City of Del Rio says their utility department reads this meter monthly

Picture taken today of our water meter encrusted in dirt. Does anyone believe that this is one month’s dirt accumulated between readings? Months to years and coincidentally our bill suddenly jumped from the mid $60s to $90 for one month. Something very rotten is going on at city hall and many poor people are being taken advantage of. Is the city overcharging us to pay for their airline or for Laughlin Air Force Base’s absurdly low water rate?
