There are several categories of fees that the WPCA collects.
Usage Fees:

User fees are used for the operation of the WPCA and for processing wastewater in Danbury.  The usage fees have remained low throughout the decade of 2000-2008 at $268 per year per household, then at $300 per year for 2008-2010 and at $340 annually from Sept 2010 through August 2012. In 2012, the annual rate was set at $380. That rate lasted for 5 years. For the June 2017 billing, the rate increased to $420 per year or $210 per billing to cover the increasing cost of operations. That was an average increase of less than 2% per year over the previous eight years* [More…]

 Why the increase?

Fee increases are simply required to operate in the black. Brookfield sewer rates are at or below neighboring towns. The rate of $420/year per household was held for three years from 2017-2020. The current 2022 rate of $440 is still a good value at $1.20 per day, about half the price of a cup of coffee. This is a favorable rate compared to most neighboring towns. The rate is approved to increase to $460/year in 2022 and $480/year in 2023.

Beginning June 2017, Brookfield started to accumulate funds in anticipation of a significant Danbury Waste Treatment Plant upgrade as mandated by the EPA. That amounts to a surcharge of $80 per unit annually.

How Does the Brookfield Usage Rate Compare?

Brookfield does not meter water usage for sewer users. The charge for a homeowner is based on the typical home usage rate of about 100 gallons per day. A 2019 survey of CT Towns by Tighe&Bond reported annual use charges. The graph below is adapted from that report.  [Full Report …] This rate comparison study is conducted every 3-years.


Town *Rate 2019
Danbury *$312
New Milford$595

* Some towns, like Danbury, subsidize sewer operations with town funds. The sewer operation in Brookfield is a standalone operation funded only by sewer users.

* Beginning September 2012 the annual rate was set at $380 per unit, then increased to $420 per unit until December 2020. The annual rate is set at $440 in 2021; $460 in 2022 and $480 per unit per year in 2023. A household is one unit. Business and Schools are multiple units. Consequently, some properties pay more, as usage can be set to more than one unit. There is a rather complicated formula to determine the number of units of a property. This is outlined in the Rules and Regulations of the WPCA.

Note 1: The amount of the engineering and legal review fees depend on the complexity of the project and are put on deposit. Any excess is refunded and overage is billed.

Note 2: The Grand List Value (GLV) is the 70% value of a property as determined by the Tax Assessor.
