Evaluating Your Containment Costs: SAFE-Tanks vs Concrete Secondary Containment

Secondary Containment Costs

Secondary containment systems are recommended safeguards that can prevent costly damage to equipment and risk to employees if a primary storage vessel is breached.

There are several secondary containment options with varying costs, and concrete containment is a popular industry standard. But you may be surprised when you compare the true costs of a poured in place concrete system to Poly Processing’s sophisticated, integrated tank containment system, the SAFE-Tank®.

The True Cost of Concrete Containment

Many companies only consider the initial costs of a concrete secondary containment system, but there are ongoing costs and maintenance costs to consider as well. Here are a few factors you should consider before purchasing a concrete containment.

Multiple Containment Areas

If you’re storing various chemicals—especially acids and bases—you’ll need separate containment areas for each type of chemical. This prevents the possibility of a hazardous reaction if two leaks occur at the same time. While it adds a layer of protection, it also adds costs, square footage, and complications. Not only do you need to invest more, financially, but you also need to have adequate space for containment. And multiple containment areas means more man-hours for maintenance.

Cost of Concrete

Concrete can cost up to $12 per gallon or more, depending on the type of coating that’s used. Since a secondary containment tank must be able to hold 110% to 120% of the primary tank, just the secondary containment for a 1000-gallon tank could cost upwards of $12,000 or more. That does not even factor in the cost of the primary tank.

Coating and Maintenance

The inside of the concrete containment must be coated to keep chemicals from etching through the concrete. If etching occurs, you may need to repair or re-line the concrete system.

Even functioning concrete containers need to be recoated on a regular basis. Weathering from rainwater and exposure to the elements eventually wears out the coating. This process involves entering the containment area and thoroughly cleaning it, and applying a new barrier to the concrete. It’s an involved process that requires project management, proper staffing, and budgeting.

Leak Detection

Concrete containment areas normally require leak detection in the interstitial space to monitor the integrity of the storage unit at all times. However, sensors in the concrete containers can get wet due to rainwater, and signal a false positive.

Chemical Spills

If a spill does occur into a concrete secondary containment, in most cases you won’t be able to recover the chemical and reuse it. The chemical will become contaminated and you will need to:

  • Remove or haul away the spilled chemical
  • Purchase a replacement supply of chemical
  • Repair, recoat, or replace the concrete container

SAFE-Tanks Save Money and Improve Containment

By contrast, SAFE-Tanks help you trim your costs and increase efficiency. Here are several advantages of a SAFE-Tank.

Save Space

Only one tank pad is needed. And because any spills are self-contained, you can store acids and bases right next to each other.

No Coatings

The SAFE-Tank is made of cross-linked polyethylene, eliminating the need for additional coatings or re-coatings. SAFE-Tanks are maintenance-free.

Leak Detection

With the SAFE-Tank, you don’t have to worry about leak detector false positives, because rainwater can’t enter the interstitial space. If the primary tank leaks the operator can use up the chemical and decide when they want to repair the tank.

Reuse the Chemical

SAFE-Tank won’t allow any debris or dirt to get into a spilled chemical. You can easily retrieve the spilled chemical and reuse it. If you’re storing expensive chemicals, this could save a lot of money.

Save Time

Maintenance-free storage means that you’ll save valuable time and hassle, freeing up your staff for more important work.

Altogether, the SAFE-Tank can cost up to 90% less than traditional concrete containment structures. Contact Poly Processing to learn more about how the SAFE-Tank system can help you make containing your chemicals less expensive.
