EPA Waste Water Discharge Licences

What is waste water?

Waste water is generated in our home and businesses from showers, toilets, sinks, washings etc. It is collected in a network of pipes known as a sewer system and conveyed to a waste water treatment plant for processing.

How does a waste water treatment plant work?

Firstly the waste water arrives to the treatment plant from the sewer network. Debris such as rags and grit are removed using large screens. This screened debris is then sent to a skip and eventually the contents of this skip will be sent for landfill.

The screened waste water then passes into large tanks known as aeration basins. This is where the biological treatment of the waste water takes place. In these tanks naturally forming microorganisms breakdown the waste in the water, in turn cleaning the water.

This mix of clean water and microorganisms then naturally separate in large tanks known as clarifiers. The clean water then flows out to the river and the microorganism are returned to the aeration tank to treat more waste water.
