Water Costs Less with Hydraulics

What some of the residents in our village don't understand is that our water's costs would significantly go down if we change our water service providers. The board of directors have been trying to explain this ever since but some don't just get it. They were probably confused (afraid) when the other company talked about hydraulics, hydraulic arms, etc. They thought having this would make our water's costs soar. What they don't understand is that operating and maintenance costs are lower with hydraulics, hence cheaper water. The board will be making a decision whether to switch or not. I hope they'll come up with a wiser decision.
