General Information


New customers without a prior consumption history are charged a basic monthly rate of $16.20 and a one-time, non-refundable fee of $30.56. The monthly rate is based on the average water consumption used by all customers.  If you contact us following three complete months of service, we will be able to see a pattern of usage and determine if an adjustment should be made on your sewer charge.


Existing customers are charged based on the average water usage from November to April. In May, your residential sewer bill is re-averaged to determine the basic sewer rate for the next year.


How are bills calculated?  Bills consist of two parts (service charge & volume charge).  

Service Charge

(Based on meter size)

Meter SizeMonthly Charge

Most residential customers have a 5/8”meter.

Volume Charge
Residential $1.84 per ccf

For your information:
Each Ccf contains 748 gallons of water.

Sample Residential Sewer Bill
If a customer’s average water usage from Nov. to April is 10 Ccf or 7,480 gallons, their monthly sewer bill will read as follows:

$4.39 [Service charge]
$18.40 [Volume charge of 1.84 x 10]
$22.79 Total Amount


Why are sewer charges based on a six-month winter average? Answer: Fairness. This method more accurately reflects the household water usage which enters the sewer system. During the months of November through April, almost all of the water entering a residence goes down the drain and into the sewer system. During the summer more outside watering occurs (i.e. lawns, car washing, gardens or filling swimming pools) which does not enter the sewer system. (Normally, less water is used in the winter than in the summer so this billing method saves the customer money.)

Usage per household varies depending on the family size, appliances, and condition of the plumbing fixtures.  The average consumption for one (1) person is four (4) Ccf per month or 100 gallons of water per day.

Leaks in the winter could impact your sewer rates.  Adjustments can be made depending upon the type of problem, how long problem existed, proof of repair such as a plumber’s invoice or purchase receipts for supplies, and verification that the consumption has returned to normal range and levelized.  (Adjustments cannot be made beyond a 12 month period.) *Free Leak Detection kits are available.


Before the treatment of wastewater became a standard practice, the amount of waste being released into the environment was a real hazard – the source of many life threatening diseases and the cause of dangerous pollution.

Today, thanks to modern methods of collection and treatment practiced by facilities like Pine Bluff Wastewater Utility, we can all enjoy clean water and better health than ever before.

Collection of Wastewater:

Wastewater runs from homes and industries in Pine Bluff into our wastewater system. As the name implies, it is mostly water; only about .06% is waste material.

It is carried by the wastewater system to the wastewater treatment facility. Here it is cleaned in much the same way as nature cleans water. Pine Bluff Wastewater just speeds up the process so that water can be purified in about 100 days instead of months to years.

Our treatment plant uses a series of treatment stages to clean up water so that it can be safely released into the Arkansas River. There are two major steps:

Primary Treatment: 

First, debris such as tires, 2x4s, cans, etc., are separated from the water using screens. This primary treatment removes a portion of the pollutants.

Secondary Treatment:

After primary treatment, wastewater still contains solid materials and waste dissolved in the water. Under natural conditions, these substances would provide food for microscopic organisms – fungi, algae, and bacteria – that are an important part of life in a stream or lake.

Pine Bluff Wastewater Utility steps up this process in the secondary stage. Air is supplied to stimulate the growth of bacteria and other organisms that consume most of the waste material, up to 85 or 90 percent.

Towards the end of the treatment process, the organisms start to consume one another due to the lack of food. This is called endogenous respiration. The clean water is then disinfected to kill any remaining harmful bacteria and released in the Arkansas River.

From here, it will evaporate into the air and then condense into rain – then it will fall to earth, starting the water cycle all over again.
