The city of Richmond heard some good news late last week: Missouri DNR approved its facility plan for a new south waste water treatment plant. Mike Milius, vice president of Olsson Associates and engineer on the project, said DNR approved all options presented for the $10.8-million sewer plant project. Final plans will be sent to DNR by Oct. 12, city administrator Ron Brohammer said. The plan consolidates sewer operations by expanding the south plant, which is near capacity, and closing the north plant.
City leaders were forced to find cost savings on the project due to a new DNR mandate requiring treated waste water to be disinfected – removing bacteria – before being discharged into any body of water. The city’s original cost estimate was completed before DNR issued its new mandate. Previously, disinfection was only stipulated for “full body contact streams.” That change added another $601,000 to the project’s design plan.
“The rule for many years, a full body contact stream, like Crooked River, required UV (Ultra Violet light disinfection) because people may boat or swim in it. A year ago, discharge going into any stream has to have some sort of disinfection – chemical or UV. We found UV as the most cost-effective and effective means,” Brohammer said.
cover it,” Brohammer told the council. “It’s a small amount of money for the potential risk and doesn’t significantly impact the budget.”
