Water Quality

Water Quality & Aesthetics

Here at Rox Water we not only take the safety of your tap water very seriously, we also care about its overall quality.

Testing Your Water

The District’s certified and highly trained water specialists regularly monitor, test, and ensure our water quality and treatment processes meet the requirements of the Colorado Department of Public Health and Environment, which is the State’s water quality regulatory agency. Below are our most recent reports on Roxborough Water’s quality.

Fluoride: We do not add any fluoride to the water we purify and distribute to our customers. There is a little, naturally occurring fluoride in our raw water. You can see this reflected in the reports below.

Water Hardness: The hardness of RWSD Water is considered moderate. It is measured as 100 Milligrams per Liter or 5.8 grains per gallon.

Water Discoloration

Water discoloration in our area is common due to naturally occurring harmless minerals (primarily iron and manganese) that can collect in water pipes. Like many Front Range providers, we conduct system maintenance (flushing) each spring or early summer to address this issue.

Your water remains safe to drink, but the District does not expect you to use the water when it is discolored (especially for laundry, as it could cause staining). If you notice discoloration, contact us at any time 24/7, and we will send out a field technician to flush the pipes and ensure water to your home is flowing clearly. Once our field technicians have completed the flushing of the system, you should open the cold water on a tub faucet at the highest elevation point in your home and let it run clear to flush the service line and your homes internal plumbing. You may also want to drain and refill your hot water tank (in accordance with manufacturer warning and safety instructions).

Let us know right away if you experience any water discoloration or have any other water clarity concerns by calling our office at 303.979.7286, Option 2.

Testing for Lead & Copper

Twice a year, every year, we test the water at 60 volunteer homes for lead and copper. The homes were selected because of their location and their construction date. The ongoing study helps ensure the water quality in the Roxborough community remains safe to drink. Specifically, that no lead is being introduced into the tap water from any internal pipes.

While the District’s main pipelines and treatment process do not introduce any lead into the drinking water, it can enter tap water as a result of corrosion from lead used in water pipes found in older homes. That’s why the EPA and state regulators have required all public water systems to test for lead and copper at the faucets of specific homes. To date, there haven’t been any reportable levels of lead due to internal pipes.
