Sysco is the global leader in selling, marketing, and distributing food and non-food products to restaurants, healthcare, educational facilities, lodging establishments, and other customers. Sysco's Winter Garden facility underwent an expansion that resulted in the need for additional stormwater storage.

Space at the site was limited, so engineers decided to maximize what space they had by removing an above-ground pond and replacing it with an underground exfiltration system. However, engineers needed to address several challenges, which included a high water table, supporting heavy truck loading, and the large volume of storage required – over 12-acre feet. 

Both corrugated metal pipe (CMP) and plastic chamber systems were considered.  The CMP system offered a greater void ratio, which reduced the overall footprint while also significantly reducing stone quantities.  This allowed for faster, more efficient installation and lower material costs.  The reduced footprint and lower cover requirement of the CMP system also allowed greater site design flexibility to avoid conflict with utilities and accommodate low inlet elevations.

Pipe diameters were customized for the site. The system uses 54,000’ of 18”, 24”, 28”, 36”, & 42” perforated CMP. The system required no stone bedding, and only 12-inches of cover, resulting in 24,000 tons of stone savings.  

This installation is a perfect example of Contech’s variable diameter design strategy. This strategy allows engineers to select from 120 different pipe sizes to maximize vertical storage space, while the zero stone bedding and reduced minimum cover resulting in significant cost savings.
