Brazilian Bugs from the other side of the world have been imported as a new approach to clean wastewater near Birmingham.
These pea-sized helpers have a large appetite for ammonia, which is produced when the body eats and drinks and comes out when you go for a poo or a wee.
Therefore, the ammonia-eating bugs are excellent for removing it from wastewater, which is produced from things like flushing toilets, sinks, bath tubs and showers.
As a result, these bugs will help water company Severn Trent Water treat sludge from a population of nearly 2.5 million people!
And it's eco-friendly too - according to the company, the Brazilian bugs have already contributed to a 15% reduction in power usage, as it reduces the amount of energy needed later on in the sewage treatment process, before it ends up in our rivers.
The project manager of Severn Trent has said "This approach has reduced our operational costs and (our) carbon footprint".
However, it is not just bugs from Brazil who are helping to clean our water, as Severn Trent have also recently used bugs from the Netherlands who they say have been just as helpful.
