Water supplier ontology I am new in this world, I am going to start working on my final degree project about data mining. I need to look for an ontology related with water supplier companies.

I mean, I have words like: SuppliedWater, RegisteredWater, LengthSupplyingNetwork...

I am looking at lod-cloud, but I don't know where to start looking for this.

Any help would be appreciate.

Thanks for your help.
I finally used this website, since I found it easier to found any ontology.
For example I found this one, very similar to what I was looking for.
