Natural processes in drinking water production Amsterdam
Artificial recharge in dunes
t = 100 days
Loenderveen basin
t = 100 days
The source for sewage
• That drinking water:– is used to transport wastes
– is mixed with rain and groundwater
• This mixture:– is called waste water
– is a problem and costs a lot of money
+ rain…..

Mixing zone European Union• Discharge of treated waste water to receiving surface water
• Mixing zone allows discharge does not meet quality of receiving water
• Waterharmonica takes the EU‐mixing zone out of the EU‐water body
• Efffective means to meet the EU‐standards
Most important result:nature !!

Reasons to make Waterharmonicas – until 2001
No. Name Primary reason/reasons for construction
0 Elburg 1978: to lower the nutrient level in STP effluent, taken out of operation. Has not been put back into operation because of the ‘high natural values’
1 Everstekoog, Texel
1994: as a source of fresh water for agriculture on the island, disinfection because it crosses a residential area. Has been expanded and renovated in 2012 – 2013
2 Empuriabrava, Spain
1995: to supply water for a nature reserve/to create local natural value
3 Klaterwater in Kaatsheuvel
1997: to produce water with a low level of nutrients and pathogens for the Efteling
4 Tilburg-Noord 1997: to buffer effluent during rainwater discharge so as not to exceed the maximum permissible effluent rate because of the limited capacity of the stream de Zandleij, ecologisation at basic discharge
5 Land van Cuijk 1999: to supply water to agriculture/nature and to reduce discharge to national waters
6 Sint Maartensdijk
2000: to reduce nutrients and obtain insight in the functioning of the helophyte filter, recreation
7 Waterpark Groote Beerze
2001: river restoration Groote Beerze, to promote wet habitats
- Nutrient removal
- Buffering water
- Supply water for
agriculture, nature

Result on suspended particles / solids:• Elburg (1978) and Everstekoog (1995): SSout more or less equal
to SSIN, or even an increase !
• Recent six constructed wetlands: same

The Waterharmonica is very effective in reducing peak pollutions of eg. a sludge overflow:
• Both Suspended Solids (90%) as P (90%) and N (60‐70%)

EcotoxicologyThe Waterharmonica:
• Effluent from STP can have an inhibiting effect on algae development
• WFD innovation project WIPE showed: • Waterharmonica has a favourable effect on the toxicological
quality of the water in the outlet (possible by adsorption, degradation or smoothing peaks)
• No indications of risks of acute toxicity
Ecotoxicology
WIPE research on:
• Xenobiotic substances (passive sampling)
• In‐vivo bioassays– Bacteria (30 min)
– Algae (72 h)
– Zooplankton (48 h)
• Fish
