WSSC is hosting a meeting Aug. 12 at 7:30 p.m. The meeting will be held at the Prince George’s County RMS Building, room 308 located at 1400 McCormick Drive, Largo, Md. Proposed changes to customers’ bills will be discussed. The proposed changes are part of an effort to shift the billing system to a more modern, equitable and predictable approach to gathering revenue. Customers shouldn’t assume the changes will lead to higher bills. The proposal aims to lower future rate increases.
