There are lots of nonsensical stories like this circulating on social media right now. Water draw for datacenters can't turn tap water brown. That's a supply or piping issue.

Here's one link amongst many a quick Google search that explains how low system pressure from increased demand can cause discolored water. (Check out the section on municipal water supply disruptions) I live in new orleans and entire neighborhoods need to boil water in periods of high demand.
Your page: "This discoloration happens because of rust, dirt, or old pipes in your plumbing. Problems with the city water supply can also cause it."
We're saying the same thing. It's the responsibility of the water system to pump clean water to people. Customers actually using that service can't be blamed for the system's failure to deliver it, as the customers aren't actually making the water brown themselves.
That's a strawman, nobody is saying that the datacenters are directly turning the water brown. But if adding a single customer (the datacenters) causes the supply not being able to meet the demand and the water turns brown, then yes the datacenters was the cause. Saying it's a supply issue is like if I come to a party at your house and load all the drinks into my car and saying that there's no drinks left is a supply issue
