Piwoslaw's rain water system (underground tank)

[Piwoslaw]

Not really that large! During summer heat waves and droughts, watering the lawn can easily use more than 600 liters per day. And last summer the tank did indeed go dry, so we had to use city water for a few days before we got some rain.

But not having to use potable water for lawn and toilets for the rest of the year is a great feeling!
