Disposal of copper ion

What is the most effective and cost effective way of getting rid of a huge amount (400 liters a month) of copper ion solution, while keeping the water supply safe too?

You didn't specify the copper concentration or what the other solution constituents, but two things come to mind.

First, if the copper is relatively pure, you could ship to a recycler. There are several that accept copper for processing into chemicals and animal feed supplements. Another approach is to install an electrowinning system to convert the copper to a recyclable, metallic form, however, this assumes that the electrolyte is something like sulfuric acid that would make a good plating solution.
