During January, VicWater wrote to EPA in relation to mandated Log Reduction Values (LRV) in the draft recycled water guidelines. At the suggestion of the Department of Health (DH), EPA inserted a mandated 1 LVR ‘operation target’ above the nationally endorsed LRV standard.
If adopted, this change would significantly increase capital and operational costs of recycled water schemes.
The letter follows a detailed technical submission in December, virtually all of which was incorporated into the latest draft of the guideline. Negotiations are continuing between VicWater, DELWP, EPA and DH.
