Pipe Wars

Pipe Wars
Did you know there's a battle going on under our feet? A recent New York Times article unearths the lobbying war between two powerful industries, plastic and iron, over the estimated $300 billion that local governments will spend on water and sewer pipes over the next decade.

To be sure, pipe material selection can be a complex process. Piping material choices can be influenced by a whole host of factors such as geography, soil characteristics, flow capacity needed, system pressures and more. Some utilities use a single type of piping, while others may use a wide variety depending on specific sites and needs. Moreover, municipal and utility leaders must then navigate through budget constraints and marketing hype as manufacturers fight for a piece of the infrastructure pie.

It is no wonder that operators may need more information before making piping decisions. This webinar video from the Water Research Foundation about the State of the Science of Plastic Pipe provides case studies of how different utilities choose piping materials. The researchers involved in this report found that one of the most important considerations when choosing piping material is overall life cycle cost. 

Don't forget that there may be unique considerations to include in the decision-making process. For example, last month Bruce Macler from USEPA Region 9 wrote to us to let us know that "an interesting outcome of the recent California wildfires was that plastic water & sewer lines melted in some areas."  Who would have thought?

It's Alive! Spooky Sewer Creatures and Things That Go Bump at the Treatment Plant

It's Alive! Spooky Sewer Creatures and Things That Go Bump at the Treatment Plant

Every water system has its stories  whether a particularly forceful water main break or sewage overflow, an unwelcome water tower visitor, or a “worse day ever” inside the treatment plant.

This Halloween season, we thought we would share some of the spookiest water operator videos and news stories we have come across, all with one thing in common: they really happened! (Because we all know that truth is scarier than fiction.)

Let’s start with a quick video and resource about a rare, but certainly not unprecedented, hazard. Hopefully, you will never encounter this slow-moving fleshy blob in your wastewater treatment plant or collection system, but just in case you do, you can thank this blog for warning you!  

No, it isn't an alien from another planet. This nightmare blockage is nothing but a nest of tubifex worms. Along with red worms, blood worms and midge flies, these worms are a normal and occasional nuisance to waterwaster operators, as they can clog filters and eat good bacteria. Although it isn't easy to get rid of them, this website offers hope. 

Speaking of blobs, earlier this year a water utility worker fell off a water main and found himself stuck in a blobby, muddy trench. The more he moved, the more stuck he got. Luckily for him, his nightmare didn't last long  fellow workers quickly came to the rescue, using their knowledge of trenching and excavation safety principles.

One thing is for sure: strange encounters are never far away when you work in the water business. In fact, sometimes spooky creatures are as close as the microscope slides in your lab.

Wastewater plants in particular house microbiological zoos of the strangest kind. But don't worry about what you can't see, because these creepy-crawly microorganisms are really the good guys at treatment plants. The predatory suctoria, for example, uses its spines to suck out the nutrient-rich cytoplasm of organisms it has speared, aiding in breaking down and removing nutrients and organic matter. Or the mysterious Tardigrade (aka water bear) seen below in this video whose appearance usually indicates good BOD degradation. Water bears can survive in outer space, extreme radioactive environments and high temperatures, making them one of the "toughest animals on earth".

In addition to strange creatures, strange happenings can also be part of the day-to-day life of a water operator. This Wessler Engineering blog post entitled "Is Your Wastewater Treatment Plant Haunted? describes an acoustic phenomenon known as "water hammer" that can occur inside the walls of a home as pipe fluids suddenly stop or change direction. This same thing can occur at the treatment plant when automated solenoid valves abruptly open or close, causing a sudden loud boom or knocking. It would be enough to make any night-shift operator jump! 

Finally, we leave you with a story that is sure to give you the shivers. Recent hurricane flooding in Houston has jarred many manhole covers out of place (more than 65, in fact), and somehow a man fell into a pit that feeds underground sewer lines carrying residential wastewater. After over a week underground, the man was finally discovered by utility workers who were nearby making repairs and heard a disembodied voice crying, "I am here, I am here!". After tossing the man snacks from their lunches, rescuers were able to haul the man to the surface. Thankfully this story has a happy ending, but be sure to watch where you are walking this Halloween. 

Raise your profile with AWWA’s Drinking Water Week

Raise your profile with AWWA’s Drinking Water Week

This week marks the American Water Works Association’s drinking water awareness week, and they are offering a suite of free materials for water operators and utilities to raise you profile in your local communities.

“This year’s Drinking Water Week will motivate water consumers to be actively aware of how they personally connect with water,” said AWWA Chief Executive Officer David LaFrance. “We should all know how to find and fix leaks, care for our home’s pipes and support our utility’s investment in water infrastructure.”

The materials – which include artwork, public service announcements, press and social media posts and more – provide an introduction four key steps AWWA is highlighting for water users this year:

  • Drinking Water Week Introduction – AWWA encourages getting to know and love tap water.
  • Get the Lead Out – Replace lead-based water pipes and plumbing.
  • Check and Fix Leaks – Conserve water by checking and fixing leaks inside and outside the home.
  • Caring For Pipes – Stop clogs before they happen by learning more about what can and can’t be flushed.
  • Water Infrastructure Investment – Protect your water supply by advocating for investment in the repair and replacement of infrastructure.

Help celebrate the rest of Drinking Water Week, and bookmark their materials for the next time your program wants to promote these issues.
