WOW drains...

Well this is what is happening at the moment...

The people you can just see wearing the yellow jackets are putting in the pipes that will take all the rainwater that falls on the roof of the new school and put it in a big tank under the nursery playground. This is so we can use it to flush the toilets in the school. This will save the school money and help save the planet we live on.

This picture shows some of the other drains, these take away the dirty water after you have flushed the toilet! We didn't have space to do anything useful with this water so it has to go into a sewer and to a sewage farm to be made back into clean water. The the grey thing you can see is a manhole, it collects together several smaller pipes and puts them together to continue its journey.
