This deliverable includes the box design made in CAD. Sides will be made of treated plywood sheathing, with one side being a plexiglass sheet for a view of the filtration layers. The box will also have a plywood slope to drain the water into a PVC pipe, covered with hardware cloth. The sloped plywood will be supported by 2 x 4s. There will also be 2 x 4s on the outside of the box to support the build.
