Integrated Constructed Wetlands for Water Quality Improvement
The integrated constructed wetland (ICW) concept has evolved from traditional considerations of constructed wetlands and is based on the holistic use of land embracing the explicit requirements for wetlands not just to improve water quality but also to demonstrate landscape fit (including physical and social landscapes) and biodiversity enhancement. Pioneered in Ireland, the ICW concept has pursued a paradigm shift through moving away from electro-mechanical treatment of wastewaters in favour of the utilisation of wetlands, and other integrated ecosystems, as natural water management infrastructure. This approach has demonstrated that the achievement of water quality objectives can be attained whilst delivering a range of ecosystem services, distributed more widely across a greater number of beneficiaries and stakeholders.
