Maybe you are applying for state revolving fund loans and need to illustrate elements of an asset management plan are in place. Perhaps you need to plan for looming asset failures, but you’re not sure what to do, when they’ll fail, or how to pay for dealing with the problem. Using a simple asset management framework, utilities can gain a better understanding of what assets they own, their condition, and the risks those assets pose. The utility can then focus its efforts in the right places, maximizing its resources to reliably provide service to customers. Join B&N’s Kevin Campanella to learn how to develop practical asset management plans for your utility.

The Madison Wastewater Treatment Plant handles the majority of sanitary flows in the eastern portion of Lake County, Ohio. Built in 1974, the vintage plant was at its hydraulic capacity and in desperate need of improvements when an upgrade and expansion was recommended in 2007.

The $17 million project switched plant operations from a conventional contact stabilization activated sludge process to a Biological Nutrient Removal Process (BNR). The project team reused existing structures while planning for future needs and regulatory changes, which was a key part of the project’s success.

Treatment capacity of the plant was expanded from 3 to 5 million gallons per day (MGD) and includes four trains of two-stage anaerobic-aerobic zones for an AO or Phoredox process. The upgrade also allowed the plant to double its peak hydraulic flow from 7.5 to 15 MGD. Additional modifications to the process equipment resulted in a more cost-effective waste activated sludge thickening process, improved process aeration efficiency and control, and high efficiency mechanical mixing of the anaerobic treatment tanks associated with the BNR Process.                

Presenters Bob Schreiner, PE from Burgess & Niple and Dennis Meek, PE from DM Engineering, will discuss the project challenges and solutions implemented during the design and construction of this facility.
