The Passive treatment design workshop was developed for a technical audience with experience in water treatment. A strong understanding of undergraduate inorganic chemistry will be helpful.

Overview Passive Treatment Systems Hydraulics

This section will focus on the hydraulic theory behind controlling water flowing in and out of passive treatment systems. This section will include a thorough discussion on the hydraulic theory behind using manually-activated piping systems and automatic siphons to flush precipitate from treatment systems.



Kim Weaver, P.E., is a project manager at Hedin Environmental, a small
Pittsburgh PA consulting firm specializing in mine drainage assessment
and treatment. As an undergraduate civil engineering student at
Bucknell University, she assisted Dr. Carl Kirby with mine drainage
research. She obtained a master's degree in Environmental Engineering
from Princeton University. Ms. Weaver has worked at Hedin Environmental
since 1999.
