BL Companies has been retained to perform Subsurface Utility Engineering (SUE) services at the Bronx Zoo for the design of a new Medium Temperature Water network. The Bronx Zoo has a cogeneration power plant where the domestic water gets heated and piped throughout the buildings at the zoo. Years ago, they had oil tanks at different areas of the zoo to heat the water through individual burners in the basements of each building.

BL Companies will be providing SUE services for tracing out the existing underground utilities using electromagnetic induction and ground penetrating radar.
