Hornsby Bend
  • UPDATE: 5/15/2020
    Hornsby Bend Phased Reopening – Phase One - as of today Friday May 15, 2020, the Hornsby Bend Biosolids Management Plant will begin reopening to visitors. Today Platt Lane and the River Trail will once more be accessible to visitors.

    All visitors must follow City of Austin guidelines for masks and social distancing on our site.

    At this time, our main gate will remain closed to the public. In the coming weeks, we anticipate allowing visitors through the main gate for access to our treatment pond area as part of Phase Two reopening.


The Hornsby Bend Biosolids Management Plant plays a key role in sustaining Austin’s environment by recycling Austin's biosolids and yard trimmings. Hornsby Bend is also nationally known for its biodiversity, ecotourism, and one of the best birding sites in Texas.


The biosolids recycled at Hornsby Bend get mixed with compost and yard trimmings and turned into an EPA-certified soil conditioner called Dillo Dirt™. Dillo Dirt is donated to landscape public places and sold through commercial vendors.
