We have customized the CCTV portion of Nu-Pipe in the same way we have customized every other portion of the company. We committed to specializing in stormwater. Therefore, we bought robots that are larger, more powerful, and more rugged than those designed to work in sewer or water lines. Our cameras stabilize the picture as they traverse the corrugations in CMP; they crawl over or through debris, sticks, brush, and sections of steep incline; they can turn up to 75º to allow us to continue through buried junction boxes where cross lines may intersect trunk lines, and they are large enough to produce good picture quality from the center of the pipe in pipes up to 84″ in diameter.
As you can see, the road in the picture is very close to the revetment. The soils behind the revetment had begun to erode into the creek, which moves quickly around this bend in the creek. That road happens to be the only road leading to the Ocean Course at Kiawah, which is scheduled to host another major championship, the PGA, in 2021. Kiawah was about to spend upwards of $200,000 to stabilize this bank and revetment to keep that road, and keep the major championship a go for 2021. Again, there is no other way to get to the Ocean Course. We did this project for less than $70,000. As you can see, we pumped through the revetment to fill the void that was there and stabilize it. As we were pumping there, we had material travel through a void all the way to the road travel up through the compromised dirt adjacent to the road. We were able to do all this without causing any disruption to the wildlife in the creek, the wetlands, the road, or any vacationer, golfer, or home owner.
The trick was that we calculated exactly the pressure at which we had to pump to keep get the material to travel where we wanted it, but not enter the creek in its liquid form.
Entering the creek in liquid form would've increased waste and job cost, but also caused an environmental hazard. The material is not stable in its liquid form and is dangerous to wildlife in that form, though in its reacted solid form it is not dangerous and can even be consumed by humans.
That calculation saved a great customer of ours a lot of money and saved a major championship.
