A new pump series from Gorman-Rupp
September 28, 2015

Gorman-Rupp is introducing the new 6500 Series of end-suction pumps for a variety of in-plant applications in both potable and wastewater systems. The product is on display at WEFTEC 2015.

Council Bluffs may have fared even worse than Omaha in recent storm
September 26, 2015

It's thought that parts of Council Bluffs got more than 6" of rain in 24 hours in the recent storm. Most sewer systems would be challenged by that high a rate of flow in part because it's really well beyond what historical models usually told people to design around.

Omaha just had its 4th-rainiest day ever
September 25, 2015

5.74" of rain fell in one day -- enough for a top 5 ranking since records have been kept. It's a testament to the need for good stormwater management systems.

What you should know about corrosion in drinking water systems
September , 2015

The CDC has some helpful information on corrosion in potable water systems and how it is caused. Useful knowledge for those in municipal water systems.

Cedar Rapids may demand more topsoil
September 16, 2015

As a stormwater management issue, Cedar Rapids may soon require that 8" of material be left behind after new construction to help absorb stormwater from heavy rainfall. That would be more than the usual 4" topsoil requirement, but it's easy to understand why Cedar Rapids may look to implement a tougher standard, given the city's experiences with flooding.

"Waters of the United States" is coming
May 26, 2015

The EPA is likely to issue "Waters of the United States" regulations in the next few days, according to The Hill. The draft proposal attracted a lot of attention from supporters and opponents alike, and the new rules ought to be even more attention-grabbing as they will represent the actual law to be enforced.

New fluoride standards apply
May 18, 2015

The U.S. Department of Health and Human Services has revised the recommendations for optimal fluoride levels in public water supplies, closing the range from 0.7 to 1.2 ppm to now simply the lower bound of that range, 0.7 ppm. The agency says Americans are exposed to fluoride in enough other places that they don't need to get the full allotment from public drinking water. Fluoridation of public water supplies has been a resounding success for public health in the United States, and it is good to see that the recommendations are adapting in the presence of new evidence and changed circumstances.

We can help you with water-quality monitors for fluoride. Please feel free to contact us with your questions.

A record-dry March for central Nebraska
April 30, 2015

There hasn't been a drier March in central Nebraska in 121 years of recordkeeping. Coincidentally, we gave a presentation on weather extremes and their effects on water utilities in the middle of March in the middle of Nebraska (at a conference in Kearney), obviously not knowing how the month would turn out.

Preserving institutional memory in a utility
April 27, 2015

Retirements, illnesses, new jobs, and plenty of other factors cause institutional memory to leak out of a utility. Join us at the Iowa AWWA short course in Ankeny today for a presentation on how to patch those leaks. One selection from our extensive library of presentations for the water industry.

"The rise of luxury toilet paper"
March 26, 2015

That's a real headline on an article from the Washington Post, which documents that Americans spent $1.4 billion on "luxury" toilet tissue. Here's a thought: Perhaps we should apply a "luxury tax" to "luxury" toilet paper and use it to subsidize improvements to our water and wastewater infrastructure. A 10% surcharge on $1.4 billion would be a modest down payment towards the $298 billion that needs to be spent maintaining our wastewater infrastructure and modernizing it for the 21st Century.
