I thought to start by investigating Victorian infrastructure, and have discovered a small gold mine of information that I didn't know, woo !

One of these was name of the engineer that built the sewer system during the time, Mr Joseph Bazalgette (pictured). I remembered a TV program 'the seven industrial wonders of the world' which included his construction of the sewers but just couldn't remember the name of the engineer until now.

The other information I also discovered that London had a open sewer which caused mass outbreaks of cholera and other diseases through out London.

From this information I have discovered that for our environment it would have to be pretty grimy if we did the back alley before the sewer was in place.
