water resources
our expertise
With increasing frequency, clients remain challenged with improving the management of our impervious environment. With today’s climate change challenges, cleanliness, availability, and quality of water is of paramount concern. Our team of engineers and technicians provide innovative, cost-effective solutions and recommendations for a wide range of water management systems and improvements, including the design of reservoirs, dams, and levees. The management and design of drainage systems for stormwater runoff and the systems needed to manage runoff in an environmentally sound manner is a critical component of almost every site/civil engineering project. With a focus on safety, constructability and lifecycle costs, Patrick is proud to meet these challenges with value-added solutions.

our projects
Chicago Department of Aviation (CDA) | Bessie Coleman Water Main Project
Patrick provided professional engineering services to the Chicago Department of Aviation (CDA) for the Bessie Coleman Water Main Project at Chicago O’Hare International Airport. This project included all tasks necessary to design approximately 1.4 miles of new water main along Bessie Coleman Drive, Schlitz Road, through the Airport Transit System (ATS) and parking lot areas, and in the area east of the Signature Fixed Base Operation (FBO) building. The new water main replaced an existing water main that was either at the end of its service life and/or is not in a desirable loop configuration. The CDA did not implement the design when initially completed and put it out to bid several years later. Additional airport improvements had been constructed in the intervening years and 5,000 feet of additional water main were added to the scope of the project. Necessary design changes were fast tracked and run concurrently with the bidding and construction of sections of watermain that had not been affected by changes in order to prevent delay of the construction schedule.
