@Moon @genmaicha You need to look into why they want to ban barrels it’s more insidious than you think.

6mg/L target cannot be hit without claiming every bit of water possible to dilute the effluent. This is the less expensive alternative. That is why they are so violent about it. They must have their water.

Instead of dealing with the problem and removing it as it’s too costly they just dilute it.
