� Haouz Groundwater Table heavily overexploited (150%, -2m/year)� Dams: “off the limits”
� Reduced capacity due to siltation (Lalla Takerkoust: only 30% of nominal capacity)
� New investments hampered by increasing marginal costs� Rocade transfer Canal (from the neighboring Oum er Rbia basin):
� Actual flow (125Mm3) less than half ‘Paper’ resource planning (350Mm3)� Domestic water uses now 60Mm3 vs. 40Mm3 planned (to the detriment of
irrigation)� Recently: extra allocation of 20Mm3 for golf greens� Irrigation = adjustment variable:
� got only 36% of the 310Mm3 ‘paper’ allocation over 1993-2005� In bad years, uses only 50% of water available
� Trend: OK for five years owing to Wirgane dam and Wastewater Reuse� More 100 to 600Mm3 needed by 2020 if tourism is to meet planned development�� => What are the options?=> What are the options?

� Even operating and maintenance costs were not alwaysassessed or estimated for lack of data
� Only in a few cases was it possible to estimate opportunity costs and externalities
� Still, ranking of water supply solutions based on cost/m3 is highly sensitive to those costs
� The most costly solutions are found to be: transfer from Massira and desalination
� The most cost-effective solutions are the WDM ones, i.e. water savings on existing infrastructure and networks
� The cost-effectiveness of the WW Re-use solution is dependent on accounting for the informal sector opportunity costs i.e. farmers making illegal use of used water for irrigation

� Findings to be weighted considering funding sources associated to different solutions:� Dams to be State-funded
� Transfer from Massira will be at ONEP’s expense as far as treated water is concerned
� Irrigation water saving investments are subsidized at a 80% rate
� Domestic water saving costs may not be fully born by users due to limits set to tariffs
� WW Re-use and desalination offer PPP opportunities
� => shifting from full cost to public expenditure requirement may be appropriate from a public decision-making perspective
� Other/new options still to be explored/developed: groundwater recharge, use of flooding water, conservation agriculture, law enforcement on water pumping, incentives to water saving, taxes on tourism activities, river/groundwater contracts, ITQs?

� Average VA (reflects current situation) instead of marginal VA (appropriate criterion for allocation choice) was used for comparison
� Tourism and (esp. smallholder) agriculture issues are not homogenous in nature-comparison is imbalanced, “unfair” from a social viewpoint
� Reverse thinking: what does the VA/m3 indicator not say?� Agriculture: indirect values (livestock rearing, processing of
agricultural products…), groundwater recharge, drainage, social value (employment), environmental amenities with impact on tourism
� Tourism: price rise => loss in purchasing power for local consumers, GHG emissions
