Minor adjustments to water rates and fees add up to big community investments


Securing the Town’s long-term water future; providing great-tasting, safe drinking water; and improving stormwater infrastructure throughout the community are all goals in the coming year for Castle Rock Water. As the department works hard to plan for the future, funding is always a consideration. To help accommodate the needs of the community, there will be a small change to Castle Rock Water customer’s bill in 2017.

The new rates – approved by Town Council – will have minimal impacts to customers but big benefits to Castle Rock, as the department works to secure the community’s future. Castle Rock Water’s annual rates and fees analysis determined residential customers can expect to see an average increase of about $14 per year. These additional funds will help further the Town’s long-term water program and fund needed capital improvements to the Town’s stormwater system.

Most of these changes will be seen in customer’s water usage charges. For some time, these charges have been based off a tiered system. The more water customers use, the higher tiered rate they would pay.

Tier 1 is based off a customer’s average winter monthly consumption. This average is calculated by dividing a customer’s total water used in November, December, January and February by four. This represents the amount of water for indoor use and the amount of wastewater treated each month. Tier 2 is the amount of water available for outdoor irrigation from April through October. Tiers 3 and 4 are considered excessive use tiers.

In the 2017 rates and fees structure, tiers 1 and 2 will see a small increase, while tiers 3 and 4 will experience a little more upward movement. This approach promotes conservation and encourages customers to take more control of their water usage.

Fee changes will also be seen in the stormwater fixed fee. This nominal increase will help pay for stormwater capital projects and increase flood protection throughout the community.

Lastly, system development fees will also be increased in 2017. These are the fees paid by developers to make improvements to our system and help fund our long-term renewable water plan. In the near future, these fees will help pay for expanding Castle Rock Water’s wastewater treatment capacity, additional stormwater improvements and implementation of the long-term renewable water plan.

Using financial projections, Castle Rock Water is working strategically to make sure any required rate increases are as small as possible to minimize the impact to customers. When compared to other Colorado communities in the area, Castle Rock’s water rates are about average. Keeping comparable rates, while still ensuring the community’s water future is a top priority for the department.
