Achieving Enlightenment in a Flawed World: How to Create Useful Collection System Models from Deficient Monitoring Data

When it comes to modeling, it is said that "garbage in equals garbage out." Still, model calibration depends on real data and its inherent imperfections. Obtaining useful information from significantly flawed data can be tricky, but it is not necessarily a lost cause. Several case studies demonstrate how even deficient flow monitoring data can provide significant information about collection system behavior and serve as a solid foundation for developing a collection system model needed for compliance with wet-weather regulatory requirements.

Amy Post, P.E. - Symbiont

Ms. Post has been an engineer and project manager with Symbiont at its headquarters in Milwaukee, Wisconsin since 2003.  She is responsible for the execution of collection system evaluations for wastewater and storm water facilities including modeling, long-term planning studies, and field studies.  She also designs relief sewers, lift stations, and low impact storm water conveyance and treatment systems.  She has a bachelor’s degree in Civil Engineering and a certificate in Environmental Studies from the University of Wisconsin – Madison.  She is a registered Professional Engineer in Wisconsin and an active member of the Wisconsin Collection Systems Committee, although she has spent most of her career doing projects for communities in Illinois.

Pavel Hajda, Ph.D., P.E. - Symbiont

Dr. Hajda’s professional career in wastewater treatment engineering spans two decades and both sides of the Atlantic. From Europe, he brings the Bachelor’s in chemical engineering (from the Institute of Chemical Technology in Prague) and several years of consulting practice in modeling and preliminary design of municipal wastewater treatment plants with nutrient removal. This was the early 1990s, when much of Europe began to contend with the eutrophication of the coastal waters, including by regulating nutrients in urban wastewater effluents. Stateside, Pavel obtained his Master’s and Ph.D. in civil engineering at Marquette University in Milwaukee, registered as a P.E. in Wisconsin, and gained a decade’s worth of practical consulting experience in Illinois as a process engineer mostly focused on municipal wastewater treatment planning, permitting, design, and construction engineering. Increasingly, these Illinois projects began to include nutrient removal features, usually driven by third-party concerns with antidegradation and the interim effluent standard for phosphorus.
