The three and a half mile Hornsby Bend, which is owned by the City of Austin, is also the home of Austin's Biosolids Management Plant, which processes two-thirds of the city's solid waste. From tap to toilet, Anderson explained how the city disposes of waste water and how what we see as sewage can be sterilized and recycled into compost rather than being dumped in landfills. Even urban water systems have a unique ecology that must be carefully managed.
The take-home message: even urban areas have unique ecologies that are constantly changing and adapting to climatic and human pressures. All one needs to do is take a close look around to see that not all is in fact lost.
