REGULATION:

Water Law 10-95 Updated to Law 36-15 Institutional

Institutionalization of the Supreme Council for Water and Climate Creation of river-basins agencies throughout the national territory Creation of provincial and prefectural committees of the Water Legal framework for desalination

Planning

National Plan for Water Plan on Integrated Management of Water Resources at the regional level

Protection:

Quantity: perimeter of protection and prohibition of groundwater Quality: protection against pollution

• Financial:

Introduction of the principle sampler-pays and polluter-pays

NATIONAL STRATEGY FOR WATER SECTOR DEVELOPMENT Water demand management and valorisation of water resources

Preservation and protection of water resources, natural and fragile areas

application of the legislative and institutional reforms

Management and development of water offer

MORROCAN WATER STRATEGY

Reduction vulnerability to natural water risk and adaptation to climate change

Upgrading information systems and capacity building

Mobilization of conventional water Conventional water 1,7 Billion m3/year

• 130 large dams with a total capacity of nearly 18 billion m3 • Thousands of boreholes and wells • 13 systems of water transfer: 1100 km and 210 m3/s

Mobilization of non conventional water

Non Conventional water 800 Millions m3/year • Desalination program

• Wastewater treatment and reuse program

• Rainfall capture

DAKHLA CASE Population: 100 000 inhab Main activities:

Nautical sports DAKHLA

Fishing

Breading

DAKHLA Technical Sheet Capacity

: 17 300 m3/d (55% to be desalted)

Process

: Reverse Osmosis

Intake

: 6 Boreholes

TDS

: 2,5 g/l

Physical/Chemical treatment (H2S, Fe removal)

Commissioning date : Dec 2015

A Complex raw water quality with many parameters exceeding drinkable water standards H2S, NH4, Fe, TDS, T°

Biological treatment (NH4 removal)

A complex process to remove all the exceeded parameters Membrane Treatment (TDS reduction)

TAN TAN CASE Population: 70 000 inhab Activities: Breading , Fishing, Potential tourism

Tan Tan

Tan Tan Technical sheet Capacity (1st phase)

: 9 000 m3/d.

Process

: Reverse Osmosis.

Required Power

: 5 MW.

Commissioning date

: 2014.

Electrical supply

: National grid.

Renewable energy could be the solution for reducing energy costs Morocco enjoys an important potential of renewable energies.

Desalination coupled to RE is feasible (feasibility study already done for MENA regions). A specific one is in Progress.

For economical reasons, this technique should be used for cogeneration of : Drinking Water, Electricity and Heat.
