Problem: Due to a need for increased capacity, a Midwestern municipality was in the planning stages of replacing a 52-year-old, 568-foot, 36-inch trunk line that fed the city wastewater treatment plant. The city had been unable to clean this pipe with traditional methods due to heavy contamination of debris and grease.
Solution: The Kaiser Premier AquaStar was utilized on this line to demonstrate the recycler’s productivity to run without running out of cleaning water. The AquaStar worked the line nonstop for 5 hours utilizing a step-clean method every 50 feet, successfully cleaning 450 feet of the pipe. The recycler processed over 22,000 gallons of recycled fluid for cleaning with only a single 700-gallon freshwater fill-up. The end of day offload was approximately 8 yards of decanted, compacted material from the bottom of the pipe. As an unforeseen benefit, every time the floor cleaner nozzle broke into new material there would be a release of hydrogen sulfide gas. This began a revelation by the municipality that the $750,000 spent annually on product for chemical mitigation of hydrogen sulfide could be reduced.
Result: The municipality was able to clean this difficult pipe instead of the costly replacement of the trunk line and reduce the cost and use of chemicals.
