Embracing change yields
major savings for WaterOne

A willingness to change traditional thinking and methods of operation has resulted in annual energy cost savings of more than a million dollars a year – around 20 percent of the total annual energy bill – for Kansas water utility WaterOne.

Serving 400,000 people in Johnson County, near Kansas City, WaterOne draws raw water from the Kansas and Missouri Rivers and distributes a peak supply of 200 million gallons a day of treated water via more than 2,500 miles of piping spanning 270 square miles. 

Chuck Weber, WaterOne’s Superintendent of Operations, says that when Derceto approached him with a proposal on how Derceto’s Aquadapt could achieve significant operational efficiencies and deliver energy savings, a lower overall carbon footprint – as well as improving water quality – he was a little skeptical.

“I was taught one of the most important things in operating a water treatment plant is to keep the flow constant. But the Aquadapt solution delivers energy savings and other benefits by occasionally changing the flow. Also, in our industry energy saving has not been given a high priority. We tend to see the energy costs involved in maintaining a constant flow through the system as just a cost of business,” Chuck Weber says.

“But times are changing. Achieving the lowest possible carbon footprint, and delivering water to our customers in the most sustainable way possible is important. The possibility of doing that, while at the same time lowering our overall operating overhead, could not be ignored – even if it required challenging our traditional methods of operation.”

Q: How far ahead does Aquadapt software Schedule?

Dec 04 2010

A: Aquadapt software schedules up to 48 hours ahead but displays a 24-hour window of time on the operator screen. This shows the previous three hours and the next 21 hours. As the day progresses Aquadapt software continues to create new schedules for the rest of the current day and the whole of the next day. At the end of the day there is 24 and a 1/2 hours of schedule, and half an hour later as the day rolls over the Aquadapt software goes back to full 48 hour scheduling.
