Goal: Major Risks for the Drinking Water Supply in the Greater Beirut Area are reduced by implementing measures to protect the groundwater contribution zone of the Jeita Spring from pollution.
1. Integration of water resources protection aspects into the investment planning and implementation process in the wastewater sector (geoscientific advice in wastewater sector) 2. Integration of water resources protection aspects into landuse planning (delineation of GW protection zones) 3. Collection and use of monitoring data concerning quality and quantity of water resources 4. Support of the partner institutions concerning the implementation of urgent protective measures
ProtectionProtectionProtection ofofof JeitaJeitaJeita SpringSpringSpring Jeita Spring is the main Source for Water Supply of Beirut
~ 75 % of Beirut‘s water comes from Jeita
Protection of Jeita Spring must be a national priority

• High rainfall (on average 1450 mm/a) • high level of karstification ► high infiltration / low retention capacity ► high spring discharge peaks during January to April (up to 60 m³/s), low flow during dry season (min. 1 m³/s) > water shortage in Oct/Dec • high GW flow velocity (up to 2,000 m/h) • rapid and uncontrolled urban expansion (approx. 200.000 inhabitants) ► severe deterioration of water quality over the past decades Main pollution sources: • wastewater (no WWTPs yet) • waste (often illegal disposal) • gas stations (54 inside GW catchment; 30 near catchment) • quarries (sandstone, cement, decoration stone) • Jeita – Dbaye water conveyor (up to 140 yrs old)

ProtectionProtectionProtection ofofof JeitaJeitaJeita SpringSpringSpring WEBMLWEBML Water Water Supply Supply System System – –what what should shouldbe be done done ? ?
30-50 Mio USD • Improve capture of Jeita spring
• Establish a new raw water conveyor (pipelines/new tunnel) with increased capacity (7 m³/s) (2 separate lines because one line could be damaged; redundancy)
• Establish dam with medium capacity (Daraya dam: 9 MCM) to overcome water shortages at end of dry season
• Do not allow illegal connections and illegal uses (“irrigation”)
• Increase capacity of treatment & improve treatment process
• Establish water quality monitoring & increase laboratory capacities
• Reduce water losses in Beirut
ProtectionProtectionProtection ofofof JeitaJeitaJeita SpringSpringSpring ConclusionsConclusions
The geological stucture and tectonics are virtually unknown ► a Geological Survey should be founded
The amount of groundwater available and the boundaries of GW catchments have never been studied. There is no institution that has the capacity to cover all aspects of water.
► a Water Resources Agency should be established to deal with - water resources monitoring (quality/quantity) - water resources assessments - water resources protection - demand management and allocation - planning of water projects
Wastewater is the main pollution source, but still no agency wants to deal with it. ► a National Wastewater Authority should be created, responsible for: - planning and implementation of WW projects - operating and maintaining WWTPs
