Some opportunities exist to increase water abstraction charges, which do not cover abstraction costs and are currently regulated by the Regulatory Office for Network Industries (MoE, 2010c). The challenge will be to prioritise and phase investments over time to focus on areas with the best cost-benefit ratio and the highest positive impact on water resources. The classification of the whole of Slovakia as a “sensitive” area under the Urban Wastewater Treatment Directive should be reconsidered, with a view to prioritising the most sensitive areas.
