MWH Thornton Reservoir_rebuilt

A feature article on the successful completion of the Metropolitan Water Reclamation District of Greater Chicago’s (MWRD’s) Thornton Composite Reservoir project appeared in the July/August 2016 issue of World Water Magazine. World Water is the official international publication of WEFTEC, reaching more than 23,000 readers around the globe.

MWH, now part of Stantec, has been serving as the Design Engineer since the inception of this project in 2007 and has played a multi-faceted role, including mathematical modeling, detailed design, cost estimating, and assistance during construction. Key elements of the project designed by MWH include a 112-foot tall roller-compacted concrete dam, a 1,300-foot long, 30-foot diameter connecting tunnel, and related gate structures.

This project, which is the world’s largest combined sewer reservoir, is constructed to hold 7.9 billion gallons of water, eliminate pollution from local waterways, and reduce the risk of flooding in tributary areas. It benefits 556,000 people in 14 communities throughout the South Side of Chicago and south suburbs.

The Thornton Composite Reservoir project is also being featured in the WEFTEC 2016 International Knowledge Exchange (IKE) taking place in Room 239 of the New Orleans Morial Convention Center on September 27, from 8:30 a.m. – 12:00 p.m.
