Face of water in Lebanon. Hope of peace

Discussion with Jaber Bassan, 69 years old, adviser with the Ministry for the Hydraulic and Electric Resources.

Summary of the first part of maintenance:

Civil war of 1975 to 1990

Annual precipitations:
840mm in 80 days left again in 8 months between September and May.
200mm for North and 1500mm in top of the mount Lebanon (valley of Bekaa).

Water report enough but:
1. Bad distribution in time
2. Bad distribution in the country

While simplifying, here the mechanism which makes of Lebanon a well sprinkled country but not everywhere:
- the dominant winds arrive from the Mediterranean by the West of Lebanon charged with water.
- When that they run up against the chain of the Lebanon go up (until 3000m of altitude), they must discharge from their moisture to be able to go up (thus rain before and on the assembly line).
- While going down again in the plain of Bekaa (1000m of altitude) they is reloaded in moisture (thus they take water around them).
- There are a second zone of increase with the assembly line of the Anti Lebanon parallel with the first (2000m of altitude) and thus a second zone of precipitations.
For this reason Syria is desert in the East of Lebanon

Hydrography:
17 permanent rivers.

About thirty stoppings adding up 251millions m3 including 220 for the only dam Qaraoun on Litani.

2000 seasonal sources of drinking water terrestrial and 60 underwater sources.


Supply water:
In 1970, 3000 individual and collective drillings are in activities; in 1997, the census on the level of the buildings showed that 45000 buildings are equipped with wells for which it is necessary to add drillings nonrelated to the buildings (irrigation, village, etc...). In their crushing majority these drillings are illegal.
12 stations of water treatments are operational
23% of the buildings are connected to no network in 1997.
11% of the land districts are connected to no network.
Leakage rate of the network 50% Price of m3 varies from 0,11 cents euro to 0,40 (Beirut) according to the offices of water. In France one pays 2,2 Euro per m3 In the Lebanese invoice the cost of purification is not included/understood and yet this price does not completely cover the real price of water (adduction, treatment, stopping, etc...)

Water treatment worn:
50% of the population are connected to sewerage systems (80% in urban zone, 25% in rural zone) rejected towards the sea and the rivers.
There are only 2 stations of pre-purification.
But 6 are under development and 5 in the course of invitation to tender. 13 secondary stations were carried out by ONG local communities. 87 outlets at sea (29 industrialists, 58 servants).

Water with the meter... and if there weren't?

Operation in the cities is simple, there is a gauge at each house. This gauge consists of a fixed opening of diameter. The pressure being always the same (in theory) volume delivered in one day amounts in m³ according to the gauge which one has (1m³ in general for the private individuals). This system of gauge is very practical for the offices of water, because it makes it possible to deliver the same quantity throughout the day. Thus a peak period ago. On the other hand for the users the system is very constraining. The pressure being weak, all the buildings of more than 3 stages must have a pump. Moreover the low flow does not allow to take a shower, it is thus necessary to equip all the buildings (and even the houses) with tanks put in general on the roof. These tanks make it possible to keep a pressure and a constant flow (by gravity) sufficient when it is wished. Actually the network of the town of Beirut undergoes water cuts regularly. It is thus necessary to have large a enough tank for the days when there is no water. See example of the management of water in a hotel (below)

Continuation of maintenance

HYdrotour: You spoke to us a few moments ago about the river El Kebir which delimits the border between the North of Lebanon and Syria. According to you it is an example of co-operation between two states on a significant problem of division of water?
Jaber Bassam: Yes! We started in 1998 at the time when I took my retirement and which I left the post of General manager. I then intervened in this file as institutional expert. At the beginning of the year 2002, the final project was ready and, as of April 20 of the same year, an agreement had made between the Syrian Minister for the irrigation and the Lebanese Minister for the hydraulic and electric resources. Only two months after, the agreement was ratified by the Lebanese Parliament and the assembly of the Syrian people.

"a stopping will be built by the two countries..."

HY: Can you summarize us the content of this agreement?
JB: Initially it would have to be specified that this agreement was built on the model of the convention of the United Nations on the laws of use of the international nonnavigable rivers.
We started by defining his annual throughput on the basis of data which we had in the two countries: 150 million m³ per annum.
60% were allocated to Syria and 40% in Lebanon that it is in dry or wet period. Each country has the right to use its quota at the place and the time that it chooses. A stopping of 70 million m³ will be built by the two countries, which will pay each one of it half. The good distribution of water, the management of the basin, as well as the construction of the stopping will be managed by a Joint Committee.


HY: How determined the quota of use?
JB: We based ourselves on the recommendations of UNO (Article 6 of convention) which define the following factors:
- Hydrogéographie, hydrogeology...
- social and economic Needs and needs for the population.
- existing and potential Use.
- Conservation and protection
- Presence of alternatives

"Syria A admitted that these two stoppings could have a negative impact downstream"

HY: Which were the great contributions of this agreement?
JB: The construction of the stopping, without any doubt! Indeed, Syria has already on its territory upstream of two stoppings of 35 million m³ each one, and it does not need really a third stopping. However to take into account article 7 of the International Convention, which mentions that there should not be harmful effect on behalf of one or the other country, Syria A admitted that these two stoppings could have a negative impact downstream, and thus accepted the construction of this one...


HY: And to conclude?
JB: The agreement on Nahr El Kebir is an excellent example of co-operation between two countries based on conventions of UNO. It shows that divergent interests for the use of divided water resources, can be harmonized and that peace on ground would be reached if good intentions guided the world.


HY: Thank you Jaber Bassam, thank you for this conclusion. We hope that one day it can adapt with your neighbor of the South: Israel.

The management of water in a hotel:

Summary of the discussion with Melhem Malkoun, General manager of Put of Gold, Beirut, Hamra district.


The Casa hotel of Gold has a capacity of 120 customers.
A customer consumes on average 1/2m3 per day. This holds account of the laundry, the kitchens, the maintenance and the consumption of the rooms. For that the hotel has 100m³ cisterns in the basements (dirty and clean water) and 40m³ on the roofs (water suitable for consumption, which goes down in the rooms by gravity). Normally the water of the city (measured with 60m3) should make it possible the hotel to be autonomous. But actually (and especially in summer), the water cuts are frequent and can lasted one day whole. The direction of the hotel thus set up a provisioning by tanker.
In order to ensure itself of the food safety of its customers, Put it of Gold made install a true station of water treatment in its basements.
The circuit is thus the following:
1. Water passes in a reversed osmosor who disencumbers it of the majority of the micro-organisms. In order to limited the losses which amounted to 50% (water which remained bad side of the membrane and was then not recoverable), Melhem Malkoun set up a system of recycling of this water and reduced the losses to 25%.
2. Water passes in a system of filters to the activated carbon which fix another fraction of bacteria and chemical.
3. Then a chlorination.
4. Lastly, to withdraw the chlorine taste, they carry out a dechloration.
By safety, an analysis of the quality of water is made each month.

The hotel also has a well which is seldom used, because water is increasingly brackish there. This results from the overexploitation of the ground water which, being emptied of its fresh water, is polluted by the very close sea water infiltrations. This irreversible phenomenon in the short run is increasingly frequent on the coast of Lebanon.
Here an interesting example of what must do a "rich" hotel to provide to its customers water necessary to her two or three daily showers. For this hotel the price of water covers all its direction.
