Template:305 CCAT Rainwater Upgrade

Background

The rainwater catchment system at Humboldt State University’s Campus Center of Appropriate Technology was created in 2008 and revamped by an Engineering 305 group in 2014. However, the rainwater catchment system is currently not in commission due to several factors such as overflow issues and tank cleanliness which means perhaps redesigning the system. In order to update the current system it may mean resizing, labeling, gutter screens, testing, cleaning, and pumping parts. The Campus Center of Appropriate Technology is a learning center for students and community members to learn and share practices of sustainable living so it is valuable to showcase a rainwater catchment system. The rainwater catchment system will also allow for an emergency water source and decrease in a water bill for the Center.

Problem statement

The objective of this project is to recreate the rainwater catchment system through the use of recycled items and existing parts, in order to catch rainwater effectively.
