One man with an energy saving vision

The story of Derceto and Aquadapt began with one man and his vision of how New Zealand’s capital city – Wellington – could achieve major energy savings in its water reticulation by applying sophisticated modeling techniques developed for New Zealand’s national hydroelectricity generation system.

Back in the late 1990s, Murray Kennedy, then a senior manager for Wellington’s Regional Council (now known as Greater Wellington Regional Council), drew on his experience gained in the electricity industry when low water levels in the country’s hydro lakes precipitated a national power crisis. In response, an existing modeling system was further developed so storage of hydro water could be more effectively and efficiently managed and accurate forecasts could be made to ensure supply could meet demand.

“Applying these learnings to the water industry I could see that our current practice of using expensive peak electricity during the day to keep reservoirs topped up was not cost-efficient. There had to be a better way,” Murray Kennedy recalls.

Q: Isn't this software going to have a big impact on my control network?

A: No, Aquadapt software collects data from the SCADA server once every 10 minutes. It reads just storage tank levels and flow totals. Typically this takes milliseconds and will be unnoticeable to the operators. Note it gets this data from the server and not from the field so there is no impact on your telemetry operations at all.
