Read the passage carefully and evaluate the statement below:
Under the Municipal Industrial Water Recycling Mandate, all manufacturing units operating within designated urban industrial zones must source at least 40% of their non-potable operational water from municipal recycling facilities. However, manufacturing units that have installed certified on-site zero-liquid-discharge (ZLD) systems are fully exempt from this municipal sourcing requirement, provided their ZLD systems process 100% of their internal wastewater.
Statement: A manufacturing unit located in a designated urban industrial zone that processes all of its internal wastewater using a certified on-site zero-liquid-discharge system is legally required to purchase at least 40% of its non-potable water from municipal recycling facilities.
