Billing & Account Information

Wastewater Use is Estimated:

Because it is not cost effective to meter wastewater use, DWU estimates it. To estimate wastewater use, DWU uses your winter months average (the average of your water billed in December, January, February and March). 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 (wastewater) bill is based on the actual water use.

How Your Residential Winter Months Wastewater Average is Calculated:

Your monthly sewer charge is based on an average of your water use billed during the previous winter months (December, January, February and March) or your current month’s use, whichever is less

Billing:

Your water bill includes DWU's charges for water, wastewater (sewer) and a storm water quality fee. The bill also includes the City of Dallas Street and Sanitation Department's charge for removal of garbage, rubbish, brush and bulky items, etc. State law allows taxation on the sanitation fee. If you have a question about your water, wastewater or storm water quality charges, call DWU's Customer Service Division at (214) 651-1441. If you have a question about your sanitation fee, call Street and Sanitation Department's Customer Service at 670-8613.

Billing Cycle:

DWU has divided Dallas into 21 geographical areas -- one for each working day of the month. Where you live determines the date your meter is read, the date your bill is mailed and the date your payment is due.

Monthly Bills:

The monthly rate for water service includes a customer charge and a usage charge. The customer charge will always appear on your bill regardless of how much or how little water you use. It is a service charge that helps recover the cost of meter reading and maintaining the water distribution and wastewater collection systems. The water usage charge is for the amount of water you use during the month. The wastewater usage charge is based on an average of the amount of water you used during the previous winter months or your current month's water use, whichever is less. The best way to save money on your water bill is to conserve water.
