Abstract
The Sanctuary in Arcata, CA is a community building dedicated to offering a creative space where members of the community can grow, create and build not just physical things but experiences and memories as well. The Engineering 215 class of fall 2016 were given a number of projects to enhance the Sanctuary and make it more environmentally friendly inside and out.
There should be an image near the top.
Background
Before the new grey water filtration system, residents of the Sanctuary would transport their unfiltered kitchen sink water using a bucket. They would wait until the bucket was full, then carry it around the house to the garden in the back. There they would pour the unfiltered grey water onto the plants. Now residents of the Sanctuary can water the garden using filtered, reused water from a hose.
Problem statement and criteria
The objective of this project was to reduce the amount of city water that the Sanctuary uses outdoors. Our system filters the kitchen sink water from the neighboring house allowing the Sanctuary to use recycled water for outdoor use.
| Criteria | Importance | Constraints |
|---|---|---|
| Aesthetics | 10 | People need to be inspired to want to replicate this project. |
| Reuse of materials | 9 | 90% of the materials used must be reused or up-cycled. |
| Cost | 8 | No more than $400 may be spent |
| Maintenance | 7 | The system needs to be able to be maintained by 2 adults. |
| Ease of use | 6 | The system needs to be able to be used by any adult. |
| Safety | 5 | Humans may not come in contact with the grey water. |

Discussion and next steps
- Connect the grey water system to the drain of the sink inside the house.
- Attach a garden hose to the overflow water outlet of tub 2 so plants can be watered with the grey water in the system.
- Allow the roots of the plants in grey filtration system to grow to better absorb nutrients in the grey water
- Use the system to inspire spectators in ways to conserve water and live sustainably
