Conn. Water and Sewer Rate Survey Released

Middletown, CT – Tighe & Bond published the results of its most recent Connecticut Water and Sewer Rate Survey. Since 1998, Tighe & Bond has gathered and published Connecticut water and sewer user rates data that municipal government, regional authorities and private water suppliers can use as a benchmarking tool for comparing their rates against other suppliers in the state.

One of the most commonly reported challenges facing water systems across Connecticut is aging infrastructure. A rate structure designed to provide sustainable revenue for operations and capital programs is critical to ensure reliable, safe drinking water and effective sewer and fire protection.

The survey, conducted across the state during 2019, includes typical annual homeowner water and sewer costs for most systems throughout Connecticut. It also provides information regarding rate structures and billing cycles. This can be particularly useful information when suppliers are considering adjustments to their current rates or rate structures.
