  LARGE BARRAGES REHABILITATION PROGRAM

1-  Purposes

The main aims of constructing and/or rehabilitation of the barrages since Mohamed Aly age until now are as follows:

1-  Distributing the surface water that comes directly through the river for irrigation purposes

2-  Enhancing the efficiency of the irrigation system

Taking into consideration improving the navigation through the River Nile, as well as, introducing an electrical energy by composing a hydro power plant into the barrage body if it is founded to be visible.

2-  Major Barrages constructed on the River Nile

•  ESNA BARRAGE

•  NAGA HAMMADY BARRAGE

•  ASSIUT BARRAGE

•  DELTA BARRAGES

•  ZIFTA BARRAGES

•  DAMIETTA DAM

•  IDFINA BARRAGE

3-  Responsibilities of The MWRI

1- Construction of all Barrages with the required adjacent structures, locks, bridges and hydropower stations on the Nile , Rayahat and major canals
2- Regular Maintenance and supervision over all hydraulic structures located on the Nile and Rayahat which include 11 major barrages on the Nile and its branches as well as 16 head regulators directly fed from the Nile

3- Control, Supervision and Operation of grand barrages which require a high level of quality control like New Esna Barrage

4- Feasibility and technical studies , designs for new projects and preparation of the required specifications and contracts.

c)-  New Tawfiky H.R. & Navigation Lock.

1-  New Naga Hammady Barrage and its Hydro Power Plant Project

The old barrage was constructed in 1930 and its additional Navigation Lock was constructed in the 1993. The New barrage, which is located 3.5 Km. D.S. from the old one, started in June 2002.

The Main Component of The Project

6-  MWRI Participation in Navigation Facilitation

Long time ago MWRI cooperated with the River Nile Transporting Authority in improving the navigation along the River Nile in both Technical and Financial sides.

Projects carried out by MWRI concerning navigation

a)-  Damietta Dam & Navigation Lock

b)-  Naga Hammady Additional Lock

c)-  New Delta Navigation Lock

d)-  Additional Esna Navigation Lock

1-  Damietta Dam & Navigation Lock

It was constructed to serve the river transportation through the Damietta branch from the river to the sea.

a)-  The end of construction: 1989.

b)-  Location: 222 Km distant from the Delta Barrages on Damietta branch at 12 Km from Mediterranean Sea

c)-  Total cost: 14 Million L.E. & 10.50 Million USD.

d)-  Main component :

Navigation Lock: 17 X 150 meters

Spillway: 5 pays, each is 5.25 m wide.

2-  Naga Hammady Additional Navigation Lock

a)-  The end of construction: 1993.

b)-  Location: at the left bank of the current barrage 354 Km D.S. of Aswan Dam

c)-  Total cost: 35 Million L.E

d)-  Main component :

Navigation Lock: 17 X 150 meters with minimum draft 3 meters.

3-  New Delta Navigation Lock

Under the spot of enhancing the efficiency of the navigation & transportation through the River Nile, it was essential to think about constructing a new modern navigation lock to help with the other variant transporting facilities (the rail way and the highway), also with the purpose of upgrading the river navigation line between Damietta Port and Cairo through the Damietta branch.

a)-  The construction period: 1996-2003.

b)-  Location: 980 Km. D.S. from Aswan Dam at the beginning of Damietta branch.

c)-  Total cost: 80 Million L.E

d)-  Main component:

Navigation Lock: 17 X 180 meters

 

4-  Esna Additional Navigation Lock project

Why additional lock at Esna ?

1-  More than 250 floating hotels are running now between Luxor and Aswan , (there were only 40 floating hotels at the time of construction of the New Esna barrage).

2-  More than 100 navigation units pass through Esna navigation lock daily in the winter.

3-  The long waiting time especially at Sundays and Thursdays all the year especially at the winter

4-  The essential rotational maintenance schedule for the current lock (twice a year)

 

For all the aforementioned reasons, it was a must to think about constructing a

new navigation lock in order to be dealing with the government policies concerning improvement of the industrial, exporting, transporting and tourism aspects.

 

a)-  Construction period: from mid 2002 to the end of 2004

b)-  Location: at the left bank of the current New Esna barrage, 160 Km from Aswan Dam

c)-  Total cost: 160 Million L.E

d)-  Main component:

Navigation Lock: 17 X 160 meters with minimum draft 3 meters.

Esna Additional Navigation Lock project

7-  MWRI Maintenance of The Navigation Locks

Maintenance of the major barrages and main regulators is one of the MWRI responsibilities which include the following:

1-  The annual rotational maintenance schedule for critical major barrages, for example Esna new lock and Assuit Lock

2-  Non-rotational maintenance as Idfina Lock, Zifta Lock and other regulators built on the main canals fed directly from the River Nile.
