Rural Roots

A countryside setting places Wieser Concrete Products closer to the customers it serves.

Deep in the Wisconsin countryside, where narrow roads merge with thick woods and rolling hills, the trees radiate with stunning color as another year eases into its final season. Whitetail deer forage in a distant pasture, and the crisp air and crystal streams carry a subtle reminder that city life can never be this peaceful and serene.

You'd never expect a precast concrete plant in the midst of this scenic beauty, yet there it is around the next bend tucked in next to a large tree-studded hill. But it isn't as odd as it may first appear, as this rural setting puts Wieser Concrete Products, Inc., closer to the customers it serves: farmers and other folks who choose to live far from the city limits. It also puts it closer to two aggregate sources the company owns.

Wieser is known throughout Wisconsin and in the surrounding states for manufacturing septic tanks and agricultural products, which comprise the bulk of the company's business. These are the belles of the ball, so to speak, as the company has invested years of experience and slick engineering to bring to market some unique products, most notably a recirculating septic system and a slatted floor system for dairy farmers.

Friends of Nature
A relatively new product emerging from the Wieser plants is the "recirculating vertical flow wetland system," an aeration system that treats septic tank effluent. Many homes in the region currently use a mound system, which reduces or eliminates the need for a holding tank that must be pumped out regularly. The mound systems treat the septic effluent, but homeowners are left with a small hill in their back yards.

"A mound system is a standard septic system," said Andy Wieser, president of Wieser Concrete Products, Inc., and son of Joe Wieser, who established the company in 1965. "But the ground won't accept the hydraulic loading of the effluent, so they mound a pile of sand in your yard and run the pipes through that."

Homes using the mound system typically require 3 feet of treatment zone (the sand) and dirt topped with grass to cover the pipes and sand. "You end up with about a 4-foot-high mound in your yard," said Andy. "And about 50 percent of the septic systems that go into this area are mound systems."

A more effective method of handling a home's sewer is to add a septic system below grade that can take advantage of basic scientific principles and recycle the cleansed effluent back to nature. The DYNO2, an aeration system, takes the effluent from a septic tank, feeds it to plants that eat the pollutants, removes the contaminants and releases clear water into the drain field.

This system, designed by Reactor Dynamics of Forest Lake, Minn., and manufactured by Wieser Concrete Products, is a precast concrete tank that comes complete with all the necessary components preinstalled at the plant. "This unit allows a decrease in the amount of soil needed between the limiting layers, or the groundwater and bedrock," said Dan Jensen, environmental engineer at Wieser's Portage, Wis., plant.

Jensen explained that the effluent from the septic tank enters the DYNO2 through a nitrogen bundle, which provides a carbon source and lades the effluent with ammonia and carbon. Solids settle to the bottom of the first chamber while water passes through a filter and into the second chamber. From that point, the water is pumped into the upper section of the tank, where it travels through a piping system. The water flowing through the pipes draws in air through a venturi and gets saturated with oxygen. The water now contains aerated bacteria that convert the ammonia into nitrates and recycles through the system up to 20 times.

"As the nitrate-laden effluent settles down into the collection tubes, it comes back into our nitrogen bundle," explained Jensen. "Now that the effluent has a nitrated and aerated source, it goes into an anaerobic condition where nitrogen gas is released, thus reducing the total amount of nitrogen in the effluent." The amount of nitrogen removed from the water can be controlled by the number of times it recirculates through the system.

Meanwhile, on top of the system, silica aluminate covers the piping system and provides a growth medium for the bacteria. Sphagnum moss is piled on top, which allows nitrogen and oxygen to be diffused to wetland plants. "Homeowners can choose from 50 different types of wetland plants to put on here," said Jensen. "About the only thing the homeowner has to do is choose which plants or what color scheme they want in their back yards."

As for the water itself, a control panel determines whether the water is clean enough to flow into an absorption field or whether it needs to recirculate. The control panel will alert the homeowner if the water gets too high or too low. In such a case, the homeowner notifies the person in charge of taking care of the unit. It can also be hooked up to a telephone line to perform that task automatically.

Three hatches top off the system. They provide access to the nitrogen bundle, the filter and the pump if maintenance becomes necessary.

Simple hookup is another built-in convenience. "It's your mom and pop plumber who's putting them in," explained Andy. "So when the plumber buys this, after we put it in, all he has to do is hook up the pipes and electricity to it, and it's ready to go," he said.

In larger rural developments, such as hotels, condos and golf courses, the effluent may require pretreatment, and Wieser has an answer for that as well. "We just developed a 40,000-gallon septic tank," said Mark Wieser, P.E., the company's vice president. Mark explained that the newest addition, which has a patent pending, uses post-tensioning technology where each individual section of the tank is post-tensioned.

The DYNO2 system has other uses as well. "We're also using this for milk-house waste for agriculture, when they clean out their milk parlors and wash the animals before milking them," said Jensen. Dairy farmers, in fact, capture a lot of Wieser's attention. Besides manufacturing precast concrete feed bunks, bunker silos and grain storage walls for the agricultural community, the company also builds manure storage systems, including a slatted floor barn system.

Clearing the Air
It's no secret that the country air is fresh and clean, but the nose will usually let you know when a dairy farm is nearby - or more specifically a dairy farm that has no manure storage system. And if the wind is just right and a town is nearby … well, it's just not a good combination.

Manure storage lagoons allow farmers to spread the ultimate product of fertilizer onto crops when the crops need it and when the weather is agreeable. Even those systems require intense labor, machinery and constant maintenance, plus they swallow up precious land. But these are modern times, and there is a better way.

The slatted floor barn system manufactured and installed by Wieser has become a popular commodity in the agricultural community. These manure storage systems are relatively hassle-free because waste falls through the slatted floors into the storage area below, which can be pumped out at a convenient time. And they eliminate offensive odors.

"We developed the first so-called gang slats; all the slats before we started building them were individual slats," said Joe Wieser. "By accident we put our slats together in a panel because they were easier to handle. We made a 4-foot-by-10-foot panel rather than each individual slat." Thus was born a simple and economical solution to building a slatted floor barn system and a better method of handling manure.

The system is built as a precast concrete column-and-beam construction over a concrete floor. Precast concrete walls enclose the storage area below grade and, along with the columns and beams, support the slatted floors and free-stall panels (individual solid-floor stalls where the cows can rest). Access hatches to the storage area are also built into the floor. Once the system is installed, a barn can be built over it.

The company also builds slatted floor systems for calves and hogs, each of which requires a different slat width than mature cows.

Know Your Customer
Providing this level of farming savvy and service requires knowledge and experience. With the plant thriving in the midst of farming country, it's only natural that most of Wieser Concrete's employees come from farms. Some, like Joe, owned their own farms, and most are long-term employees who have become well-versed in the precast concrete industry.

Mike Harmon, for example, grew up on a farm and went to work at the Wieser plant right out of high school in 1969. "I stripped forms for a number of years, ran the mixer for a number of years, worked in the yard for a number of years, and I drove for like 15-20 years," said Harmon. In 1995 he took over as dispatch manager, the position he holds now. "We do have people working for us who have put in years of service. There are guys in the plant with 10, 15, 20, 25 years," he said.

"We have a couple of 30-plus guys still here," said Red Mears, the production manager. "When I got here, 80 percent of the guys who worked for us had grown up on farms. So we understand that (lifestyle)." Mears himself owns a small farm and used to do some farming. Coming on board in 1976, he, like Harmon and others, started at the bottom and worked his way up.

"We have a lot of dedicated employees here that really make us go - each one is very important," said Dan Wieser, who handles the demanding jobs of accountant and corporate secretary. Dan himself has been working for the company full-time since 1982. "But the farming background, yeah, it's very important because they understand what the farmer goes through and what we're trying to do. Probably our best business is the farm business."

Knowledge and experience aside, success has turned on the wheels of plain, hard work. "I like the challenge of getting it done," said Mears. "It's very easy to come to work - because I do like what I do."

Eye on Production
Quality employees provide quality service, but the quality products they make require an additional element: quality control of the manufacturing processes. The premier method of accomplishing that element, the Wiesers have found, is through the plant certification process.

"We've been involved with the NPCA plant certification program for about 14 years," said Andy, who has been on the NPCA Plant Certification Committee for the past four years. "It's been a big benefit to our company."

Andy explained that the inspectors are experienced and usually point out things that had gone unnoticed. They serve as an extra set of eyes and provide useful advice. "Every time we've had an inspection, I think they brought out something that has helped us - from safety points to production tips," he said.

The company has also enjoyed standing out from among its competition because of plant certification, particularly in terms of publicity and recognition from state agencies. Although Wisconsin and Minnesota do not require certification, the Wiesers feel that the state agencies look to the company with added confidence as a result of the certification.

The cost of gaining that certification is perhaps a barrier for some plants, but Andy takes another view. "We're a firm believer that certification saves you way more than the expense," he said. Andy mentioned that some of the little things inspectors pick out add up to a cost savings, but the real bonus is what a company doesn't have to do, such as returning to a job site because a product wasn't manufactured right. "You can't even put a number on it, because if you're doing it right you don't have that cost," he said.

"The certification program has come a long way in the last three or four years," said Andy. He explained that the program is continually being improved, and the quality control manual is much more user friendly and easier to understand. "Any plant can become certified without much help. All they have to do is follow that manual." And now with NPCA's mentoring program, any plant can be matched with a mentor plant to help prepare them for certification.

For a plant by a narrow road in the Wisconsin countryside, Wieser Concrete Products' arms stretch far and wide - the company delivers products not only in Wisconsin and surrounding states, it has reached as far as New York, Pennsylvania, Texas and California. Yet it's little wonder, since the company is known for quality manufacturing and expert service.
