I propose to take Questions Nos. 161 and 162 together.
I refer to the reply to Question No. 280 of 12 November 2013 which sets out the arrangements currently in place to encourage water efficiency in the built environment through the deployment of sustainable water systems, including rainwater harvesting systems and grey water recycling systems.
By referencing such systems in the building code, as has been done, my Department enables such systems, where used, to be designed and constructed in a safe and responsible manner and in accordance with the best available national and international guidance.
