Resource or Project Abstract

The proposed research is to provide solutions to the problems of on-site wastewater treatment and disposal for single houses in rural areas, particularly in areas where the subsoil is of low permeability. This research proposal is divided into four main subprojects, two based upon field trials, one on GIS modelling and one review of international best practice. Six existing septic tank soakaway will be monitored to establish the degree of contamination to groundwater and/or surface water and to assess the extent of the effluent plume. Two of the sites with low permeability subosils will then have two separate infiltration systems in parallel - a drip system and a Low Presuure Pipe system - which will be assessed in the field. Two willow evapotranspiration systems will also be constructed and monitored for the duration of the project. Geospatial modelling metholdogies will be tailored to evaluate a series of different strategies for use by Local Authorities with respect to planning decisions and the treatment and disposal of wastewater effluent. Finally, reviews of water saving technologies and advanced treatment processes will be made, as well as advice on how to assess bedrock permeabilities beneath shallow areas of low permeabiilty subsoil. Guidance for retrofitting existing on-site systems if problematic Fact sheets with design guidelines for LPP and drip feed in different subsoil types Design Guidelines for willow evapotranspiration systems receiving on-site wastewater treatment in Ireland. Geospatial modelling methodology allowing LAs to compare different strategic scenarios for on-site wastewater treatment & disposal. Guidelines on the best method to use for determining bedrock permeability for different bedrocks beneath low permeability subsoils in Ireland Quantification of effluent reduction potential using water saving devices Synthesis of all work packages in a coherent report to the EPA which addresses the objectives of the project
