Effluent Dispersion Modelling is an essential tool in the management of water resources. Discharges into waterbodies are regulated by the EPA and under EU Directives in Ireland, and by Environment Agency / NIEA / SEPA in the UK.
In addition to Assimilative Capacity Assessment, catchment based modelling tools can be used to develop water quality modelling solutions, providing confidence that discharges to the surface water and marine environment will not be detrimental to the quality of the receiving waters.
Our experienced hydrodynamic modellers work with dischargers and regulators to provide clear guidance on the potential impact of effluent discharges on water quality. We can provide appropriate advice in relation to near field and far-field assessments, and suitable modelling approaches.
Our in-house expertise using a range of software including MIKE, Innovyze ICM and Tuflow allows us to carry out complex water quality modelling to inform:
- Environmental assessments through the planning process to allow evaluation of effects on designated sites (EIA, Habitat Regulations Assessment, Appropriate Assessment)
- IPPC permitting and compliance monitoring
- Applications for discharge consents / discharge licences for industrial and municipal wastewater
- Refinement of treatment processes to ensure regulatory compliance
Our consultants undertake effluent dispersion modelling for discharges to rivers, lakes, estuarine and coastal waterbodies. For discharges to groundwater please see Hydrogeological Risk Assessments.
