On the surface, a reformulation of water and sewer rates seems about as exciting as studying for an algebra test. But for county and city residents alike, the decision of an arbitration panel to refigure the way the city totes up water charges to its county customers is an important political statement.
For years one of the minor benefits of living in Baltimore County has been that water rates are lower there than in the city -- despite the fact that the two jurisdictions draw water from the same sources. The three reservoirs that serve people in areas as disparate as Union Square and Hunt Valley are located in the county, but they are run by the city, which is supposed to provide county residents with water at cost. The city, however, has been using an outdated formula to calculate costs. As a result, county residents pay too little, while city residents pay too much.
