Water Pump

The water pump is a structure in Idle Tower Builder. It is used to regrow the forest where you get wood. However, it will not pump water when the water basin or basket is empty. You can combo this with the water extractor and you may have an endless supply of water.

Trivia
You can only have 1 water pump

Sometimes, if the lumberjacks are cutting too many trees, it will look like the pump doesn't work
