3472 Review of the Exmoor Mires Restoration Project Final Report The Exmoor Mire Restoration Project (EMRP) 2006-2010 aimed to restore the natural hydrology of degraded blanket bogs on Exmoor by blocking up the network of old drainage ditches. This project will shortly finish and funding has been secured from South West Water for a new and larger †˜Mires on the Moors†™ project which could potentially rewet up to 2,500 hectares of peatland on Exmoor. The EMRP Steering Group commissioned the Countryside and Community Research Institute (CCRI) to undertake an external and independent review of peatland restoration work on Exmoor to help guide future activity. The two main aims of the review were: i) to conduct a review of peatland restoration on Exmoor to date; and ii) to give guidance to the Steering Group on how best to proceed with peatland restoration, while furthering National Park purposes, and having regard to the economic and social well being of the local community.

3473 Artificial groundwater recharge practice in Cyprus: The Yermasoyia aquifer. The local experience with recharge activities with emphasis on Germasogeia aquifer is presented. These activities have been carried out in order to solve particular problems of augmenting groundwater supply rather than researching the technique itself.

3478 Attenuation capacity of a coastal aquifer under managed recharge by reclaimed wastewater Managed Aquifer Recharge (MAR) is becoming an increasingly attractive water management option, especially in semiarid areas. Nevertheless, field studies on the fate and transport of priority substances, heavy metals and pharmaceutical products within the recharged aquifer are rare. Based on the above, the objective of this project is to study the hydrological conditions of the coastal aquifer of Ezousa (Cyprus) and its ability to attenuate pollutants. The Ezousa riverbed is a locally important aquifer used for a MAR project where treated effluent from the Paphos Waste Water Treatment Plant is recharged into the aquifer through a number of artificial ponds along the riverbed. Additionally, groundwater is pumped for irrigation purposes from wells located nearby. The hydrological conditions of the area are unique due to the construction of the Kannaviou dam in 2005 that reduced natural recharge of the Ezousa aquifer significantly, inducing the saltwater intrusion phenomenon. A three-dimensional finite element model of the area was constructed using the FEFLOW software to simulate the groundwater flow conditions and transport of Phosphorous and cooper in the subsurface from the recharge process. The model was calibrated using hydraulic head and chemical data for the time period of 2002-2011. The groundwater model was coupled with a geochemical model PHREEQC attempting to evaluate nitrate and Copper processes. Inverse modeling calculation was used to determine sets of moles transfers of phases that are attributed to the water composition change in groundwater between the mixture of natural groundwater and reclaimed wastewater and the final water composition. © (2013) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

3479 Characterization of the Ezousas aquifer of SW Cyprus for storage recovery purposes using treated sewage effluent A hydrogeological characterization of the Ezousas alluvial aquifer, located in SW Cyprus, has been conducted to assess its suitability for groundwater recharge with 5 Mm3 per year of chlorinated disinfected tertiary treated sewage effluent from the Paphos Municipality Wastewater Treatment Plant. Results from a 3 year field study conducted to establish the regional groundwater regime and to define the aquifer hydrology are presented. Pumping and constant-head permeability tests were used to estimate the key hydraulic properties of the aquifer system. The storage capacity was assessed to be 4.2 Mm3. The bedrock of the aquifer, near the coast, was found to be some 40 m below sea level, thus indicating the potential for seawater intrusion. A monitoring programme consisting of recording piezometric heads and electrical conductivities was used to observe the position of the seawater†“freshwater interface, so that rates of abstraction and recharge could be determined, to maintain a stable interface. The quality of the treated sewage effluent, and of native and abstracted groundwater, was continuously assessed in terms of salinity, heavy metals, persistent organic compounds and microbiota, to optimize the quality of the downstream groundwater used for local irrigation.

The aim was first to rebuild a biotope which had disapeared in the urban area; architects became aware of the benefits that green roofs could provide on water retention only later, in 1989.

3486 Green potential of a constructed wetland with reed bed filters on a 172 ha urban project near Reims (France). Project evolution analysis A 172 ha town planning project has been developed near Reims (France) for the last five years. For one of the catchments of this area (72ha) a 15 000 m3 detention pond is being built, in a difficult hydrogeological context since ground water level may rise up to the natural ground. The characteristics of this detention pond have drastically changed along the design process: the first hypothesis were based upon a deep concrete tank, but a constructed wetland has finally been chosen. This paper deals with the constructed wetland characteristics itself on the ecological point of view (deepness, shape...). It also points the design process that allowed such an evolution, thanks to both the designer proposals and the public authority requirements Constructed wetland with reed bed filters near Reims, France

3492 An integrated approach towards assessing the feasibility of domestic rainwater harvesting in Malta This paper explores the potential of small scale domestic rainwater harvesting on the island of Malta by taking an integrated look at the physical, social, and economic environments. It explores the extent to which domestic rainwater harvesting has been forgotten despite the fact of it being embedded within Malta†™s history for centuries. The study closely examines the cost-effectiveness of this technology both at a local and national scale and teases out the hurdles that have brought about its rejection by means of residential and water professional interviews.

3493 Non Conventional Water Resources Programme in Malta (Alter Aqua) The Maltese Islands have limited freshwater resources and depend heavily on desalination. Therefore there is an evident need to mobilise non conventional Water Resources (NCWR) in order to secure water availability and facilitate sustainable development.
