Cobbs Creek Reservoir Construction Update

When completed, the Cobbs Creek Reservoir will possess a 15.5-billion-gallon raw water storage capacity within a 1,100-acre normal pool. Henrico County began this project in 2002, seeking to secure its customers’ drinking water needs for the next 50 years.

Schnabel commenced its role on Cobbs Creek in 2011, where we provided full design services for the 160-foot-high, 4,750-foot-long primary embankment dam, a 30-foot-high, 800-foot-long saddle dam and associated spillway, a 155-foot-high inlet/outlet tower, an outlet works conduit, and maintenance vehicle access bridges. Our services also include geotechnical engineering to support the design of the river intake, pump station, and transfer pipeline; bid support; full-time construction phase engineering; and monitoring and inspecting the dam during the first filling of the reservoir. Schnabel is pleased to be working with an excellent team that includes Henrico County and Arcadis. Construction began on this project in 2017 and the reservoir is expected to be fully operational in 2023.
