Can we harvest RO reject water, in our rain water harvesting system? RO reject is approximately 180KL per month and is currently being disposed off by discharging in to the sewage disposal system. If the same can be used to recharge groundwater what are the norms to be followed / tests to be conducted? Is there any system that helps in the refinement of RO reject enabling it to be used in groundwater recharge?
