Wastewater treatment service is essential to community well-being for two very important reasons:

• Wastewater treatment service protects public health from disease-carrying bacteria and viruses
• Wastewater treatment service protects water quality for both drinking water and recreational purposes. 

The Town of Arlington currently treats waste and sewer water in a lagoon on Collierville-Arlington Road, north of Highway 70. This facility has the capacity to treat up to 1,000,000 gallons of wastewater per day.

The end product is discharged into the Loosahatchie River. Due to the steady growth experienced by Arlington in recent years, the administration is finalizing plans and generating funds to construct a new mechanical treatment facility which will have the capacity to handle the additional needs created by the continuing growth. This new facility, once complete, will be able to carry Arlington well into the 21st century.
