Tonka Water Introduces BLEU Underdrain

Tonka Water is pleased to announce another revolutionary new product, the BLEU™ underdrain. BLEU™ is a Blockless Engineered Underdrain and can be combined with Tonka Water’s Simul-Wash™, plate settlers and other products to offer a complete treatment system with guaranteed results. 

“Our customers needed a new approach for concrete filters, and our engineering team designed and developed a low profile, modular underdrain system with flexibility for different basin sizes and profiles,” said Steve Kari, Vice President of Engineering. “This product combines our new gravel-less underdrain design with proven airwash distribution, and integrates beautifully with our Simul-wash™ backwash system for superior performance and cleaning.”

The BLEU™ underdrain is the lowest profile to other stainless steel or block systems on the market.  BLEU™ laterals are durably manufactured with stainless steel and are designed to sustain pressure surges with no damage to the system.  Even flow distribution with no dead zones between laterals is achieved because the air scour is located outside of the underdrain, on the concrete floor.  Simultaneous air and water create a collapse pulse action throughout the filter which fully and effectively cleans filter media, resulting in longer media life and lower operational costs. 

Prior to our first installation in Vega Baja, Puerto Rico, the BLEU™ underdrain design was independently verified using Computational Fluid Dynamic Modeling (CFD) demonstrating that it performs well within industry mal-distribution tolerances.

Ideal for retrofits or new construction, the BLEU™ underdrain delivers results with low profile, efficient design, installation and operation. Call us today for a proposal on your next project.

Product Highlight: DTS

Among Tonka Water’s broad product offering is the Delivered Treatment System, or DTS™, an innovative way to incorporate different kinds of equipment into a complete building. 
Two recently commissioned projects illustrate how different treatment plants can be architecturally unique, but incorporate the same treatment processes. One project ended up with a traditional brick and mortar plant while the other chose the more versatile DTS™ option. Tipping the scale in favor of the DTS™ was the small footprint and easy integration with other on-site elements.  Both projects had similar flow rates and treated for iron and manganese.

Both projects had low flow rates (around 100gpm) utilizing vertical pressure filters incorporating the Simul-wash™ backwash system to treat for iron and manganese. Although the projects used the same equipment and had similar treatment needs, the DTS™ project proved to be almost 1/5th less in total cost. Choose the cost effective DTS™ for your next project – you’ll be glad you did.

American Iron and Steel Act: Don't Be Surprised!

The American Iron and Steel (AIS) requirement was signed into law in 2014 and Tonka Water has seen firsthand that many engineers, contractors, and communities were surprised by the law and how it affects the cost of their projects when funded by a State Revolving Fund.

The language of the act “requires Clean Water State Revolving Fund (CWSRF) and Drinking Water State Revolving Fund (DWSRF) assistance recipients to use iron and steel products that are produced in the United States.” 


If a project is funded even partially by a revolving fund, the American Iron and Steel act applies. This is a permanent requirement for all CWSRF projects, but applies to DWSRF projects through September 30, 2015 (originally it only affected projects during the 2014 fiscal year, but was extended). The only way to circumvent the requirement is by waiver. These are given by the EPA on an individual project basis, and have been rare.

The American Iron and Steel requirement can affect the cost of a project significantly, especially when it comes to automated valves and flanged piping. Subsequent to the legislation, clarifying memos from the government have required valve bodies, flanged piping and steel tankage to fall under the regulation. Tonka Water’s cost for AIS-compliant valves and piping can increase our equipment costs significantly since there are relatively few manufacturers that still domestically cast and machine these products. Many times, to comply with AIS, manufacturers make special provisions that increase costs and stretch delivery - sometimes doubling delivery times! 

In addition to cost, the timing of a project can be affected if the AIS requirement is not identified early. Because of the high amount of foreign-produced stainless steel on the market in the U.S., the cost of steel in general has been driven down over the past few years. Some US manufacturers have had to lower rates of production to keep costs down, which means their products not only have higher prices, but also the US products are now more scarce - and more expensive. 

All of these dynamics can stick engineers and communities in an awkward position, resulting in under-funding of projects, and exceeding construction estimates. It’s important to identify early if the AIS requirement applies to your project so that it can move forward - with no surprises!

Dualator III: Engineered to Succeed

Tonka Water’s diverse product offering provides customers with the peace of mind of comprehensive engineering and execution. A great example is found in the design and application of the Dualator® III. This multi-cell gravity filter incorporates aeration, detention and filtration in one low profile vessel. Dualator® III filters are a great solution for a number of treatment needs including  iron, manganese, arsenic and radium removal, and membrane pre-treatment. This system also has many options for customization including Tonka Water’s unique Simul-Wash™ backwash system that cost effectively cleans filter media and saves up to 50% of backwash water.

Carmel, Indiana

One of many successful installations of the Dualator® III is in Carmel, Indiana. This community, 30 miles north of Indianapolis, designed a new iron removal water treatment plant around Tonka Water’s Dualator® III concept. This proved to be a very economical treatment solution that met the community’s treatment needs as well as streamlined the construction of the project through pre-purchase of the equipment. The Carmel Water Treatment Facility includes three 950-gpm Dualator® III units for a total plant capacity of 4 MGD. Each Dualator® III also includes Simul-Wash™, Tonka Water’s superior backwash system that saves up to 50% of backwash water waste.

Water treatment begins as raw water enters the aerator at the top of the Dualator® III where air is introduced to promote iron oxidation. The oxidation is completed while the water serpentines through the 30-minute detention section. Water is uniformly collected and transferred by gravity to the filter compartment where it is uniformly distributed into each filter cell. It then filters through a dual media consisting of silica sand and anthracite where the iron precipitates are removed and the effluent water flows into the clearwell.

The Dualator® III is a full system solution that meets a broad range of customers in both cold and warm climates. The design has a low profile that easily can be incorporated inside utility buildings, but is tough enough to withstand a more exposed environment outside of a building, in more temperate climates. 

Tonka Water has put significant design engineering into our line of Dualator® products in order to provide consistency in treatment throughout the years, proven again and again with nearly 100 installations. Our years of engineering and design of this product line guarantee our customers that they’ll meet treatment standards set by USEPA, 10 states, as well as Canadian standards, and we have no equals in the breadth of our install list. 

Take advantage of our extensive experience and the leading design of the Dualator® III for your next project!
