### sec.57 Quality standard for recycled water supplied for a dual reticulation system Recycled water supplied for a dual reticulation system must be class A+ recycled water. Also, recycled water supplied for a dual reticulation system must be tested to measure the turbidity of the water and the chlorine residual in the water at the frequency required under the management plan for the water. The recycled water must have— a turbidity of less than 2 NTU; and a chlorine residual of 0.5mg/L or more. In this section— chlorine residual means the amount of free chlorine remaining in water after the water has been treated with chlorine. dual reticulation system see the Water Supply (Safety and Reliability) Act 2008 , schedule 3 . free chlorine means chlorine in water that is not combined with any other chemical compound. NTU means nephelometric turbidity units. (sec.57-ssec.1) Recycled water supplied for a dual reticulation system must be class A+ recycled water.
