Baidhmara Weir is located North of the existing plant at a distance of about 5 Km. The exact GPS coordinated of the weir are 23o44’XX” N and 86o3’XX” E.
3. Environmental Setting
The route survey has already been carried out and the land of ROW (right-of way) does not involve any eco-sensitive area and forest land.
4. Land
The total land for the proposed route and facilities is already under possession of SAIL/Bokaro Steel Plant and no further acquisition of land is required.
5. Water
There shall be no change in the present water required for the existing Steel Plant complex and township.
6. Facilities Envisaged
For the intake and pumping facilities at Baidhmara weir following major facilities are envisaged- Water intake facility Water Pumping facility along with Electrical System Pipeline and spillway from intake pump house to Cooling pond-1 of BSL.
7. Project Cost Estimates

1. SUMMARY
1.1. Bokaro steel plant (BSL) has only one source of raw water for running the plant & township i.e. Tenughat Dam, built over the river Damodar. From the dam, the water is drawn through a canal about 35 km long in gravity to the Bokaro steel plant.
1.2. Canal is about 50 years old and is poor condition. Also due to siltation capacity of SUMMARY the canal has reduced. 1.3. Recently, in the month of November, 2016 there was a major breach in the canal, due to poor condition, causing disruption in water supply resulting into keeping down plant operation for 9 days. 1.4. In order to repair the canal and to eliminate dependency on single route, BSL has requested CET to study an alternate route for raw water supply to Cooling Pond-I, BSL. 1.5. On completion of the proposed system, Tenu canal can be taken up for repair. In future, this will serve as a standby arrangement to Tenu canal during exigencies. 1.6. The project is envisaged to be implemented within a period of nine (09) months from the date of Stage-II approval. Pre-ordering activities are envisaged to be completed within ten (10) weeks from the date of Stage-I approval. Implementation strategy has been detailed in Chapter 5. 1.7. The indicative requirement of manpower for the entire facility is 15. Supervisor will be redeployed from existing manpower of BSL, other persons will be hired on contractual basis. 1.8. The capital cost of the project is estimated as Rs. 118.45 crore net of CENVAT Credit of Rs. 7.56 crore including IDC of Rs. 3.97 crore 1.9. The project is a technical requirement and technically feasible, hence recommended for consideration.

2. BACKGROUND 2.1. WATER SUPPLY ARRANGEMENT OF BOKARO STEEL PLANT 2.1.1. Bokaro Steel Plant is the fourth integrated plant in the Public Sector and started production in 1972. It is located in Bokaro district of Jharkhand. 2.1.2. For fulfilment of raw water requirement, BSL has an agreement with Government of Jharkhand for withdrawal from the river Damodar. 2.1.3. Water requirement of BSL plant & township is fulfilled by Tenughat dam on
Damodar River. Water is supplied through a gravity canal (Tenu canal) about 35 km BACKGROUND long from the dam. 2.2. EXISTING RAW WATER DRAWAL SYSTEM 2.2.1. Water from Tenughat Dam is released through a separate exclusive gate into the Tenu canal. This canal discharges into Cooling Pond-I of BSL which serves as a recirculating basin for the plant. The central water recirculation scheme of BSL is shown in Annexure no 2.2.1-1. 2.2.2. The ownership of the Tenu canal and also maintenance responsibility lies with Jharkhand government. 2.2.3. Canal is mainly built with earthen embankments, has PCC lining along the full length and has intermittent civil structures like RCC aqueducts or cross drainages over the nalas, small seasonal rivers, low lying land etc. 2.2.4. It also caters to the irrigation as well as public needs of the adjoining areas. 2.2.5. The salient features of the existing system are a follows.
Sl. No. Feature Quantity (m3/hr)
1 Maximum withdrawal permission 23140
2 Original capacity of canal 23000
3 Requirement of BSL Plant & Township 19500
4 Present flow received at Cooling Pond - I 17500
5 Minimum withdrawal permission 15291
2.2.6. The canal is more than 50 years old. Its condition has deteriorated considerably. At many places the canal lining is damaged. The problem is more pronounced at junction points of aqueducts and main canal. 2.2.7. Heavy siltation has taken place over the entire length of the canal leading to lowering in withdrawal capacity.
BSL
2.2.8. The long stretch of the canal makes continuous monitoring difficult leaving the stretch open to potential threat of unnoticed breaches. This has happened on several occasions in the past. 2.2.9. A table showing changes in water levels of cooling ponds vis a vis break down of Tenu canal is attached as Annexure- 2.2.9-1. 2.3. REVIVAL OF EXISTING SYSTEM 2.3.1. The canal urgently needs major repair including strengthening of embankment, relining of damaged parts, repair of aqueduct joints and other such deficiencies.
BACKGROUND 2.3.2. A repair of such magnitude will require shutdown for minimum six (06) months whereas the emergency storage available at BSL in cooling ponds- I & II for 7 days onlly. 2.3.3. In this condition it is imperative to create an alternate facility for supply of raw water from Damodar to Cooing Pond – I. Laying a suitable pipeline parallel to the existing Tenu canal, as a probable alternative, has not been considered due to the following reasons: Approx. 35 km long pipeline from Tenughat Dam up to BSL. High capital cost involvement. New land has to be acquired.
The system shall not be under the control of BSL and shall remain under State government similar to the Tenu canal. Difficult to monitor and maintain due to location away from Plant. 2.4. Hence, drawing water from Baidhmara weir near Bokaro, as an alternate source of raw water, was found out to be most suitable and feasible for the following reasons. Supply assurance: The amount of water which was being released from Tenughat Dam can be diverted through Damodar River. Same water can be drawn from the upstream of Baidhmara weir. Existing weir: There will be no need to construct new impounding structures as the existing Baidhmara weir can be utilised. This will considerably reduce the implementation cost and period. Availability of land: The land near Baidhmara Weir and the proposed pipeline route belongs to BSL. There will be no need for additional acquisition of land. Proximity: Baidhmara weir is approx. 3.5 km away from cooling pond- I. 2.5. In view of the above, BSL vide letter Ref No. GM(P)/PPM/82/213 dated 18.11.2016 appointed CET as a consultant for detailed study of scheme related to Development of alternate system for drawal of raw water from Damodar River. Copy of this letter is attached at Annexure – 2.5-1.

2.6. CET accepted the assignment vide letter no CET-17(3)/018/16/435 dated 19.12.2016. The acceptance letter is attached at Annexure 2.6-1. 2.7. BSL has also consulted Central Water and Power Research Station, Pune (CWPRS) for studying the feasibility of drawing required quantity of raw water from upstream of Baidhmara weir and installing intake facilities. In this regard, a team comprising of BSL and CET visited CWPRS on 24.11.2016. 2.8. A team of CWPRS scientists have also visited the proposed site, Tenu canal, Tenughat Dam and cooling pond I on 07-08.02.2017. The minutes of meeting held
between BSL, CET and CWPRS is attached at Annexure 2.8-1. BACKGROUND 2.9. BSL has already obtained permission from Jharkhand government for drawal of water from Baidhmara weir and release of corresponding quantity from Tenu dam to Damodar river. Copy of permission letter is attached at Annexure 2.9-1. 2.10. CET gratefully acknowledges the co-operation and assistance extended by BSL in preparation of this feasibility report.
