Message from SIGMA President Larry Rybacki: Waterworks Industry Unites to Fight Childhood Cancer

As The Rybacki Memorial Invitational celebrates its 25th anniversary this September supporting kids with cancer (through The Jimmy Fund at Dana Farber Cancer Institute in Boston), I can’t help but reflect on how grateful I am for the support the Waterworks Industry has given us over the years.

Companies such as: ADS, C&B Piping, Clow Canada, Core & Main, EJ Prescott, EMCO Corp, Ferguson Waterworks, HD Fowler, Hayes Pipe, IPEX, Mid American, Mueller, National Pipe, Putnam Pipe, Romac Industries, Specification Rubber, US Pipe, Warwick WinWater, Western Waterworks, and many individuals who are part of our industry that donate without fanfare.

When you see a child who has been afflicted with cancer and who has beaten this dreaded disease, and realize that in some small way you have had a part in their success it’s heart warming to say the least. We are so proud to be a part of a group of people who don’t hesitate to give back.

My family and I will be forever grateful.

SIGMA is implementing an increase on its line of Municipal & Construction Castings (MCC)

June 13, 2018

Dear US SIGMA Customer:

As previously announced, SIGMA is implementing an increase on its line of Municipal & Construction Castings (MCC).

Over the past few months, raw materials, particularly pig iron, have appreciably increased in Asia. In India, suppliers have absorbed 4 meaningful increases since January. Even today, pig iron and other raw materials remain volatile with almost daily fluctuations.

To address these increases, SIGMA is announcing a List Price applicable to light castings that are sold across regions and even nationwide. These castings include valve boxes, valve box components, risers, cleanouts and the like. This List Price will be published on SIGMA’s website,, by Friday, June 15th.

Your local SIGMA Territory Sales Manager will supply you with the appropriate multiplier.

This new List & Discount will be effective Monday, June 25th.

While we are considering a List & Discount for “heavy” castings to provide more consistency to the pricing policy, Sanitary and Storm Castings typically used on a regional or even local level will continue to be offered with net pricing for the immediate future. Your local SIGMA Territory Sales Manager will supply you with the new net prices for these items.

We hope that you, the customer, will find this new List Price and convenient and manageable means to price these castings.

As always, we greatly appreciate your business and support.

Greg Fox | Vice President of Sales


SIGMA Corporation proudly introduces our SIGMAFlange™ Universal Model SFUP. The innovative design allows for the ease of field flanging plain-end pipe to any flanged fitting, valve or other flanged appurtenance. It incorporates a ductile iron adapter ring, complete with its own O-ring gasket, and a standard or transition mechanical joint gasket while accommodating necessary pipe-end restraint using a SIGMA ONE-LOK™ Model SLGU wedge-action gland. This multi-purpose wedge-style restrainer is recommended for use with the following pipes: ductile iron, steel, AWWA C900 PVC, D2241 “IPS” PVC, HDPE and AWWA C909 PVC. This new product expands our extensive restrained joint product line as part of our ongoing effort to meet the needs of our valued customers.

The SIGMAFlange™ Universal comes conveniently packaged with all necessary components, including hardware, to facilitate handling and installations in the field. Model SFUP accommodates pipe misalignment, is easily disassembled for service and maintenance requirements, and provides a minimum 2:1 factor of safety, based on the rated pressure of the pipe upon which it is installed.

Steve McDonald, Restrained Joint Product Manager comments, “The development of the SIGMAFlange™ Universal exemplifies SIGMA’s ongoing commitment to our business partners, assuring them we have the ideal restraint product for all of their needs. The field flanging of metallic pipes began over 40 years ago with the original set screw adapter flange. The SIGMAFlange™ Universal uses advanced technology and now offers water municipalities and consulting engineers the option of using either metallic (ductile iron and steel) or non-metallic pipes (PVC & HDPE) in flanged applications. It also provides a robust restraining mechanism for various types of pipes.”

The SIGMAFlange™ Universal is electro-deposition coated with a top coat black enamel and currently available in sizes 3″ through 12″ with 14″ through 36″ coming soon.

SIGMA Introduces New Hydrotec Products

As an industry leader and innovator in drainage solutions, SIGMA has introduced several new Hydrotec product lines this year. These include:

Hydroline Pro: This aluminum version of the Hydroline Ductile Iron Trench Drain System offers several key advantages. Aluminum is a lighter weight material, so this system is fast and easy to install. Hydroline Pro is offered in 3 meter and 1 meter sections in nominal 4 inch internal width channels. The single piece design is flexible and scalable; channels can be hooked together with flanges to create 8, 12, or 16-inch wide channels. Hydroline Pro is ADA compatible with a load class F rating, and the aluminum material resists rust and bio-growth. This new system is ideal for low flow areas in applications such as swimming pools, driveways, gardens, bay doors in loading docks, and some food and beverage applications. Hydroline Pro comes standard in Jet Black (powder coated) or raw Silver. Other colors are available with minimum order quantities and a slight up-charge.

Maxi Pro: This fiber reinforced concrete channel offers an innovative new feature. It now has a neoprene insert, which serves two important functions. First, the neoprene alleviates the clanking sound resulting from vehicles driving over the channel. Secondly, it cushions the grate, absorbing vehicular loads, thus significantly reducing friction and wear and tear. This increases the durability of the components and extends the life of the system.

HydroBlock: These single piece, monolithic ductile iron trench drains are now being manufactured with ADA compliant features. HydroBlock tops in 6, 8, and 12-inch systems now meet ADA requirements. HydroBlock is ideal for Airport, Port/Dock, Intermodal, and Distribution Center type applications.

SIGMA continues to grow in the trench drain sector; the expansion of our offering with these three new lines enables us to meet any and all drainage requirements and specifications. Our team is standing by to answer your questions and respond to your request for quotes. For information about these and other trench drain solutions, please contact National Trench Drain Solutions Product Manager Todd Amerson at

August 2, 2017

From : Siddharth Bhattacharji & Victor Pais

On behalf of Siddharth and myself, I am glad and grateful to announce that, through an investment
group we put together including Larry Rybacki, our longtime friend and partner, Mitchell Rona and Jeff Marcus, key senior SIGMA executives, a few other management members, a couple of long time business friends and most importantly, certain affiliates of Fairfax Financial Holdings Limited (Fairfax) of Toronto, Canada, we have acquired the entire stock of SIGMA International Group, the parent company of SIGMA Corporation and related companies as of August 2, 2017.

Interestingly, it was almost ten years back that Frontenac Company of Chicago, IL had acquired
majority shareholding of SIGMA from the original shareholders that included us and several of the
key executives who are now new investors.

Over the challenging years under their ownership, including the severe financial crisis and the
ensuing market downturn, Frontenac provided sound support and guidance in any and all ways. And
after almost ten years, they decided to initiate a succession in keeping with their investment

As we both had continued to be close to SIGMA, we identified it as an opportunity – as a sound
investment, but also to head off uncertainty any new ownership change entails and instead, to make
a ‘fresh start’ to revive the dynamic, entrepreneurial and growth driven team ethos that marked our

Armed with a pragmatic ‘blueprint’ for long term growth, we approached Fairfax, a stellar
investment company, with proven commitment to sound and steady long term growth and healthy return on investments. Founded and led by a widely respected and internationally known visionary leader, Prem Watsa, Fairfax has grown from strength to strength over its 32 years since inception, as a value investor leveraging their vast resources from their growing core insurance business. Prem has guided Fairfax from its modest start in Canada to its current robust global stature, on the
strength of a set of ‘guiding principles’ he set out from the start and consistently followed —
such as sound financial management, long term value creation, decentralized management culture,
spirit of sharing and equally, having fun – at work! Incidentally, these were the very same values
we built SIGMA on,too…

I have been blessed to have enjoyed a close and trusting friendship with Prem that has thrived for
over 50 years, going all the way back to our years together at IIT-Chennai, a top engineering
institution, then and now. With experienced founders and a strong, reputed financial partner like
Fairfax, Frontenac welcomed our proposal favorably and in a relatively short time, we concluded a
transaction all stakeholders feel positive about.

Siddharth and I are humbled and honored, yet excited too – to have an opportunity to lead SIGMA
again, which has a loyal, experienced and market savvy team. Together again, we will strive to
build on the well- recognized SIGMA customer service, with new products, services and systems,
responding to the ‘voice of the customer’, to be a growing ‘value supplier’, while also bringing in
some newly developed synergies, from our other businesses in Waterworks and related industries.

Jim McGivern, the CEO for the last 8 years will also continue his association with SIGMA, albeit in
a non- executive but formal advisory capacity. He will assist SIGMA to identify and nurture any
strategic growth opportunities.

While Fairfax will be a great partner, to mentor and guide us with their proven financial and
governance acumen, their established philosophy is to extend complete autonomy to the new SIGMA team.

SIGMA going strong after 32 years…Siddharth and I celebrating our 40 years as partners and 27 years with Larry…Prem and I sharing a close friendship for 50 years…Durability and Long term are
certainly in our DNA!

We look forward to an enjoyable and rewarding journey…that we call SIGMA 3 .0 ……
