water harvesting at a popular dog walking park

When we can't be bothered going far from home, we love walking at Chelsworth Park. We can walk around the sports ovals with Penny running free, but if we head off into the network of paths through the bushland along the Yarra River, Penny stays on lead.

We enjoy both types of walking.

Sometimes in warm weather we've seen dogs swimming in the new pool there. I do wonder whether it's safe, in terms of water quality and in terms of the grid across one end of the pool. I'm the sort of person who's always looking out for possible dangers.

Today when we arrived at the park, we saw some explanatory signs that we found really interesting. They explain what the pond is really for. We did know already that under the sports ovals there is a huge network of pipes to collect and store rainwater, and that the pond had something to do with it.

So, now we know to stop calling it a 'pond' and refer to it as a sedimentation basin. It seems to me that the water should be relatively clean, because the trap will have already caught the rubbish from the street stormwater drains.

But as to whether Penny should  swim there, I'll have to wait until we get more information about whether it's allowed. There's no sign forbidding it, though, and the water would only be rainwater.
On the other hand, the cement path leading down to it isn't very inviting.

I've wondered why the second pool rarely has any water in it, and now I see that it's actually a rain garden, allowing the water to sink into the ground.

It's amazing to think of so much water being collected and stored under the grass.

What a fabulous initiative! Living as we do in the driest continent on the planet - hmm, maybe Antarctica is drier, but I think that's not the case - we value our water.

Very interesting. Glad they put up the signs to explain it all.

Lassie and Benbji, lucky you dogs have us humans to read signs for you so you know what's going on.
