As far as barriers, better to know where they are and how big they are now so you know exactly how high the metaphorical ladder you need has to be. All municipalities have water purveyors of some sort, but you’re right in that they’ll likely be less focused on conservation. They won’t however be less focused on protection and they may still have beneficial use projects. Also that’s not inherently bad news for you - it means a likely lower barrier to entry.
Anyways best of luck.
I realize this is a meme, but isn’t it mostly linked to how many men died in wars last century, which disproportionately skews the numbers?
