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.

FAQ

Q: We have some large pumps, how many starts per day will be scheduled?

Dec 05 2010

A: Aquadapt software schedules pumps within modifiable criteria. This can include restricting the number of starts per day or even the time slots when starts are permissible; to align to shift changes for example. We can even work out the cost impact of reduced starts so you can evaluate the cost benefit of allowing more starts per day versus expected maintenance costs.
