August 2, 2018

In June we completed the design and installation of a bridge mounted swiveling dry fire hydrant on Calvert Road in Cecil County, Maryland. The installation was the second of its kind in the Rising Sun area and the second along North East Creek. The creek provides ample water supply in the area and Chief Donald Wehry and the folks at the Community Fire Company of Rising Sun like the swiveling design because of the rapid deployment and limited need for suction hose. The Calvert Road bridge is owned by Cecil County...thus approval was needed from their public works folks before installation could begin. On June 15th, we conducted a deployment and flow test and achieved a flow of 1,192 gpm using CFCRS's Engine 813 (2000 gpm) supplying a Hose Monster flow diffuser with fixed pitot.

The installation used an ETT suction head (6" NST male) and an ETT stream strainer. Attachment to the bridge used the GBW Angle-Mount design.
