They might be convenient, and they might make housekeeping less of a chore, but those “flushable” white squares have created a giant headache for municipalities. The cost of removing wipes (nonwovens) from household plumbing, collections systems, lift stations and treatment plants has reached millions of dollars for some cities.

New York City estimates costs of $18 million over five years related to wipes; Orange County, California, reports spending more than $300,000 in one year. Several Minnesota cities have filed a lawsuit against the wipes manufacturers.

Still, the costs keep rising. Public education might be the long-term solution, but until then, municipalities must address the issue with equipment upgrades. At the 2016 Water & Wastewater Equipment, Treatment & Transport (WWETT) Show, manufacturers including Gorman-Rupp Company displayed products aimed at wipes.

“People keep flushing wipes, so you have to change your equipment,” says Mark Schneider, district manager, as he discussed the company’s Eradicator. Built to create an obstruction-free flow path, the Eradicator is a solids management system available on new Super T Series pumps or as a retrofit to those pumps.

“New sewage includes the disposable wipes that aren’t disposable, and even adult diapers or any diapers,” Schneider says. Whether it’s hair, plastic gloves, plastic bags, stringy material or wipes, the Eradicator passes material through the pump without interrupting service. A self-cleaning wearplate and a series of notches and grooves on its lacerating teeth grind the solids so that they pass straight through, staying clear of the eye of the impeller. The product includes a lightweight inspection cover for easy access to the impeller; it is necessary to remove the entire back cover assembly to gain access.

The device is available in Gorman-Rupp Hard Iron or cast iron. Besides municipal applications, it has been installed in clog-prone industrial sites such as poultry-processing plants where feathers can wreak havoc on pumps. Schneider says the smooth-bore design is all about preventing snags and thus lowering life cycle cost.

Innovations like the Eradicator kept the Gorman-Rupp WWETT Show booth busy. Although they saw the most foot traffic on the first two days, the company’s booth, filled with shiny new pumps in signature cobalt blue, stayed busy throughout the show. The company has noticed an uptick in international attendees.

“We’ve had lots of international folks coming through,” says Schneider. “We also have a Spanish-speaking person on staff, which helps.” 419/755-1011; www.grpumps.com.
