What percentage of treated water should enter the suds?

The correct choice is that 100% of treated water should enter the sustainable urban drainage systems (SUDS). SUDS are designed to mimic natural processes to manage surface water and improve water quality. By allowing all treated water to enter these systems, it facilitates processes such as infiltration, evaporation, and reuse, which align with sustainability goals and help in reducing flooding and pollution.

Using 100% of treated water in SUDS ensures that the maximum amount of runoff is effectively managed and reused, enhancing groundwater recharge and promoting biodiversity in urban environments. It reflects the commitment to optimizing water management practices, which are key in the Pearl Building Rating System to achieve sustainable performance in building design and construction. This approach maximizes the benefits of the treatments applied to the water, ensuring efficient and environmentally responsible use.
