Plumbing System Elements/Piping Systems In this two-story building, there is a pair of stacked restrooms. The men's restroom has 3 toilets and 2 urinals, while the women's restrooms has 5 toilets. Both restroom types have 5 sinks on the opposite wall. The stacked layout allowed for a simple set of trunks to service both floors similarly. There are 3 sets of trunks: two to service the sinks, one to service the back to back toilets.

I decided to implement a greywater system to improve the water sustainability of the building. With the sinks on the opposite wall of the toilets, I avoided the need for parallel sanitary and greywater pipes within the same mechanical space. The sinks drain into the greywater collection pipes, and the toilets receive their water supply from the greywater supply pipes. The greywater system is depicted in purple. The tank/connection between the greywater collection and supply systems is not explicitly modeled.

Pipe Types:

  • Sanitary (green)/Greywater collection (purple) pipes — 4" Dia. Pipes with 1/4" per 12" slope.
  • Cold water (blue)/ hot water (red)/ Greywater supply (purple) pipes — 1" Dia. Pipes

Design Challenges

  • While I had originally modeled the space for the pipes between the two bathrooms, I needed to add the space behind the sinks, which required some additional model coordination with the Arch. model and the Struct. model (some walls are structural walls).
  • Avoiding conflicts between pipes by adjusting heights and staggering plumbing elements.
  • Making changes to the HVAC system because of interference with the pipe trunks.
  • Ensuring no clashes between the pipes and structural system. The beams underneath the bathrooms run parallel to the pipes, so I verified that none were clashing with the pipes.
