Little Rock Wastewater (LRW) provides wastewater collection and treatment services for the residents and businesses of Little Rock. Currently, LRW has 28 remote, unattended pump stations, two secondary treatment plants with another in the initial stages of construction, a maintenance facility, and an administration building. The collection system includes over 122 square miles containing approximately 1,314 miles of sewer lines. LRW currently employs 243 employees.

LRW serves the city with two secondary treatment facilities that discharge into the Arkansas River.

The Adam’s Field Treatment Facility is located near the airport and has the ability to treat up to 36 million gallons of wastewater a day and uses modern technological advances such as Odor Control Towers and Ultra Violet (UV) disinfection.

The Fourche Creek Treatment Facility is located near the port area of Little Rock and has the ability to treat up to 16 million gallons of wastewater a day. 90% of the energy used at the facility is obtained from recycled methane gas produced at the facility.

LRW is currently constructing a third treatment facility near Pinnacle Mountain, which will have the capacity to treat up to four million gallons of wastewater a day. This facility will utilize the most modern wastewater treatment technology, such as a tertiary treatment process, odor control towers and UV disinfection.
