Volume Charges2014

In the sample bill shown above, the residential customer has a 0.75 inch water meter ($21.00) and an AWC of 5,000 gallons.  The customer used 5,000 gallons (or 5 tgal) of water during this given month, so all usage is charged at the block 1 rate ($4.00 * 5 tgal = $20.00).  Therefore, this customer’s total monthly water bill is $41.00.

Sewer Charges Calculation

All customers receiving sewer service from the City of Lubbock shall be billed at the following monthly base and volume rates.  Rates effective as of 1-1-2013.   (Ordinance 2012-O0100, sec. 17)

Note: Sprinkler meters are not charged for sewer service.


Sewer Base Charge

Residential sewer customers must know their History Based Consumption (HBC) in order to calculate their sewer bill.  The HBC is the average amount of water that a residential customer uses between November and February. This value will differ between customers. 

A residential customer’s HBC will be used year-round as the volume of wastewater produced.  Therefore, a residential customer will have the same sewer charge for 12-months.  HBC values are updated every March.

The HBC value is listed on the front of the second page of your LP&L bill.  See figure below.

Sewer Bill Example
Sewer Volume Charge

In the sample bill shown above, the residential customer has a 0.75 inch water meter ($14.00) and an HBC of 6,000 gallons, or 6 tgal ($2.25 * 6 tgal = $13.50).  Therefore, this customer’s total monthly sewer bill is $27.50.

Bill Calculation


To ensure that our customers are charged fairly, the City of Lubbock uses meters to measure water consumption. We routinely replace meters every 10 years to ensure their accuracy. Your meter is read monthly by a trained meter reader who uses a handheld computer. Our meters are read accurately, resulting in City of Lubbock's 99% meter reading accuracy rate. Even though we strive for perfection, on rare occasions a meter will be misread. If you ever have a question about your meter reading or your water bill, please call us at (806) 775-2509. We'll be happy to check it out for you. 

Sewer Use is Averaged 

Because it is not cost effective to meter residential sewer use, the City of Lubbock averages it. The City of Lubbock uses the average of your winter months (November, December, January and February) usage to determine your average sewer usage. This is thought to be the best time to average because customers water their lawns less in the winter. However, if a customer's current month's actual water use is less than the winter months' average, the customer's sewer bill is based on the actual water use.
