KUB Improves Sewer Structure

By  | 

After a big rainfall, you may notice some overflowed sewers.
But two years into their ten year waste water project, KUB says you shouldn't see nearly as many.
Volunteer TV's Kim Bedford has more on KUB's improvements to their sewer infrastructure.
It's been about a year since KUB tacked on a 50 percent waste water rate increase for all of its customers, and they have spent about 84 million dollars on infrastructure improvements so far.
So where has all that money gone and is it really making a difference?
Wayne Loveday with KUB Plant Operations says, "replace or rehabilitate the waste water collection system piping, to build some storage tanks in the system and make some pump station upgrade."
That's KUB's improvement plan over the next eight years, and they say they've cleaned up a lot in just the past two years.
Loveday says, "we had a number of what we called hot spots, where we had reoccurring overflows, several of those have been eliminated."
KUB says one of its biggest sewer overflow spots used to be at Fountain City Lake, but they say the water is under control now.
Renee Hoyas with the TN Clean Water Network says, "kub has done a fabulous job of cleaning up the system."
Hoyas says KUB's sewer systems have come a long way.
"It was really, really bad and we've seen a tremendous decrease in wet water overflows since this program started."
And KUB says they have several new projects in the works.
Loveday continues, "where we go into a neighborhood, assess what condition the pipes are in, then we come back with a plan, either to replace those pipes if they're structurally unsound, or if they can be rehabilitated."
And replacing those pipes costs KUB a pretty penny.
Loveday says, "you couldn't do it without the rate increase. The funding has to be there. This is expensive work. It costs a lot of money to go in and replace old sewer lines, sometimes 20-30 feet deep in the ground."
Hoyas says, "but if you don't fix them, you've got untreated sewage in your neighborhood, flowing down your street."
KUB says the entire ten year project is expected to cost 530 million dollars, which is why all of it customers can expect another 50 percent waste water rate increase in January.
