Located near the convergence of the San Antonio River and San Pedro Creek, Confluence Park is an initiative of the San Antonio River Foundation that transformed a former industrial laydown yard into an outdoor learning center that merges art and science to teach environmental science and encourage sustainable practices towards the river and all water sources.


The 116,300 SF Park includes a 2,400 Multipurpose / Restroom Building, a primary covered pavilion and three satellite pavilions of approximately 530 SF each.


The park design includes a water reclamation and treatment system for building water use. This system takes advantage of the rainwater collected from the pavilions and park hardscapes.  This specialized UV and filtration system significantly reduces the amount of potable water used by the plumbing fixtures in the park, with the exception of hand sinks and drinking fountains.  Additionally, a photovoltaic array provides 100% of the energy use for the project when measured over a yearly basis. The photovoltaic array allows Confluence Park to be an energy neutral space, eventually giving power back to the electric grid.
