Paying For Water

In another thread, someone posted that all SUN RV Resorts are installing water meters so it must be a corporate decision rather than an individual park having increased water expense issues. I have no problem paying for what I use but I just don't like it when park owners make money on my use too. For instance, I looked at staying at two RV parks that were in the same municipality. Right next door to each other actually. One charges .10/kWh for electricity and the other park charges .14/kWh The Municipality has to be charging the same price to the Park owners so why the difference in cost to the people visiting the park? The same can happen for water too. I guess one can argue that one park may have installed new equipment and has to pay for it while the other park is using old equipment already paid off but I doubt it. It's more likely an unethical park owner making money where he shouldn't be.
