Water and wastewater conveyance and treatment goes back as far as 1500 BC. What do we have in common with these ancient systems? How do these principles apply to today’s water and wastewater treatment? What can we learn from this historic knowledge?

During this workshop we will explore:

• similarities and differences of historic and current collections & distribution systems
• historic water and wastewater treatment principles and how they compare to today’s treatment approaches
• historic, current, and emerging concerns in water & wastewater treatment

Our LIVE ONLINE “Lessons learned from historic water & wastewater treatment” workshop will provide context to historically and internationally applied treatment processes and encourages class participants to evaluate how and why we utilize current treatment technologies.
