The Hornsby Advocate wrote last week about a brilliant new stormwater management plan by Hornsby Council to filter stormwater & water street trees at the same time.  Hornsby Council will install 3 tree-pits. These tree-pits capture stormwater from specially installed gutters. The stormwater is then filtered through soil, sand & gravel.

It’s such a simple idea, one wonders why this technique hasn’t been used before & why it isn’t put in place with all new street tree plantings. It would certainly go a long way to preventing tree deaths due to lack of water.

The paper published a diagram of the tree pits. Unfortunately I can’t post the picture here due to copyright, but it is well worth a look.

New footpath in Canterbury LGA & not one street tree planned. A cement desert.
