I recall when cpt was in the midst of their crisis and people were justifying their using water to service their pools and lawns by saying they were paying for it - they could do what they liked.
My FIL has a massive pool and redirects a number of drain pipes to try and top it up but it's never enough. I know he buys water from a service on a regular basis.
No increase between yesterday and today unfortunately. There was a mathematical error on yesterdays Kouga.
I have a large flat roof and only use a small section of it which makes the pool regularly over flow during the rainy season. The problem is the dry season where I need to add about 10kL per month to keep the pool topped up.
Pool blankets are a waste of money as they only last about 5 to 7 years and are quite pricey for a large pool.
Rainwater storage would be nice but the storage costs are way too expensive. Storing 100kl for the pool and garden would cost R150K+, take up a lot of space and be an eyesore. Underground water storage tanks are at least two to three times the price of tanks above ground and there are hefty installation costs to excavate and put in concrete plinths to prevent them popping out of the ground when empty. One would think that storing water would be a lot cheaper than storing electricity in batteries but that doesn't seem to be the case.
There are lots of good ideas but most of them don't scale very well in practice.
