The Pinery Water Hardness & Quality Report (2026)

The Pinery Water & Wastewater District provides water to about 12,901 residents in Parker, Colorado. Their supply comes from surface water purchased from other regional providers. All treatment and distribution operations are handled at their facility located at 5242 Old Schoolhouse Road in Parker, CO 80134. This district operates under Public Water System ID CO0118025 and is overseen by the Colorado Department of Public Health and Environment. The Pinery service area is situated within the South Platte River watershed, a significant drainage system in the Colorado Front Range.

The ground beneath Pinery is composed of Cretaceous-age sedimentary rocks, specifically the Pierre Shale and the Niobrara Formation. These are covered by Tertiary alluvial deposits and loose gravels. When water, both surface and ground, travels through these mineral-rich geological layers, it picks up dissolved calcium and magnesium. This process results in a moderately mineralized water supply, which is quite typical for the Denver Basin area.

With its moderately hard classification, Pinery's water will eventually lead to noticeable scale buildup in appliances like kettles, coffee makers, and dishwashers. You might also find that soap isn't quite as effective for laundry and bathing. While the hardness isn't severe enough to require mandatory treatment, many homeowners opt for water softeners, either whole-house systems or smaller point-of-use units, to help appliances last longer and improve cleaning results. Regularly descaling your appliances is a good idea, and you may need to use slightly more soap than you would with softened water. The district's 2025 Drinking Water Quality Report shows waivers for several tests, including cyanide and asbestos, but also notes 7 contaminants above EPA health guidelines and 1 MCL violation.
