| A biennial water rate survey conducted by the city of Ames shows Waterloo maintained its longtime status with the cheapest water bills of the state's 33 cities with a population of 10,000 or greater. The survey, conducted in September, compiles monthly water rates in each community based on 6,000 gallons of water usage, or normal household usage, each month. | |
