MARSOL Demonstrating Managed Aquifer Recharge as a Solution to Water Scarcity and Drought
MAR & SAT-MAR IN SOME EUROPEAN MEDITERRANEAN COUNTRIES: SCENERY ADVANCES CONDUCTED ALONG By: Dr. Enrique Fernández Escalante MARSOL PROJECT Dr. Christoph Schüth
Increasind number and intensity of dry periods (Palmer Drought Severety Index*)
Decline of the available water resources in the Mediterranean arc of up to 50% by 2100 !
* Determines aridity from precipitation and temperature information, especially for long-term prediction

MARSOL Demonstrating Managed Aquifer Recharge as a Solution to Water Scarcity and Drought (FP7-Env-2013-Water-Inno-Demo) Start: 12.2013
Duration: 3 years
EU Contribution: 5.2 Mio €
The main objective of MARSOL is to demonstrate that MAR is a sound, safe and sustainable strategy that can be applied with great confidence. With this, MARSOL aims to stimulate the use of reclaimed water and other alternative water sources in MAR and to optimize WRM through storage of excess water to be recovered in times of shortage or by influencing gradients.

Managed Aquifer Recharge (MAR) Plot of hazard concentration on a transect through the aquifer from recharge zone to recovery well. It shows that an observation well on the perimeter of the predetermined attenuation zone would verify that the required attenuation is achieved within the zone.

MARSOL – 1-Lavrion, Greece Investigation and Monitoring WP Leaders
Major goals Lavrion. Main advances in the design of pretreatment tanks in WWTP and monitoring/prospecting techniques including telecommunications.
MARSOL – 2-Algarve, Portugal Modeling WP Leaders
LNEC
Major goals Algarve. Use of hose spillways, gravel filters and effect of leaving the vegetation growing up in the infiltration ponds, in order to increase the infiltration rate.
IWW/TUDa/NTUA/Eydap
MARSOL – 3-Arenales, Spain Technical solutions and benchmarking WP leaders Major goals Arenales. Advances and recommendations in the design of the slopes and bottom of the infiltration ponds and channels, stagnation structures for pretreatment, passive MAR systems with zero consumption of energy, studies and elements to avoid gas clogging and to enhance the air trapped into the aquifer, use of biofilters for purification in itinere and proposal of “triplets” schemes to improve the MAR water quality and reduce the Total Dissolved Oxygen (TDO) in the aquifer; inverse RBF, examples for multifunction e.g. “do not close a well, reuse it”. The most remarkable has been the active intervention and training of local farmers in the management.

MARSOL – Llobregat river, Spain An reactive layer located at the bottom of an infiltration pond to enhance the degradation of certain contaminants. Sulfameth oxazole
Diazonium salt
Diazonium salt
4-nitro sulfamethoxa zole
Mechanism degradation of SMX under denitrifying conditions
Major goals
Llobregat. Design of organic reactive layers, unsaturated zone monitoring techniques and algae removal
MARSOL – 5-Brenta, Italy Economic feasibility WP leaders
Major goals Brenta. Deployment of structures to achieve a laminar flow in MAR canals and the exemplar internal organizational structure for the Watching and Control Programs.
MARSOL – 6-Serchio, Italy River Bank filtration (RBF scheme)
Major goals Serchio. Use of Disinfection By Products (DBPs) related to River Bank Filtration (RBF) activities; automation and monitoring at both banks of the river.
MARSOL – 7-Menashe, Israel Desalinated sea water - Israel 3 desalination plants currently operating, by 2014 two more will start operation • Desalination plants built under build-operate-transfer (BOT) contracts • Less dry periods during the last years Production of an increasing amount of excess water. Water authorities aim at seasonal storage as well as aquifer storage recovery (ASR) of large volumes of these surpluses in the adjacent coastal aquifer via artificial recharge. Techniques include infiltration ponds and injection wells
Major goals Conjunctive use of water from different origins for MAR and its most appropriate management, advanced techniques to reduce the TDO concentration, advances in DBPs, artificial barriers and automation of management elements (gates, spillways…)
MARSOL – 8-Malta South Treated waste water - Malta A floating lens of freshwater in direct contact to seawater. Due to agricultural water abstraction incrasing problems with seawater intrusion. Availability of large quantities of waste water effluent available from a nearby treatment plant. Water used for irrigation, but a surplus is available
Major goals (i) combat sweater intrusion by creating a hydraulic barrier (ii) increase availability of freshwater in the coastal aquifer Malta South. Development of a proper design for wells in saline seawater intrusion barriers, closed circuit from a WWTP to injection boreholes, new proposal to improve the regulations related to MAR.

MARSOL Workshops and Joint Activities
Synergies with other EU Projects Joint Workshop with DEMEAU Tel Aviv, December 03 – 04, 2014
Discussion on the formation of a MAR/SAT expert forum The Action Group on water (EIP – European Innovation Partnership) will be used as a platform.
Joint Workshop with FREEWAT Pisa, March 21, 2015
Discussion on the formation of a MAR/SAT expert forum The Action Group on water (EIP – European Innovation Partnership) will be used as a platform.
MAR to MARKET Action Group, European Innovation Partnership (EIP) The aim is to speed up innovations that contribute to solving societal challenges, enhance Europe's competitiveness and contribute to job creation and economic growth. EIPs help to pool expertise and resources by bringing together public and private actors at EU, national and regional level, combining supply- and demand-side measures.
Coordinated by LNEC and TRAGSA, 36 Partners
MAR to MAR-ket ¿How to involve industry in water management & in MAR technique?
Industry must be aware that much of their future is linked to GW: – – – –
Water efficiency linked to a bigger productivity and savings Guarantee for sustainability and permanence Lower “water foot-print impacts” Huge potential to convert MAR into job opportunity creation (economic aspect)
