Sustainable Drainage Systems (SuDS), green infrastructure and nature-based solutions are actively promoted in both new developments and public realm projects across the County, including the Tallaght area. These measures include rain gardens, swales, wetlands, attenuation areas, permeable paving, tree pits and enhanced planting, all of which help reduce surface water flood risk, improve water quality, support biodiversity and enhance the local environment.

To support wider implementation, the SDCC Sustainable Drainage (SuDS) Design and Evaluation Guide has been published to encourage the integration of SuDS measures into developments and public infrastructure projects. The Guide provides practical guidance on the delivery of nature-based drainage solutions and promotes best practice in sustainable surface water management.

These principles are already being incorporated into a range of projects. A notable example is the redevelopment of Bohernabreena Cemetery, which includes several SuDS measures designed to retain, treat and slowly release surface water while also enhancing biodiversity. Sustainable drainage and surface water attenuation measures have also been incorporated into other projects, including the recently developed pitches at Killinarden Park and Jobstown Park.

Rain gardens, tree pits, sustainable drainage features and other green infrastructure measures can play an important role in addressing surface water flooding while delivering wider environmental benefits. Opportunities to incorporate such measures are considered as part of the design and delivery of new projects and the upgrading of existing public spaces, subject to site suitability, technical requirements and available resources.

The use of SuDS and nature-based solutions will continue to be expanded where feasible as part of broader commitments to climate adaptation, biodiversity enhancement, sustainable water management and the creation of greener, healthier and more resilient communities across Tallaght and the wider County.
