Introduction
Description
- Greywater Outlet
During renovation of the CCAT house, plumbing was designed to divert greywater from blackwater; making it easier for the future greywater project. This outlet is located 3 ft beneath the ground.
- Sedimentation Basin
The basin is composed of a 50 gallon drum which was aquired through the Campus Recycling Program. Inside it (niki/drawing?). It is located directly next to the outlet, the top of the 3 ft barrel is 2 ft below ground level.
- Pipe to Marsh
A 27 ft long, xx in wide pipe was needed to pipe the water from the Sedimentation Basin to the Surge Tank. The reason why these two components are so far apart is because a driveway needed to be built between the outlet and the marsh site.
- Surge Tank
Need surge capacity. how much? gallon?
- Gravel Marsh
The actual treatment area is 4 ft wide by 14 ft long by 3 ft deep. Because this system was built on a hill, we had to dig even deeper than 3 ft to make up for the slope. we decided that 2 lower baffles and 3 upper baffles would suit our treatment needs.
History
Construction
Detail
- Diverting Greywater
Dug a hole by the house greywater outlet for the sedimentation basin to sit in. We had the building plumbed this way so the greywater was easily diverted
- From the House to the Marsh
Dug a trench from the outlet to the marsh location. 3 feet deep and feet long. Some was already dug the previous semester.
- Extra Plumbing
Layed inch piping and inch sleeve in the trench because a driveway needed to be built over it.
- The Big Hole
Dug the shape of the marsh and surge tank hole (located between the trench and the marsh itself). We decide that based on the slope of the adjacent hill, we would need to dig a hole 5 feet deep in order to have a marsh 3 feet deep. we dug 10 feet long and 4 feet wide.

Special Thanks
Special thanks goes out to all of the lovely volunteers we had at CCAT every Friday, the CCAT Co-D's for being so patient and supportive, everyone who helped with the design and construction of this here marsh, Nathan Chase, the Engineering 305 class, Miller Farms, HSU Plant Operations, thanks to bullrushes, wheelbarrows, shovels, rice, chocolate and water. This project simply couldn't have been possible without this wonderful, supportive community.
