Holidaypark Grevelingenpolder

Thanks to the use of wadis and plants that retain a lot of moisture in the soil, optimal use is made of rainwater and the use of tap water is prevented.


Solar collectors; heat pump boilers and rainwater storage tanks

At a campsite a lot of (warm) water is needed every day, because everyone wants to be able to shower and wash when they are camping. At a campsite such as the Kreekebos campsite, about 2000 liters of warm water is needed per day. To reduce the burden on the environment, they have therefore invested in solar collectors and heat pump boilers.

Camping 't Hof Bellewaerde has had a phytoparking installed by Rietland that purifies black (32m2) and gray (44m2) waste water separately.


Water Saving Shower Heads

Everyone flushes 130 liters of dirty water every day. This water disappears through the toilet, sink and shower drain. Water is saved by means of, among other things, water-saving shower heads.


Water savings

The London Heathrow Marriott saved 1.7 million litres water per year by opting for an on-site laundry
