Your Bill

How is the sewer bill figured?

One of the most common questions our users ask is: How do we figure out what they owe for sewer service? The following is an explanation of how we figure your bill.

Your sewer bill has at least two parts –

  • The base service availability fee
  • The water usage or volume charge


The base service availability fee covers the District's fixed costs. These include monthly expenses the District must pay in order to have the service available to you, such as debt payment, costs to keep the office open, administrative staffing expenses, billing and collection expenses and other fixed overhead costs.  The base service fee is a minimum fee and shall be charged for every commercial or residential unit connected to the Sewer District's main sewer line.

Pressurized systems cost more to operate and maintain than systems served by a gravity sewer line. The additional surcharge on pressurized systems covers the cost of replacing pumps, electrical controls and float switches, cleaning pump screens and pumping septic tanks and other maintenance. The surcharge varies depending on the type of pump and/or the location of the septic tank. The amount of the surcharge is determined by the type of pressurized system pump installed.  There is no surcharge on pressurized systems where the homeowner is responsible for the upkeep of the pump and/or septic tank.  

The water usage or volume charge covers the costs to collect and to treat the wastewater – costs such as operating the treatment facilities, cleaning the collection systems, repairing the facilities and sewer lines, lab work, payroll for the field crew and other operational and maintenance costs. The volume charge is the same for all rates and all types of systems.

The volume charge is applied to your average water usage found for your home or business.  Each spring, the Sewer District reviews the actual water usage reflected on your January, February and March water bill (note that commercial accounts and "snow bird" accounts will use a 12 month average instead of using these three winter months). These three months are averaged and this average is used until the water usage data is reviewed the following year. We assume that most of the water that comes out of your kitchen, bath and laundry room is going down the drain and into the sanitary sewer system for treatment.  We use winter months to determine your water usage average so you are not being charged for watering your lawn, washing your car or filling your pool in the summer. The annual water usage update takes effect on the June billing statement every year. If your bill increases on your June billing, your water usage went up from what was averaged in the previous winter. If your bill decreases, your average usage went down.


You can identify what rate applies to your home or business by looking at your sewer bill on the Boone Electric Statement. A list of rates follows:

  1. Rate A: Gravity System – systems with conventional gravity flow sewer mains. Download current rates and more info on Rate A >
  2. Rate B: STEP (Septic Tank Effluent Pump) pressurized systems with septic tanks within 50’ of a road or driveway. Download current rates and more info on Rate B >
  3. Rate C: STEP (Septic Tank Effluent Pump) pressurized systems that do not receive any additional services hence there is no surcharge. The homeowner is responsible for the upkeep of the pump and septic tank. Download current rates and more info on Rate C >
  4. Rate D: SDVG (Small Diameter Variable Grade) systems are gravity systems where each home has a septic tank that is connected to a collection system with small diameter pipes. Download current rates and more info on Rate D >
  5. Rate E: STEP (Septic Tank Effluent Pump) pressurized systems with septic tanks more than 50’ from a road or driveway. Download current rates and more info on Rate E >
  6. Rate F: Pressurized systems with grinder pumps. Download current rates and more info on Rate F >
  7. Rate G: Pressurized systems with grinder pumps that do not receive any additional services hence there is no surcharge. The homeowner is responsible for the upkeep of the pump and pump tank. Download current rates and more info on Rate G >
