Mayor's Conservation Challenge

April 1-30, 2018

Castle Rock residents have proven their commitment to water conservation. Now, it’s time to show the nation how much we rock! Mayor Green invites all residents of Castle Rock to take water conservation to the next level by taking a quick, online pledge to conserve more! 

Castle Rock’s involvement in the national Mayor’s Challenge began in 2016 with outstanding results. Castle Rock’s city ranking, based on the number of pledges, has made it to the top ten both years! This year, Mayor Green wants to get to first place.

Throughout the month of April, join us in taking a free online, pledge to conserve. Simply click on the pledge button below. With every pledge we increase our national ranking showing how water-wise we are. Help us get to first place in our division, and you could win incredible prizes! While prizes are available from the Mayor’s Challenge sponsor, Wyland Foundation, our ultimate prize is water savings. 

Take the Pledge!

Today’s rank: No. 7

We are ranked according to where we stand in relation to other communities in our population category. This ranking can move throughout the month!

Just a couple of actions your pledge encompasses:

  • Fix a leak 
    An American home can waste, on average, more than 10,000 gallons of water per year due to running toilets, dripping faucets and other household leaks. That adds up to 1 trillion gallons per year — the equivalent of annual water use of Los Angeles, Chicago and Miami combined! Pledge to fix those leaks.
  • Slow the flow
    Installing high efficiency shower heads can save 754 gallons of water per year, along with installing faucet aerators and low-flow toilets. Want a starter kit? Stop by Castle Rock Water (limited supplies available.) Pledge to slow the flow.
  • Smartscape your yard
    Approximately 50 percent of water used by Castle Rock residents goes to watering yards. Use native plants, reduce turf and incorporate hardscape designs. Simply changing your landscape can save time with less care (i.e. mowing) and money with less water and chemical use. Learn how at our free Water Wiser Workshops. Pledge to Smartscape.
  • Sprinkle the right way
    Sticking to early morning or evening watering times minimizes an estimated 20-50 percent of evaporation due to heat, wind and solar radiation. Rotary sprinklers and drip lines are better at getting the water to plants. Pledge to water the right way.
  • Don’t place trash in the toilet
    Less flushing means less water usage and less waste for the water reclamation plant to process. Place tissues in the trashcan, not the toilet. Take pharmaceuticals to designated drop off locations. Give ‘Bubbles’ the pet goldfish, a proper burial in the backyard. Pledge to dispose of waste properly.
  • Refill your water bottle
    Not only will you eliminate an estimated 167 plastic water bottles (per person) in the landfill, but you'll also reduce waste in your wallet. If you drank the recommended eight glasses of water a day, at U.S. tap rates equals about $.49 per year; that same amount of bottled water is about $1,400. Plus, Castle Rock Water won best tasting water in the region in 2015! Go ahead and fill up a glass. Pledge to refill the water bottle!
