[edit] Water Goal
Closed loop water cycle. Self-sufficient in water.
[edit] Water Ideas
[edit] Collecting Water
- Dew collection
- Rain water collection
[edit] Water Efficiency
[edit] Showers
- 1.0 gpm showerheads (or less!)
- Ability to easily stop water to lather and then turn back on flow without need to re-adjust water temp for shower/faucets
- Showers that don't lose there steam too quickly so that turning off the flow would not compromise comfort
- Recycling showers that filter water
- Shower drain heat recovery
[edit] Toilets
- Composting toilets
- Low flow toilets
- Reclaimed water toilets
- Waterless urinals
- Urine separating toilets
[edit] Greywater, Blackwater, Pollution
- Organic, biodegradable soaps and detergents a must for the greywater system
- Can provide them free for use in the dorm
- Living Machine, visible water treatment in garden form
[edit] Flexibility
- Easily accessible pipes throughout the building
[edit] Using Water
- Waterfall for evaporative cooling
- Radiative cooling
- Cooling tower like Carnegie
[edit] Unsorted Ideas
- Grey water filtering/reuse for landscaping
- Permeable pavement on site
- Membrane bioreactor/ closed loop water system
- A shower stall that could easily be modified with different shower stall technologies (ie different shower heads, a recycling filtering shower)
- Collection of dew that naturally occurs because of the day and night temperature differential
- Fuel Cell/Energy Generation H2O recovery
- Rotating shower head tester (Issue: people might just choose a higher flow shower head all the time)
- Preloaded washing machine
- Panel in each bathroom with easy access to pipes to install/adjust usage and flow rate meters
- Real time metering and monitoring of the shower, with LCD panel in shower
- Automated soap/water
- Water usage meters on sinks with warning if over average use
- Need large water storage and treatment capacity, for potable water, greywater, blackwater
[edit] Water Questions
[edit] Solvable

- Answer: ?????
- What is the Santa Clara county policy with regard to waterless urinals, grey water, and other innovative water solutions?
- Answer: ????? (Probably the design team will be able to answer this one best)
[edit] Depends On Many Things
- How many water storage tanks do we need for various purposes, and what should the capacity be?
- Answer: ?????
[edit] Debatable
- What kinds of toilets should we have? (Low flow, reclaimed water, urine separating, waterless urinal, composting?)
