SEWAGE
SISTERS
The study of limnology (fresh water from the earth’s surface) was an important
aspect in the class of Advanced Biology. By understanding the concept of limnology,
the students of years past were required to know all that was needed in dealing
with sewage treatment. Each year students designed projects to study; in hopes
of someday their ideas would be used to help mankind and his environment. The
students had learned that the Cascade Reservoir was suffering due to the process
of eutrophication, (aging of the lake by excess of nutrients, water becoming
more shallow, plant overgrowth) or in this case, cultural eutrophication, being
that the lake is man made, this process has occurred more rapidly than that
of natural lakes. Among the individuals who worked on the water treatment, four
students who claimed themselves to be the “Sewage Sisters,” were
determined to fix the problem. Finding information from a small article in a
“ National Geographic” magazine, the article featured a British
company called Biotechna. The article praised about a new sewage system, one
that looked promising. It was called the Biocoil.
