JWC Environmental’s latest generation of washer compactors, the Monster Wash Press, has arrived and is ready to grind, wash and compact your toughest screenings. It features a new Muffin Monster® with the power of a 40K in a 30K package!
The grinder effectively shreds rags, plastics and trash to promote removal of soft organics and fecal matter from the screened debris during washing. The newly added paddle rotor agitates shredded material to improve diffusion of spray wash water throughout the shredded screenings for even better rinsing of the soft organics out the screened solids.
The new Monster Wash Press has now reset the standard for the best washer-compactor technology in the wastewater industry.
Segmented auger rotor brush for easy brush replacement
Removable top cover and drive end plate minimizes clearance space needed to remove rotor and screen
Field replaceable screen
Multiple inspection ports for easy examination of equipment and operation

How much does the trash people are flushing down the toilet cost local sewer agencies? Few people know the answer and few records have been kept in the wastewater industry. Until now. Starting in 2013 many of the wastewater associations have started gathering detailed research on the cost of pumps clogged with flushable wipes – equipment damage, labor costs, overtime, sewer spills, wasted electricity and the expense of retrofitting pumps with better impellers or installing a sewer grinder, such as the Muffin Monster.
What the data gathering efforts are finding is sewer pump ragging is costing the industry hundreds of millions of dollars in wasted effort and needless repair every year. The research has found the average cost of clogged sewer pumps is $30,000 per year, per pump station. These pump stations average about 1-10 million gallons per day (150-1500 m3/h) of raw sewage.
Here are some recent studies…
Orange County, CA – $30,000 per year/station – Analyzing 10 pump stations for 1 year this agency found they had over $300,000 in additional labor and parts for deragging pumps. At some stations, they are deragging pumps on a weekly basis.
New England – $29,000 per year/city – According to a survey conducted by a regional wastewater association
Southwest Washington State – $32,000 per year/station – This agency added wasted electrical usage to their cost calculations, while also looking at wasted parts and labor costs. As rags build up on the pump’s impeller it causes drag and pumping inefficiency. Variable frequency drives will speed up to move the same amount of wastewater, thus wasting electricity. As the build-up of rags worsens an additional pump may be needed to make up for the pump that is becoming clogged.
Chicago Suburbs, IL – $19,000 per year/station – When this town’s main lift station would rag up, the sewer agency hired a vacuum truck company to go and clean out the lift station and get it working again. This occurred on a weekly basis.
There is a cost even more important to consider when looking at the problem of pump ragging – the safety of America’s wastewater professionals. Deragging a pump by hand is not only labor-intensive, messy and costly – it’s also dangerous. No one should have to derag a pump.
When called upon to derag a sewer pump wastewater professionals are exposed to:
Confined space danger
Hydrogen sulfide gas
Hypodermic needles flushed down toilets
Diseases and viruses
In the last 5 years alone, JWC Environmental has installed over 4,000 pump station grinders. If each station was costing a local sewage agency roughly $30,000 to deal with, then with the Muffin Monster grinder, which makes pump ragging go away, it’s saving America’s sewer agencies roughly $120,000,000 per year. That’s $120 million every year. But more importantly, at least in our opinion, we’re saving America’s wastewater professionals from the dangerous task of deragging sewer pumps by hand.

We here at JWCE have learned a few tips and tricks after installing over 35,000 Muffin Monster sewage grinders to deal with pump ragging problems. As we travel across the nation solving ragging problems we see some of the same challenges in every city.

Well known for innovative water recycling programs, the Irvine Ranch Water District is building a new biosolids and energy recovery facility at their Michelson Water Recycling Plant in Irvine, California. Design engineers have specified Muffin Monster sludge grinders for several demanding solids reduction applications, including grinders for a new grease receiving station. The biosolids processing facility is being constructed to accept liquid restaurant grease, pump it into the digestion system and turn the grease into biogas and then into clean electricity.
In May, the project contractor – a joint venture of Filanc and Balfour-Beatty – placed an order for 17 in-line Muffin Monster sludge grinders for the new Biosolids and Energy Recovery Facility.
“Irvine Ranch Water District is known for innovative water management, so we’re proud to be part of this project – it represents the cutting edge in recovering resources from sewage,” said Scott Kelly, VP of Sales and Marketing for JWCE. “Reusing restaurant grease to produce energy is a win-win for the environment and for local residents, which includes several JWCE employees.”
The jacaranda trees are in bloom in Riverside and, according to Robert Filiar, a forester for Riverside’s Public Works Department, account for at least 4,000 of the 115,000 street trees. They bloom in the spring, with several thousand beautiful tiny purple flowers. These tiny flowers last for two or three days, then fall to the ground, in gutters, ponds and swimming pools, creating thick carpets of lavender and havoc for the city
So what’s this got to do with Muffin Monsters? According to its maintenance operators, there are ten jacaranda trees that bloom near the eight duck ponds on the grounds of the Jerry L. Pettis Memorial VA Medical Center in Loma Linda. These ponds also double as a source of irrigation water for the VA’s grounds. Crewman work full-time skimming the ponds to keep these flowers from floating from pond to pond and clogging the water filters.
What flowers escape the skimmer are chewed up by a Muffin Monster in an underground bunker, the VA’s last line of defense to keep jacaranda flowers from clogging its water filter.
