Water and sewer service in Lowell is mostly provided by Springdale Water Utilities, with a small portion of northern Lowell receiving service from Rogers Water Utilities. Subdivisions in western Lowell operate on decentralized sewer systems due to a lack of available gravity sewer service.

Potable water for much of Northwest Arkansas is treated by Beaver Water District's water treatment plant, located in eastern Lowell near Beaver Lake. Wastewater is collected by gravity sewer and sent to a lift station near the Monroe Avenue exit on I-49. It is then pumped south, eventually being treated at the Springdale Wastewater Treatment Plant.
