For many living within the city limits, the thought of what happens to the contents of their potty ends when they flush their toilet; but that is just the beginning of a long and complicated journey to a city of Yuma wastewater treatment plant. (more…)
JWC’s Toughest Monster Yet!
Wednesday, March 3rd, 2010The latest version of JWC Environmental’s Channel Monster has arrived. The Channel Monster XD 3.0 has advanced into an ideal 
grinder and screening system for wastewater pump stations. JWC offers a variety of Channel Monster sizes, including 2.0, 2.5, and now the NEW XD 3.0. This is one big Monster!
The XD 3.0 is the world’s largest, most powerful sewage grinder at 13′ (4m) tall, weighing 9300 lbs (4220 kg) and producing 7 tons of cutting force at peak loads. The Channel Monster combines rotating screening drums and a Muffin Monster® grinder to shred solids while processing up to 59 million gallons per day (9306 m3/h). This combination is ideal for pump stations since the grinder shreds rags, plastics, wood, and trash so particles flow easily through pumps and pipelines.
The new Channel Monster XD 3.0 has multiple motors – a 15 hp (11 kW) grinder and 1 hp (0.75 kW) for the drums. The grinder has larger 3″ (76mm) hex drive shafts and stainless steel coil drums with 1/2″ (12mm) diameter rod. This new design features larger cutters, shafts and housings so the grinder can process heavy debris and first flush storm loading.
“We designed thicker cutters for a longer service life,” said Rob Sabol, JWC’s Director of Engineering. “Bigger cutters also help the process – solids are ground up so they pass through pumps but are still large enough for headworks screens to capture and remove them.”
The Channel Monster is offered with several options such as perforated or coil screening drums; JWC’s exclusive immersible motors; overflow bar screens; custom wet well frames and high tech controllers.
“Pumping station designers can now replace bar screens with the Channel Monster so operators never have to deal with solids removal and disposal – eliminating vector and odor problems in the neighborhood,” said Sabol.
Monsters Set the Gold Standard at the Olympics

Whistler gets a dryer, cleaner separation of what goes to the landfill with the Monster Separations Systems.
Whistler Resort, located in British Columbia, Canada is the host for the 2010 Winter Olympics and Paralympics. While athletes around the world have been training, long-planned upgrades to the Whistler Resort wastewater treatment plant had been underway to ensure completion in time for the Olympics where Whistler expects thousands of athletes, spectators, and media. Whistler will also be housing over 6,000 athletes, coaches, trainers, officials and media at their new Athletes Village which, post games, will be turned into a neighborhood, providing 250 residences, recreational facilities and retail services. Whistler knew it had to go for the gold standard when it came time to replace their outdated wastewater system. (more…)
A Deluge of Sewage
Wednesday, November 25th, 2009
Many sewer systems are still frequently overwhelmed. Stock photo source.
In part five of their ongoing series ”Toxic Waters – A series about the worsening pollution in American waters and regulators’ response” the NY Times looked at New York City’s wastewater collection and treatment system and found it’s frequently overwhelmed when it rains – leading to combined sewer overflows (CSO).
The article, titled Sewers Fill, Waste Poisons Waterways, sums up the dire situation: ”Despite (billions in) upgrades, many sewer systems are still frequently overwhelmed, according to a New York Times analysis of environmental data. As a result, sewage is spilling into waterways.”
The article looks closely at the Owls Head WPCP in Brooklyn and the obstacles operators face in treating storm flows…
“The public has no clue how important these sewage plants are,” said Bob Connaughton, the Plant Engineer. “Waterborne disease was the scourge of mankind for centuries. These plants stopped that. We’re doing everything we can to clean as much sewage as possible, but sometimes, that isn’t enough.”
In a related article, EPA Administrator Lisa P. Jackson, said the agency was stepping up its efforts on Clean Water Act enforcement, as WaterTech Online® reported here. There’s also the PBS-Frontline special Poisoned Waters about stormwater pollution and the AP’s on-going series about prescription drugs flushed down the drain (a huge no-no of course!) and their impact on ecosystems. The Atlantic magazine hosted a water conference last month in DC about dwindling supplies of clean water. And so on…
Perhaps the years of public outreach by CWEA, WEF, WIN, NACWA and WWEMA (Water and Wastewater Equipment Manufacturers Association) are finally paying off with more public coverage of America’s crumbling water/wastewater infrastructure.
JWC Lands Major Order for Johnsonburg WWTP Upgrades
Monday, August 17th, 2009
The Grit Monster vortex removal system is both compact and reliable, removing sand, gravel, shells and coffee grounds as wastewater passes through the headworks.
JWC has received an order for several Monster systems to be installed in the Johnsonburg wastewater treatment plant in Eastern Pennsylvania. The order includes several Channel Monsters, Grit Monsters, Screenings Washer Monsters andBandscreen Monsters. The facility is undergoing an extensive upgrade. Mike Perone/DAS is the contractor and Uni-Tech is the Consulting Engineer.
Removing grit at the headworks benefits downstream systems and increases the service life of pumps and process equipment. JWC’s Grit Monster, when integrated with JWC’s Bandscreen Monster become the Monster Separation System: A Complete Headworks – increasing operating life of downstream pumps and systems.
