Royal Water

Last summer I visited Royal Brewery Grolsch in Enschede with my brothers in law. [not mentioning them will fill the comment box below…] They were proud to pronounce producing environmental friendly. They rebuilded the factory in 2004 on a different location, so they could make it ahead of the future.

It might be well known the Netherlands has no shortage of water at all. It’s in our name and gravity makes water run to lower parts. But … Grolsch didn’t want to waste water. In 2015 Grolsch wanted to reduce 25% of it’s water consumption. Not including the water to make beer from, most likely the want these results up with 25%. Grolsch sat its target for 7 years.

Since it was a rainy day, I asked the tourguide what they did with rainwater? Although he knew all the ins and outs of his factory he couldn’t give me an answer. They just let is flush away?

Made me wonder … what do factories with sky water and since we were talking about the topic earlier this blog what does the paperindustry do with all its water? They claim to be enviromental friendly but how do they use their biggest gift of nature: water?

Case studies show that in Renkum’s township there are two main purchasers of water: Vitens and Parenco. Vitens is the water company and Parenco a paperfactory. Do not be mistaken: the factory is allmost as big as the town itself.

So this weeks quest would be; what do they do with their rainwater?

Because the other grazy thing is: the municipality of Renkum transformed its underground water infrastructure completey. They opened up streets to set other parts under water during rainy days, so called wadi’s. Kids started complaining for it was their playground and parent thougt is was sewage water…

Which it wasn’t, it just got a little dirty from running over the streets.

So they opened up the wadi’s and made an underground sedimentation system.

The idea was as very old, the implementation quite new. From the first days of using water as an energy source, the millers dug out brooks and springs. [AnnO 1600]


dig, duck, dug

The Dutch language provides words for these: Spreng or Sprang, these are menmade wells.

Although the Netherlands have enough water the land will dry out if all water effluxes.

What if we build factories which not only use rainwater, but purify it as wel? Take Ford for example, they drain water cleaner than it lands on their roof.
