Design Journal Entry - Module 10

• your plumbing system elements

I placed one toilet and one lavatory sink in each room because of the space constrains. For each men’s room, I also install a urinal.

• your piping systems

I designed cold water, hot water, sanitary, greywater collection and greywater supply systems.

Considering the number of toilets and urinals, I chose 5” Copper - K for main sanitary pipe, and 4” Copper - K for horizontal pipes.

• any special plumbing system challenges that you encountered and how you overcame them

To install plumbing system, I made some space by putting new interior walls in restrooms because the walls next to restrooms are structural walls and difficult to penetrate pipes. I was not able to make enough space to coordinate sanitary pipes connecting to one vertical pipe. Therefore, I decided to place two vertical lines for sanitary and greywater supply.
