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: Does Aquadapt software replace my operators?

Oct 19 2010

A: Definitely not! Aquadapt software is like an Auto Pilot which carries out the millions of calculations required to achieve a good mass balance in your supply system for lowest overall cost. This frees up the operators to concentrate on the daily tasks such as shut-down scheduling, maintenance planning, plant load balancing, water quality testing and any one of the thousand and one unique things that pop up each and every day in a complex real world system.
