Double Walled Underground Bulk Brine and Salt Tank Storage SystemsWhat is a Bulk Briner?

A bulk briner or salt brine tank system is storage equipment that makes delivering salt to an industrial water softener or manufacturing process safer and less costly.

The Industrial Water Solutions double-walled underground bulk brine and salt tank storage systems are designed to work seamlessly with your industrial water softener system or processing plant to drastically reduce salt costs and remove liability from injury due to loading salt into a brine tank or salt tank storage system. With an industrial softener salt recycling system, a bulk briner can reduce salt to the drain by up to 75%.

As an engineering company, not a salt company, our focus is on designing the best underground briner and salt tank storage systems to integrate with your industrial water softener or process in your new or existing building.

We also offer above-ground bulk brine systems and salt tanks and can consult on which salt brine storage and equipment options work best for your facility. Ideal applications for bulk underground briner storage systems include any facility with high salt consumption or safety-conscious management that doesn’t want to put its team at risk for injury from salt storage loading.

Also, see our single-walled bulk brine storage tank systems that have the same salt-saving potential.

Double Walled Underground Bulk Brine and Salt Tank Storage Systems are ideal for improving safety and cost-savings for:

  • Refineries
  • Manufacturing
  • Food Processing
  • Health Care Facilities
  • Municipal
  • Pharmaceutical
  • Beverage Processing
  • Hospitals
  • Hotels
  • Universities
  • Correctional Facilities
  • Apartment Buildings

Cut Salt and Water Costs while Reducing Your Environmental Footprint with Our Underground Briner and Salt Storage Tanks

Buying and storing salt in bulk will reduce salt and labor costs dramatically. And with minimal design changes to a new or retrofitted industrial softener system, up to 40% of salt costs can be saved while also reducing water consumption. This is not only good for your bottom line, but it’s the right thing to do for the environment.

Double Wall Briner for Environmental Safety

Our double-walled salt briner equipment systems employ a double-walled containment system with leak detection. Suppose there is a breach in the brine system. In that case, it will be contained in the second tank and there will be an alarm to notify staff to investigate, nearly eliminating the high environmental and legal costs of leaking thousands of gallons of salt brine into the soil. We also offer single-walled bulk brine systems for a slightly more economical solution.

Why Underground Bulk Salt and Briner Storage Systems?

Many customers choose underground salt brine makers because they don’t have the space above ground, or they don’t like the aesthetics of above-ground bulk briner systems. The greatest challenge of underground brine storage and generating systems is environmental risk. You can’t see them, and you can’t see if there is a failure. This is one of the reasons our double-walled salt brine storage system is so popular for underground use.

Briner Integration, Engineering, and Innovation

As stated above, we are an engineering company, not a salt company.  We focus on implementing systems seamlessly integrating into your industrial water softener system(s) or processes.  Our goal is to reduce your brine, salt, and water costs while simultaneously reducing your carbon footprint.  We can also integrate with your existing softener or process for an alarm to notify you if your softener or process has a potential failure so you can focus on your core business and not worry if your brine or softener storage system is working correctly.

Automatic Briner Level Controls

Our Underground Briner and Salt Tank Systems include automatic brine level controls, with emergency bypass, so you don’t have to worry about adding water to the underground bulk salt system.

Easy Clean Out

All Underground Bulk Brine Systems are fitted with a top-mounted, many.  This port is used for periodic sludge clean-outs.  Every three years is standard but this depends on salt type and quantity of salt used.

Efficient Pure Brine Collection

The bottom of the tank has a large distribution system that collects brine evenly across the entire tank using a slotted heavy-duty PVC piping system. It filters particles, salt crystals, and other insoluble materials from the saturated brine. If fine-grade salt or granulated salt is used, quartz rock covers the distribution system to ensure only brine enters the distribution system leaving the sediment and salt crystals behind.

Submersible brine pumps can be used in lieu of the brine distributor if external bine pumps are not available or desirable.

Down Flow Brine Making

Down flow brining ensures consistent, high-quality brine saturation. As freshwater rises, the higher-density salt water sinks. Dirt and sludge from the salt are captured at the bottom of the tank and need to be removed periodically.

Dust Free Fast Salt Loading

Salt is loaded pneumatically and has an air vent and bag collection system that produces minimum dust emissions. The connection is a 4″ 304 stainless steel pipe, which is fitted with an aluminum camlock coupling and cap that adapts to a P/D salt truck hose connection. Further salt dust suppression can be added by injecting water during salt unloading, resulting in further minimization of dust emission.


Our tough, double-walled, fiberglass-reinforced plastic shells are constructed to maximize the life of the system.

Uniform Distribution

In many underground briners, inlet water is not distributed evenly. Results are often the formation of salt pillars in the tank These can break and damage the system. We eliminate this with a header the length of the tank.
