A requested 22.7% increase in residential water rates for Aquarion customers is before the Connecticut Public Utilities Regulatory Authority.

A public hearing on the proposal will be held Tuesday, June 18, 6:30 p.m., in Fairfield at Fairfield Independence Hall, 725 Old Post Road.

About 1,000 homes and businesses in Wilton are on lines owned by Aquarion.

According to Aquarion, the new rates would add 26 cents a day, on average, to a local residential household bill. Aquarion says the increase will help the company to continue to invest in infrastructure to serve 625,000 residents in 47 state communities.

In March, the company filed an application with PURA for new water rates that, if approved, would become effective September 2013. The water company requested an 18.3% increase in water rates in the first year, as well as increases of 1.8% and 1.9% in the following two years. The increase may vary by area, according to the company. For more specific information on rates, customers may call Aquarion at 203-445-7310.

Customers are also welcome to provide comments on the application at the public hearing or in writing to PURA at 10 Franklin Square, New Britain, CT 06051, or by sending an email to PURA.executivesecretary@ct.gov. PURA asks that commenters refer to Docket Number 13-02-20 in any written or electronic correspondence.
