Water tap route?

I went out for a run late this afternoon. Perhaps a bit too late to take any good blips, but I thought you would like to see this signpost.

I ran through the wood behind the house and up to Bonaly via White Hill. Just before entering another wood I saw this sign on the way to Torduff and Clubbiedean Reservoirs. By the time I got to the far end of Clubbiedean, it really was getting dark and I didn't have my head torch with me. So a quick run down the hill to Bonaly (I saw several bats on the way) and home by the streets of Colinton.
