Jannah Dam construction project.

02 August 2014





 Jannah Dam construction project. 


The most important difficulty faced by the Authority is the lack of new sources of water and its water deficit, compounded year after year, and the state is unable to help, especially as it faces many problems and is burdened under the weight of a large public debt. 

Since the Authority is the interface receiving first these complaints,
 
Since the administrative and financial status of the Authority is sound and solid, especially after enjoying a funds liquidity.
 
After consulting several legal and economic references, the Authority began to work towards assisting the Ministry of Power and Water Resources to construct the Jannah dam (with a capacity of 38 million cubic meters), which feeds the areas of Byblos and Beirut and its suburbs.
 
It has been agreed upon sending a letter to the Audit Department to ask for its opinion about the possibility of the Authority to establishment the Jannah Dam under the approval and supervision of the Ministry of Energy and Water. 

The Audit Department issued the Advisory Opinion No. 41 / 2009 Date 24 / 4 / 2009, which concluded that "the Water Authority of Beirut and Mount Lebanon will have the possibility to establish dams within its competence and exploit the same to secure drinking and irrigation water for subscribers as long as it has a technical and financial solvency after the approval and supervision of the Ministry of Power and water resources ". 

On 24 / 4 / 2009 the Cabinet adopted the Resolution No. 76 on the construction of the Jannah dam and lake on the River of Nahr Ibrahim, to provide water to the area of Byblos and Beirut and its suburbs, which mandated the Ministry of Energy and Water, in coordination with the Council for Development and Reconstruction and the Water Authority of Beirut and Mount Lebanon to complete the study of the dam and allocate the funds needed to implement it. 

After several meetings held with the Minister of Energy and Water, and upon studying the process of this project, the Board of Directors of the water Authority of Beirut and Mount Lebanon adopted the following three resolutions : 

- Resolution No. 79 of 2 / 6 / 2009 ordering to approve the establishment of the Jannah dam and lake on the River of Nahr Ibrahim in the district of Byblos Mount Lebanon Governorate, which has been approved duly by the Ministry of Energy and Water, in its vide letter No. 1809 of 10 / 6 / 2009. 
- Resolution No. 80 Date 2 / 6 / 2009 ordering to approve a Memorandum of understanding  between the Ministry of Power and water resources and the Authority regarding this vital and important project, which has been approved by the Ministry of Energy and Water, in its vide letter No. 1810  /  6 of 10 / 6 / 2009 after being signed by HE the minister. 
- Resolution No. 81 of 2 / 6 / 2009 ordering to enact a public benefit decree to expropriate several properties relating to this project. 

On June 22nd, 2009 the decree No. 2280 was issued and ordered " to consider the works relating to the project of establishing the Jannah dam and Lake for water storage and hydroelectric power station and technical and administrative installations thereto at Nahr Ibrahim (Byblos - Mount Lebanon) as public benefit in favor of the Water Authority of Beirut and Mount Lebanon. 

Based on the first article listed in the Memorandum of understanding aforementioned, a joint committee between the Authority and the ministry should be composed to monitor and follow up the work of this project. The Board of Directors adopted the Resolution No. 116 of 10 / 9 / 2009 ordering to approve the nomination of the members of the Joint Committee the Authority and the ministry and conclude contracts with them based on the motion of the Minister of Energy and Water. 

The Authority began to request all documents related to this project from the Ministry of Energy and Water, 

It obtained the same and held several meetings with " Khatib & Alami " which is the studies consultancy firm assigned by the Ministry of Power and water resources to prepare the study. 

On 12 / 7 / 2010 the Minister of Power and water resources issued a decree amending some points featured in the Memorandum of Understanding between the Ministry and the Authority for the implementation of the Jannah dam project.
 
On 16 / 9 / 2010 the Board of Directors adopted a resolution No. 132 amending the members of the Joint Committee between the Ministry and the Authority relating to the Jannah Dam Project based on the letter of the Ministry of Power and water resources under the No. 93 of 02 / 08 / 2010.
 
On this basis, the Committee began its work and a contract was concluded with "Khatib and Alami" to complete the studies for the project pursuant to the decision of the Board of Directors No. 171 of 9 / 11 / 2010 and after the approval of the Ministry of Energy and Water, in its vide letter No. 3699 of 29 / 11 / 2010. 

About the project and the time schedule of the studies phases and execution :
 
Project’s Description 
The establishment of a dam on the River of Nahr Ibrahim on the debit of 735 m with the following specifications: 
- a dam made of concrete compacted with a roller 
- Height of the dam 100 meters 
- Capacity of the lake 38 million cubic meters approximately (up to 90 million) 

The goal of the project 
Securing additional quantities of drinking water annually to central areas of the coast of Byblos, in addition to Beirut and its suburbs, including the following: 
- Byblos  area: about eight million cubic meters 
- Area of Beirut and its suburbs: about thirty million cubic meters 

The project will include the establishment of a power plant with a capacity of 40 MW. 

Phases of the project 

1 - The first phase 
The study of the first phase of the project was completed and included the conversion tunnel and roads relaying the site of the dam and the bid documents were prepared and the Authority declared that the bids may be submitted and opened on 18 / 4 / 2012 noting that the duration of the project in the first phase is one year. The Board of directors approved in its resolution No. 21 on 26 / 5 / 2012 to conclude a second contract for additional studies with “ Khatib and Alami “ for 823.911 million of LBP, which included, in addition to the preparation of the tender documents of the first phase, three other items:
 
The Installation of the gates for the tunnels excavated by the consultant within the first additional studies contract. 
Expansion of the road of Kartaba. 
Preparing the dynamics three-dimensional seismic study of the dam.
 
The bids were opened on 18 / 4 / 2012, and the contract was awarded to the best bidder Union Engineering & Trading SAL. However, the Contractors’ notification was delayed due to non issuance of the amended decree of expropriation. The Board of Directors has issued the Resolution No. 16 on 19 / 1 / 2012 requesting the amendment of the Decree 2280 of 15 / 4 / 2009 due to the modification of the design of the dam. After several deliberations with the Directorate General of the Presidency of the Cabinet a decision was adopted to amend this Resolution under No. 206 on 10 / 04 / 2012, and therefore the amended expropriation decree was in the custody of the Presidency of the Cabinet after its signature by the Minister of Energy and Water. 

However, the dam project faced some obstacles due to the non approval of the Director General of Water Resources and Power to take reception of the preliminary studies from the consultant, which is a prerequisite condition for the completion of the detailed studies. Hereinafter, one of the most important reasons based on which the Director-General of the water and power resources based his decision :
 
On 21 / 5 / 2012, the German Institute for Geosciences and Raw Materials (BGR), examining the " protection of Jeita springs ", reported that the water of the river Nahr Ibrahim strongly leaks from the high presumptive lake to the basin of Jeita springs. The consultant in cooperation with the hydro-geological expert Dr. Behzad hakim denied this theory, because Nahr Ibrahim is fed with water from several springs flowing from its left bank, and therefore this water can not go out from the left bank outside the basin. It appeared that the German expert who presented the report has built his conclusions on incomplete geological data, and inaccurate way to measure the flow of water. 
To make sure that there is no leakage from the lake outside, expert Behzad hakim recommended to carry out a new surveys campaign forming the subject of a new third contract with “ Khatib and Alami “ approved by the Board of Directors in its resolution No. 233 on 1 / 11 / 2012. This contract, which amounted $ 694.262 million LBP, included the following items:
- Campaign for flow measurements on several sections of Nahr Ibrahim. This campaign was carried out and showed undeniably that the river flow increases th more we head down, and this reinforces the idea that there is no leakage from the basin outside. 
- Drilling a well in Sraita, to make a water color technique to insure the destination where water leaks from the upstream of the lake into the basin. The consultant began digging this well on 12 / 26 / 2012., 
- Drilling two wells on the axis of the dam, the first in Lassa and the second in Kartaba, to study thoroughly the water leakage through faults present in the dam’s area. The detailed study showed how to address these faults, especially the fault in the left bank, by an Injection curtain, still the pumping operations to be conducted on these two wells will allow to check the measurements of the injection curtain and the development of technical solutions necessary to address any leakage in the event of its presence. 
It should be noted that these surveys do not affect the detailed studies of the dam, and their intended purpose is making sure of some hydro-geological data for the area of the dam and the lake. 

2 - The second phase, which includes body of the dam and its ancillary facilities 

The detailed studies ended in November 2012, after a decision rendered by HE the Minister of Power and water resources ordering the consultant to follow up these studies, regardless of the position of the Director-General of the resources.
 
The consultant submitted the documents relating to the detailed studies in December 2012. After reviewing all the documents submitted by the consultant, and after holding several meetings in which all technical matters relating to the dam and its design, and the leakage of water from the banks of the lake were discussed, the Committee of Jannah dam requested the consultant to prepare the SOW and administrative Specifications of the second phase of the dam’s project. 

It is expected to launch the tender of the second phase of the dam on 15 / 02 / 2013 save to call international companies specialized in the construction of dams to participate in this tender, save to be classified of first category by the Ministry of Power and water resources in the section of dams, tunnels and mountain lakes. 
The bids opening session is expected to take place in mid-May 2013, save to evaluate the bids within two months from this date, and select the best bidder in mid-July 2013.
