The 7,000 households in Carroll County that receive public water from Liberty Reservoir are expected to see a slight increase in the water and sewer bills.
The county is expected to adopt the new rates as part of its budget on Tuesday, May 28, said Roberta Windham, a county spokeswoman. New rates would take effect July 1.
Carroll County buys water from the Baltimore Department of Public Works, which announced Monday it will seek a 15 percent increase for city water and sewer customers.
In Carroll, the base quarterly water fees would increase from $6.75 to $7.34. Households that use between 10,000 and 30,000 gallons each quarter would see their water bill increase from $5.42 to $5.93.
Sewer rates also are expected to increase from a base rate of $9.66 per quarter to $10.45. Quarterly usage between 10,000 and 30,000 would go from $8.29 to $8.69.
