We strive to produce the highest quality water that is safe and pleasing to drink. It is important to us that your water be safe, clear and good tasting. It must also be delivered with adequate pressure and volume to meet other safety issues like fighting fires.

The Town of Dillon exceeded the lead action level three times in recent years (2012 and the first and second half of 2014). Because of the exceedance a new corrosion control treatment system was installed and put into operation January of 2015. The following first and second half samples of 2015 has shown a reduction in lead and copper contamination in the system and meet the requirements for sample reduction. But, due to the recent events with lead in Flint Michigan highlighting the importance of safe drinking water for citizens across the nation and brought long-needed attention to the complexity and implementation challenges with the lead and copper rule (LCR). Colorado Department of Public Health and Environment (CDPHE) did not grant a sample reduction and requested the town to improve the sample pool for higher risk sites in accordance with the lead and copper rule. Efforts to encourage participation from customers in single family homes (SFH) built between 1983 and 1987 with copper pipes and lead solder and then multi-family homes (MFH) and buildings built between 1983 and 1987 with copper pipes and lead solder. Which produced 13 sample sites between 1983 and 1987 (2 SFH and 11 MFH) and remaining 7 sample sites were single family residences from 1982 and earlier with copper pipes and lead solder.

The October 2016 results from the new sample pool sites produced four of 20 samples with lead concentration above the EPA action level of 0.015 mg/L with the 90th percentile at 0.026 mg/L. None of the samples exceeded EPA target levels for copper. To view that letter click here. To get more information on Lead see the EPA website here. The Town of Dillon encourages the distribution of the information to all potential affected customers and users of the drinking water system.

Adjustments to the pH target (8.15 to 8.5) within the distribution have been performed after receiving sample results. Additionally, the Town is in contact with CDPHE and our engineer consultant (HDR) to investigate additional alternatives to resolve the lead issue.

In 2017 the Town performed semi annual samples(June and August) both in compliance with 90th percentile rule. June sample results did not exceed the EPA action level of 0.015 mg/L with the 90th percentile results at 0.007 mg/L. August results produced two of 20 samples with lead concentration above the EPA action level of 0.015 mg/L with the 90th percentile results at 0.009 mg/L. None of the samples exceeded EPA target levels for copper.

The Town of Dillon distribution system and treatment facilities do not contain lead components. The water service lines to most building are made of copper, and soldered joints are not permitted outside the building. We have found that older plumbing with lead based solder (usually before 1988) and some faucets are typically the contributors to lead in finished water.


Our water comes from Laskey Gulch and Straight Creek. The water is filtered with state of the art membranes by Evoqua Water Technologies MEMCOR® Ultrafiltration Systems. After filtration, chlorine is added to protect public health and fluoride is added to aid in the prevention of cavities. To view the USGS Straight Creek Stream Gauge

Click for Information on the Old Dillon Reservoir enlargement project (ODR). The reservoir was drained amid safety concerns from the state engineer. Dying trees/roots on the north dam and a rusty overflow pipe were the major concerns. We will leave the reservoir dry to prepare for construction of the enlargement in the Spring of 2010 which is anticipated to continue until July 2012. We have partnered with the Town of Silverthorne and Summit County in the enlargement. This regional effort will help to provide a backup supply for Dillon and also will aid our partners in firming their available water.
