Fill the Rock with water savings and win prizes!

Each small step toward conservation adds up to big savings and a win for all of us. Throughout July, Castle Rock Water is asking residents to take daily actions to conserve water. 

Each action will be used to ‘fill’ Castle Rock with water savings. Register your conservation actions at and be entered into weekly drawings for prizes totally more than $800!

Prizes include:

  • passes to the MAC
  • trampoline time
  • cool water bottles
At the end of the month, all entries will be eligible for the grand prize of a smart irrigation controller valued at $200.

To "fill" the Rock, we will need to log 1,577 actions. We have arbitrarily assigned each action worth 1,000 gallons of annual water savings. If we could "fill" the Rock with water, it would hold 15,770,000 gallons of water! Can we Fill the Rock in July? Help us try!
Visit to find the daily conservation actions, weekly registration forms and a list of prizes available for the random drawing.
