Just install a water tank outside your house that won't allow water from your system to flow back into the municipal system. Use a float or level sensor in your tank to control a valve from their system to shut off their supply when you don't need it. They would have no need to inspect anything past the outdoor tank.
Actually now that you mention that, there should already be a check valve right by the water meter that prevents water from flowing back into the city water. As the meter is placed right where the city water comes into the house, they don’t need to know a damn thing about what I have going on inside. Thank you!

I was actually envisioning a giant four foot air gap between system to make the separation visually apparent.
