water cycle<br />
& high-water<br />
efficiency<br />
By Mads Warming, Global Business Development Director for<br />
<strong>Water</strong> and <strong>Wastewater</strong> Business<br />
In recent years we have seen a few wastewater treatment facilities<br />
begin to get to the level of energy neutrality, based on energy<br />
generated from the digester.<br />
There are good reasons to work with these technologies as water<br />
and wastewater facilities is highly energy intensive. According to the<br />
International Energy Agency (IEA), four per cent of all electricity<br />
used globally is used just for the water and wastewater handling<br />
facilities. The IEA also states that approximately 30 to 50 per cent<br />
of local government’s electricity bill typically is related to the water<br />
and wastewater operation.<br />
Aarhus <strong>Water</strong> Ltd, a <strong>Water</strong> Service Company in Aarhus, Denmark’s<br />
second largest city, started a process over five years ago to optimise<br />
their water and wastewater treatment facility. There has been special<br />
focus on a catchment area named Marselisborg, covering 200,000<br />
people in the centre of Aarhus.<br />
