Cleaning with Creativity and ITpipes

Simple innovation makes easy work of a difficult cleaning job

No vehicles, no heavy equipment, yet the job was cleaning 10,000 feet of 27- to 30-inch sewer main.

The site was the Four Seasons Golf Course in Irving, Texas, and the job would take thousands of feet of hose using conventional methods like a combo unit.

“You’re not bringing anything on the golf course that is much larger than a golf cart,” says Rusty Nezat, owner of Nezat Training and Consulting. “You couldn’t bring any jetters — none of that equipment could be brought out. No pickup trucks — nothing like that could be brought out on the course.”

The project consisted of two separate lines, a clay tile main and an HDPE bypass, both about 5,000 feet. Mineral deposits up to 8 inches were accumulating sediment, restricting flow.

Nezat’s solution was a patented, proprietary piece of equipment called the Jigawon. It is a large-diameter cleaning device that uses existing flow in the pipe to create head pressure and migrate silt and debris downstream. Controlled by a trailer-mounted cable winch, in turn pulled by a small tractor, the device is essentially an inflatable canvas-type holding container with a conical extension ending in a plate on the front, where a series of jets channel about 3,000 gpm at 15 psi.

“It’s a canvas-type material that catches the water and restricts it, and it pushes against the edge of the pipe, so you get a scouring action on the pipe while it’s capturing the water,” he says. “It’s a combination of a kite, a scraper and a sewer ball, which is all old technology. I kind of combined the best of all three and made a new device. It worked really well, and that’s how it was born.”

Soft and slow

“It’s very slow because the process is very slow,” Nezat says “It’s a very soft process, so to speak.”

Despite its slow speed, the process is cheap and noninvasive. Nezat’s bid beat out the competition by about $2 million, and because the system uses existing flow, it doesn’t even need a bypass. With this process, Nezat can clean up to 6,000 feet at a time, allowing him to do the 10,000 feet of this job in only two runs, all without putting a single tire mark on the fairways.

A post-cleaning inspection video and condition assessment coded with ITpipes inspection software accompanied the Jigawon process, proof of concept for the device and proof of a job well-done.

According to the director of the golf course, “the project was successful on every level.”  Read the full article here.
