I- GENERAL INTRODUCTION TO ALGERIA

II- WATER POTENTIAL IN ALGERIA

The Water potential resources in Algeria is estimated to 18 Billion cubic meter

by year divided by area :

North 12,5 B.M3/An :

10.0 B.M3 Flowing

2.5 B.M3 underground resources

South 5,5 B.M3/An :

II- PARK WATER IN ALGERIA

The water production facilities in Algeria are diversified across regions and the

existing water potential :

1- Conventional water :

Groundwater Resources: Renewable and Fossil Superficial resources : Dams

2- No Conventional water

Seawater desalination

Wastewater reuse for irrigation.

Recently, the exploitation of fossil groundwater sources has taken a different scale to meet the demand of drink water in the southern regions. Example du transfer Ain Salah / Tamanrasset :

48 drilling,

750 km x 2 lines,

six pumping station ,

Demineralization station with capacity for 100.000 m³/d

Conventional water - Underground sources-

Renewable groundwater was essential water resource for drink water and irrigation in Algeria before exhaustion caused by : Aridity; Overexploitation of aquifers, proliferation of illegal drilling,

More than 70.000 drilling operation.

II- PARK WATER IN ALGERIA

Currently, the Algerian’s Dams park consists of 70 Dams with storage capacity

more or less of 7.4 billion meter cubic.

In 2017, after the completion of ongoing

projects, the park will reach 84 Dams with storage

capacity of 8.4 billion meter cubic.

Example :

Beni Haroune is the famous in Algeria with

1 Billion Meter cubic of capacity. (Realized by Grupo ACS)

II- PARK WATER IN ALGERIA

Conventional water - flowing sources-

Currently 102 wastewater reuse plants are in operation in Algeria with a total

processing capacity of 350 Million cubic meter/ year.

After the completion of ongoing projects, the number of sewage

treatment plant will reach 278 units for a total capacity of 1.2 bM3/ year.

Example :

EL KERMA plant in Oran :

- Capacity : 270.000 M3 /d

- Destined to Irrigation

Water exclusively for Irrigation

No Conventional Water - Wastewater reuse -

II- PARK WATER IN ALGERIA

WEX : February 29th to March 2nd 2016

Following the drought beginning 2000, the option of desalination has become a necessity in Algeria, especially in the West.

Algeria adopted two types of seawater desalination programs:

1- Installation of small plant capacity 2500-5000 M3/d since 2000 2- Built plant desalination with capacity more than 100.000 M3/d since 2005

Desalination plant park consists : - 23 small plant with a total capacity: 67 500 M3/d - 11 desalination plant with a total capacity of 2.3 M.M3 / d

Destined exclusivity to drinkable water

IV- Positive Impact of Seawater Plant in the Area

IMPACT IN AGRICULTURE ACTIVITY :

Indirectly, the plant have a positive impact on the Agriculture Sector .

HOW ???

1)- Using DAM’S water just for irrigation;

2)- Decision to invest in wastewater reuse for irrigation :

- Actually, commissioning 03 wastewater reuse plants in the

Area, and 03 others plants are in construction.

Objectif to reach :

13 MM3 / year for 1.300 h perimeter of irrigation

IV- Positive Impact of Seawater Plant in the Area

The desalination plant is actively involved in university

education in the west of Algeria.

HOW ???

1. Students of different specialties do their practical

internships at the plant

2. Signed an agreement with the Oran’s Engineer School to

create new specialties of engineer in Sea Water

Desalination .

3. Sponsor relationship between Oran's Engineer School

and Alicante’s university for studies the brine

THE FIRST PROMOTION OF DESALINATION ENGENNER WILL

BE OUTPUT THIS YEAR
