Frequently Asked Questions

Unit Charged

The residential Water Pollution Control Authority (WPCA) User Rate per Centum Cubic Feet (CCF) for Fiscal 2026-2027 is $6.883.  A single fixed residential Unit Charge of $34.00 per quarter is billed every resident with access to the sewer system. Residents not connected are not exempt from this cost. 

Measuring Consumption

The number of CCFs each dwelling generates is determined by the amount of water coming into the house. That consumption is measured by their water meters and billed quarterly. The consumption plus the Unit Charge determines the total sewer user bill. 

Example: Water consumption of 21 CCF multiplied $6.883 equals $144.543 plus the Unit Charge $34.00 equals $178.543 for the quarter. 

Estimated Cost

The estimated cost to Bridgeport for Sewage Treatment: $7,571,300 is based on an estimated consumption of 1,100,000 CCF.
