Intressant reningsverk,
Som ung ingeniör jobbade jag ngt år på en liten firma, Arca-regulatorer, som levererade bl a till reningsverk.

Bilderna tycks visa ett ganska stort verk, med rötkamrar där man kan göra biogas om man vill. Det var ganska vanligt med dessa men nu håller man på och uppfinner rötning av avloppsvatten på nytt, så det blir väl någon dyr, stor försökanläggning byggd med EU-bidrag och med studieresor till attraktiva länder.

Sedan upptäcker någon att biogas är miljöfarligt....:-P
