Monarch operates the water system for a small community in which I own a vacation rental property. First of all, we pay over $115/mo for basic water, plus additional for each 1000 gallons used. Despite paying this premium, we continually have water quality and water pressure issues. The system uses a pump to create pressure (rather than a water tower, which uses gravity). Several years ago the fail safe on the system failed and water pressure got so high that a number of homes were damaged when valves broke causing flooding. In my home the water heater pressure relief valve opened and flooded part of the home (The valve is rated at 110 psi. Normal pressure is about 50 psi). They refused to accept any responsibility for damages. Fortunately, my insurance company paid most of my damages.
Water quality is often so bad that is looks like muddy tea. See attached pics for some idea of what this is like. I have also found that complaining seems to fall on deaf ears. I guess they feel safe since we have no alternative to them.
