We have a wetting agent programme, which essentially is something we can spray into the soil. It sounds like a weird term, but it makes water wetter. When you think a soil is really, really dry, our grasses can still get water that is maybe not available to other plants.
"The city of Austin has been doing a fantastic job with water conservation, and we are using less water per person than we were 20 years ago ... but the concentration of the wastewater has really increased. Low-flow toilets and washing machines are all great, but that's more waste and dirt and less water that comes to our facility."
