Southeastern Tank

What Southeastern Tank does

Southeastern Tank, Inc. is a privately held, Tennessee-based water infrastructure solutions provider founded in 1984, operating from Lebanon, TN with a chemical storage and distribution facility in Loretto, TN. The company operates four integrated business divisions under the Southeastern Tank umbrella: (1) liquid storage tank design, construction, and installation, including authorized Aquastore glass-fused-to-steel tanks, HydroTec epoxy-coated tanks, and Total Dynamic Storage integrated systems; (2) water treatment chemical supply and delivery through Solutions by SET, stocking disinfectants, oxidants, coagulants, pH adjusters, and corrosion control products from a 20,000+ sq. ft. facility; (3) cloud-based real-time monitoring and SCADA/telemetry through Signals by SET, offering iQ2 platform, iQ Pulse hardware, and integrations with AMI vendors Badger, Neptune, Sensus, and Master Meter over AT&T FirstNet; and (4) Southeastern Valve & Service providing Bermad hydraulic control valves and field services. The company sells through a dedicated regional sales manager model covering seven southeastern US states (Tennessee, Mississippi, Alabama, Louisiana, Georgia, North Carolina, South Carolina), employing query-based project pricing for tank construction and recurring/usage-based pricing for chemicals and monitoring services. Customers are primarily municipal water and wastewater utilities, with secondary segments in industrial process water, fire protection, and landfill leachate.

The company has completed 500+ tank installations over 40+ years and serves customers ranging from long-standing municipal relationships (Marshall County, TN for 36+ years) to industrial operators (CSM Bakery). Revenue streams mix one-time project-based tank construction, recurring chemical supply contracts, hardware-plus-service monitoring subscriptions, and fee-based repair/inspection/cleaning services. The firm is independently owned and management/family-controlled, with the Dowdy family in senior executive roles (CEO Dustin Dowdy, Operations Manager Chris Dowdy) and no disclosed institutional investors or private equity backing. In 2026 the company completed a corporate rebrand, elevating Signals and Solutions into standalone branded entities alongside the core tank and valve divisions.

Core offering

Southeastern Tank designs, distributes, and installs liquid storage tanks (Aquastore glass-fused-to-steel, HydroTec epoxy-coated, and Total Dynamic Storage integrated systems) for municipal water, wastewater, industrial, fire protection, and landfill leachate applications. The company additionally supplies water treatment chemicals, operates a cloud-based telemetry and SCADA monitoring platform (Signals by SET), and provides Bermad hydraulic control valve technology with field service support across the southeastern United States.

Product overview

Southeastern Tank is a comprehensive water infrastructure solutions provider operating a platform-plus-services model with three primary divisions: Southeastern Tank (liquid storage tanks), Signals (real-time monitoring/telemetry), and Solutions (chemical programs). The tank division offers three main tank technologies—Aquastore® glass-fused-to-steel, HydroTec™ TS/CS epoxy-coated steel, and Total Dynamic Storage® (TDS) integrated systems—serving potable water, wastewater, industrial, fire protection, and landfill leachate applications. The Signals division provides cloud-based cellular/Satellite telemetry and SCADA monitoring platforms (iQ2, iQ Pulse) integrated with AMI meter systems (Badger, Neptune, Sensus, Master Meter) via AT&T FirstNet. The Solutions division supplies water treatment chemicals (oxidants, coagulants, pH adjusters, corrosion inhibitors) along with Stenner metering pumps, HDPE storage tanks, and valve services using Bermad technology. Combined with installation, inspection, repair, cleaning, and water quality management services, the company delivers end-to-end lifecycle support for water and wastewater systems across the southeastern United States.
