How to Save on Wastewater Treatment Chemical Storage Costs

Save on Wastewater Treatment Chemical Storage Costs

It comes as no surprise that a new wastewater treatment plant can cost hundreds of millions of dollars. Upgrading a plant can cost several million dollars as well. Yet, the chemical storage tanks that go into those plants are one of the least expensive items ranging from $1,000 to $40,000 each depending on the size and chemical configuration. That’s just a drop in the bucket (so to speak) of the total project cost.

As a result, the need for chemical storage often is overlooked or added on at the last minute, with little thought and planning. Project planners know they’ll need a tank, but more time is invested elsewhere—on the pumps or mixers, or other equipment.

And that can be an issue.

Chemical Storage Is a Priority for Wastewater Treatment

Poly Processing Tanks

All too often facility planners make late-game decisions about chemical storage when equating cost with importance. As a result, they end up choosing a tank that fits the already-designed space, rather than designing a tank for their specific needs and planning a space around that. The result is a non-ideal storage solution that negatively impacts the functioning of the wastewater treatment plant.

Although chemical storage tanks make up a small percentage of the cost of a wastewater treatment facility, they occupy a significant portion of its importance. A chemical tank is one of the most important systems in a treatment plant because if the tank fails or stops functioning, there will be no chemical for the facility. All the pumps and other equipment will also stop functioning because they won’t have any chemical.

Another reason project planners end up with non-ideal tank solutions is based on budget. You want to cut costs wherever you can. At Poly Processing, we understand the need for smart spending. That’s why we’ll make sure you get the greatest value for your dollar.

Get the Best Chemical Storage for Your Dollar

The goal of every treatment plant project should be achieving the greatest useful life possible for the money you spend. We build each tank for a particular chemical and application to give our customers the greatest life expectancy.

Our tanks are designed for specific uses, chemicals, and industries to increase your tank’s longevity and greatest performance possible out of your tanks. You’ll get everything you need and nothing you don’t—which means you’re not paying for features that don’t fit your requirements.

For wastewater treatment applications, we offer three innovative tank solutions to address your needs:

IMFO System


Tank maintenance can be a challenge with many chemicals. Which is why we developed the Integrally Molded Flanged Outlet® or IMFO system to minimize the hazards of traditional maintenance. With the IMFO system, the flange location is at the bottom sidewall of the tank for full drainage. Because it’s molded as an integral component of the tank, it eliminates stress and the opportunity for leaks at the flange.


Our SAFE-Tank is a crosslinked polyethylene double wall containment system. This “tank-within-a-tank” keeps contaminants secure in the case of a leak, avoiding the damaging of equipment, loss of chemical, or injury to employees in the event of a spill. It also keeps the interstitial space dry so that rainwater will not set off leak detectors.


Poly Processing’s exclusive OR-1000 system was specifically designed to address the aggressive oxidation effects of sodium hypochlorite, sulfuric acid, and hydrochloric acid by adding a chemical barrier between the tank and the chemical. OR-1000’s inner surface is made of medium-density polyethylene, specifically formulated to resist oxidation. Its outer surface is made of cross-linked polyethylene (XLPE) for superior strength. The two surfaces are molecularly bound together, creating a truly seamless bond between the XLPE and the inner surface.

Poly Processing understands the unique needs of wastewater treatment facilities, and we can provide maximum performance while keeping costs low.
