Sarah the hardest worker who is always chuggin' away.
CCAT yurt rainwater catchment. The long history of rainwater collection, can be traced (in recorded history) as far back as ancient times some 3,000 years ago (850 BC) if not even farther. The need for water is a basic human essential for maintaining life, without it, no civilization could have prospered. Rainwater collection in ancient Constantinople is one of the last megalithic structures of its kind.

The CCAT Rainwater Catchment Group consists of: Sean Colley, Matt de Young, Jessica Radtkey, Sarah Shimizu, and Tiesha Whittaker. Our project for ENGR 114 was to build a rainwater catchment system around the yurt at CCAT on campus at Humboldt State University. The purpose of the rainwater catchment system is to capture and store rainwater in a large storage drum for use to water plants on the CCAT grounds. Water is a resource that is always present around us but not always in an immediately useful form. Therefore, it is necessary that we use innovative and appropriate techniques to capture and transform the water that we have into a useful form of water for our needs.

The mystery of language was revealed to me. I knew then that ‘W-A-T-E-R’ meant the wonderful cool something that was flowing over my hand. That living word awakened my soul, gave it light, joy, set it free.

Those who have health have hope, and those who have hope have everything.
Arabian Proverb

An individuals health greatly influences their ability to support themselves, provide for their family, and contribute to the community. Because of this, access to care and the health of a community is central to any development effort.

Unfortunately, health care is poorly distributed around the world. Southern hemisphere countries are much more likely to suffer from lack of access to care. One aspect of this disparity is the health technology gap between developed and developing nations. While developed countries continue to invest in high technology equipment, developing countries often lack the most basic health care tools. Appropriate Medical Technologies (AMT's) can help communities, governments and development agencies create simple, low-cost, and culturally appropriate responses to health care problems.

The use of appropriate technologies is less common in healthcare than other fields such as construction or agriculture. However, there is significant crossover between the public health field and the water and sanitation fields, areas that are more familiar with appropriate technologies. Appropriate technology is often used to develop mobility and rehabilitation equipment as well as tests used to diagnose diseases.
