Where does  the Town’s water come from?

One of the Town’s more common queries from residents is regarding why their water bills amount to what they do.

Unlike some other municipalities in the area, Castle Rock sends water customers one bill for four services -- water, wastewater (sewer), stormwater (runoff) and renewable water.

This page, and the pages it links to, explains the four services.

Our water comes from wells – not the mountains

Many residents – especially those new to the area – might see the snow-capped mountains in the distance and think that water must be plentiful here. But that isn’t the case. Colorado has a semi-arid climate, averaging only 8 to 15 inches of precipitation a year. That means every drop counts.

Couple those dry conditions with the fact that Castle Rock is situated in an area where surface water (lakes, streams and rivers) is scarce, and that makes water an even more precious resource.

Because of its location, Castle Rock currently gets almost all of its water from aquifers, via deep wells. This is an expensive way to get water but for now is the only option available.

There are several components that make up a customer’s total water bill.

The water used by your household makes up only a fraction of your total water bill. That use is billed according to the Town’s water budget rate structure.

Your household’s wastewater cost also varies according to the amount of water used by those in your home. Read how that cost is calculated and what it covers.

Another component of your bill is the stormwater charge.  Learn about the stormwater charge.

And finally, there is a monthly fee associated with renewable water resources.
