One Clarions Industrial Wastewater Tanks are above-ground vessels used to hold, equalize, or stage industrial wastewater before treatment, discharge, or hauling. Exceeding EPA and AWWA requirements these tanks are an essential part of an industrial water treatment process, helping facilities manage variable flows, protect downstream systems, and maintain environmental compliance. Constructed from our bolted flat panel design, each tank is sized to fit your flow rate, chemical makeup, and site requirements. As part of a complete industrial water treatment solution, these tanks integrate with pretreatment, neutralization, and filtration systems to support safe, reliable plant operation.
Industrial Wastewater Tanks
Above-ground storage for equalization, pretreatment, and temporary containment. HDPE, FRP, lined steel, and bolted configurations.
Industrial-Grade Tanks for Wastewater Management
Who Uses Industrial Wastewater Tanks?
Environmental & Process Engineers
At mid-to-large manufacturers including food & beverage, chemical, metal finishing, and power generation facilities. These professionals specify capacity, materials, and controls to meet permits and ensure consistent compliance with discharge regulations.
Facilities & Maintenance Managers
At small-to-mid plants and logistics sites who need durable, quick-ship tanks to consolidate waste and reduce hauling costs. They value reliability, ease of maintenance, and solutions that minimize operational disruption.
EPC & Consulting Firms
Design-build partners who integrate storage and equalization into new or retrofit projects. They require stamped drawings, schedule certainty, and technical support to ensure seamless project execution.

Wastewater Tank Applications
- Equalization (EQ) & Surge: Smooth daily peaks and protect downstream treatment. Typical: 10,000–30,000 gal, duplex or triplex trains.
- Pretreatment & pH Neutralization: Batch/hold prior to neutralization or chemical dosing. FRP/HDPE preferred for acids/caustics; lined steel for elevated temps.
- Oily Water / Separator Skim: Hold separator effluent or skim liquids before handling. Add flame arrestor vents and spill containment as needed.
- Washdown & CIP Water: Capture sanitation and equipment wash flows for timed release or treatment. Popular: 5,000–15,000 gal HDPE/FRP.
- Storm Bypass / Turnaround Storage: Temporary capacity during outages or maintenance. Pair with rental-ready fittings and cam-lock manifolds.
- Sludge / Clarifier Overflow: Manage solids-bearing streams using lined steel or heavy-wall FRP with cleanouts, mixers, and sloped floors.
Wastewater Tank Resources & Regulations
Use these references to understand federal and state requirements that may apply to wastewater storage, equalization, and discharge.
- EPA Clean Water Act Overview : Federal framework for water quality. Discharges of pollutants from point sources to navigable waters generally require an NPDES permit.
- EPA State Program Contacts : Find state-level contacts and guidance. Local rules and permits can vary by state and municipality.
- AWWA Standards : Voluntary consensus standards used across water and wastewater projects for materials, design, and testing.
