Right now, a significant majority of water and sewer costs are paid by ratepayers. Whether you are Baltimore's most or least wealthy resident, you essentially pay the same amount to use a gallon of water. But our country was built on a progressive system of taxation. Wealthier people pay a higher rate in income taxes and pay greater amounts in property taxes based on the value of their homes. These tax dollars then go to cities and states to take care of the basic functions of society, like first responders, schools, streets, libraries and many other services. Certainly, water, sanitation and flood control should belong in this category, too.
