We have a 20,000 litre rainwater tank that serves our house for drinking and other water. Since it was last filled by tanker at the start of November 2023 we've had only about 175 mm rain (6.9") adding ~11,000 litres. That's just not enough, so today the tanker delivered another 12,000 litres.

Tanker at the gate.
The tank is very low.
Nearly full tank.
