So far, only about 1% of the British electorate has registered an interest in having a vote on channeling water management away from dumping effluent for profit and instead into public ownership for health.
Perhaps we can bump the numbers a bit, at least to the point where how not to enshittify what we drink and cook with might be debated by MPs?

Petition: Hold a referendum to bring the water industry into public ownership
Hold a binding national referendum on whether the water industry should be returned to public ownership. Water is a basic human necessity; we believe our privatised system has failed, so the public should decide who owns and controls it.
