Rates Information
Building customer value
We base our rates on the costs of treating and delivering water to our customers. Rates for service may vary based on your area, and if metered, the size of the water meter (basic service charge) and usage. In Connecticut and New Hampshire, the basic service is rendered per-diem so will change depending on the amount of days in the bill period.

Water Revenue Adjustment (WRA)
The WRA ensures that water utilities do not over-collect or under-collect the revenues that were approved in rates by the Public Utilities Regulatory Authority (“PURA”). The WRA is determined annually and will result in either a charge or
credit on customers’ bills based on actual revenues collected in the prior year. Effective April 1, 2024, the WRA credit is 0.29% and applies to all customers. The WRA credit percentage is applied to the total current service and usage charges
on your water bill.
Water Infrastructure and Conservation Adjustment (excluding Valley Water System) (WICA)
What is WICA?
In 2007, the Connecticut Legislature approved a WICA bill surcharge to cover the replacement of water distribution system pipes and related infrastructure that have either reached the end of their useful life or are negatively affecting water quality
or service reliability. WICA helps to facilitate more timely replacements of aging infrastructure, such as old or problematic water mains, valves that manage the flow of water through the mains, Aquarion-owned fire hydrants, meters and leak-detection
equipment. The WICA surcharge is applied to the total current service and usage charges on your water bill.
What are the benefits of WICA?
The benefits of WICA to our customers are enhanced quality and reliability. Improving our infrastructure enables us to improve our service and delivery.
How much is the surcharge?
The WICA surcharge is made up of two components subject to PURA’s authorization: a base surcharge and an annual reconciliation charge or credit. Effective July 31, 2024, the total WICA surcharge is 0.17% comprised of a base surcharge of 0% and the
2023 annual reconciliation charge of 0.17%. The legislation limits the base surcharge increase to 5.0% in any given year and 10.0% overall between full rate cases. Additionally, there must be at least six months between base surcharge changes. The
reconciliation charge or credit is effective annually on April 1.
