Dear whoever it may concern,

Can you confirm that from your EU Waste water treatment interactive map you have available that the 'waste water treated per year' figure for treatment plants is in m3/day (as indicated) as it seems too high. Is it meant to be litres?

Kind regards,
Fiona

Dear Fiona,

Thank you for your question and interest in the European Environment Agency (EEA).

The figures of reported waste water treatment is in m3/day.

The unit m3/day is available in the tableau output assigned to the map “Treatment plants – detailed” after clicking on the link “more information” in the pop-up window. On this tableau output, the attribute Volume of waste water treated (m3/d) is available on the second row.

As an example, we can look at the Central treatment plant in Prague. The volume of waste water treated for this treatment plant is 111,388 m3/day. Most of the urban waste water in Prague is treated by this treatment plant. Prague has circa 1,250,000 inhabitants. As assumed values, if the majority treated by this treatment plant is from 1,000,000 inhabitants and if the consumption of the water is 100 litre per person per day, then the treatment plant should treat 100,000 m3/day. This figure is consistent with the volume of waste water treated for this treatment plant at 111,388 m3/day.

If there is a specific treatment plant or area you are concerned about the reported figures of, you can provide us with the names and we can have a closer look.

Best regards,
EEA Enquiry Service

That’s a lot of sludge from all that waste water. Powerhouse Energy Group, have a technology to dispose of dried sludge. The process functions to the highest environmental standards taking sludge to synthetic gas, to electrical energy and if requirement road fuel quality hydrogen.

Powerhouse Energy Group, does attain the feat of energy from waste with virtual no toxic byproduct, no chimney, no incineration and a small footprint of 4000sqm.
