Stealth the bigger hidden cost for homeowners with well water is when that septic system must be replaced or a well has to go deeper if a aquifer level drops too low or other problems like when the start up capacitor burns out. BUT Juntjoo I have a question , if your water meter is way out near edge of street instead of say being inside your house who is responsible to maintain the line between the meter and your home ? ( you earlier made it sound as if your local water utility is a for profit company, If your water utility is owned by a city or county they are not there to make profits , they are supposed to collect enough to pay for treatment to make sure the water is potable and treatment again on the sewage end of things. SO I suggest you re focus your negative view of your public works dept and look into leak detection monitoring that you can install/ have installed on to the line between your home but right up close to the meter and use it to monitor for leaks in the future or consider relocating to a home that is serviced by its own onsite well and septic. ( lastly if your homes water line is not plastic maybe you should consider having it replaced with plastic so it can flex a bit if there are ground conditions like when soils shift )
