The Battery Pond

Tenji, Inc. designed an outdoor pond system for The Battery in San Francisco, CA.  The Battery is an exclusive club with dining, wine tasting, a state-of-the-art fitness center and rooms and suites for it's members.  The pond is an 8000 gallon system that acts as a divider between two of the The Battery's buildings.  A bridge allows members to walk over the pond and enjoy the koi.  Tenji worked with Waterdog Products to design the fiberglass tanks that line the concrete ponds.  We designed the filtration system which incorporated Aquaculture Systems Technologies bead filtration and AquaLogic UV sterilization.  We drew the entire pond and filtration system in 3D to ensure the best use of space and proper function. The system was installed by local mechanical contractors and Tenji recently provided commissioning services.
