Water Quality Partnerships
It takes more than a small city to plan and protect our water quality. Northglenn partners with Thornton and Westminster and other associations to ensure the highest water quality for a over 300,000 residents via shared storage at Standley Lake. This division's rigorous water quality monitoring program for the Clear Creek Watershed Foundation and the Big Dry Creek Watershed Association identifies pollutants and their potential impacts, while establishing guidelines for protecting our water source.
Water Quality Planning & ProtectionFederal and State legislation, rules and regulations define Northglenn’s source water protections, treatment processes, and discharge requirements. Through the participation with stakeholders, related associations, governmental and non-governmental agencies, Northglenn facilitates and implements policies involving current and future water quality regulations
Water Quality Special Projects – Wildfire Impact Study
In 2024, Northglenn begins its study on the potential impact of a grassland wildfire at or within proximity to Standley Lake and/or city limits. A grass fire at either location may affect raw water storage and pipeline delivery systems, the water treatment process including raw water storage at the Terminal Reservoir, drinking water storage tanks and distribution system.
The study will identify other raw water sources, mitigation efforts for water related infrastructure, outline alternate or augmented treatment methods to meet all state and federal drinking water regulations, and government permitting.

Frequently Asked Questions
Sometimes unpleasant odors can rise from the sink drain in your kitchen or bathroom. This is usually caused by bacterial growth.
Suggestions to minimize these drain odors:
- Put orange or lemon peels in your garbage disposal.
- Pour water with some bleach down the drain.
- Put baking soda in the drain, followed by a few cups of boiling water.
- Pour hot vinegar down the drain, followed by cold water.
- Repeat as needed.
Tiny air bubbles in the water cause the milky or cloudy appearance. If the water is left to stand for a short while, the bubbles will rise to the surface and disappear. If the white color does not clear, you could have mineral buildup in your hot water heater. Try flushing or cleaning your hot water heater. If white particles float, you probably have a deteriorating dip tube in your hot water heater.
Also, water heaters may rust with age, so if your water heater is old and you notice a rusty color when you run hot water, it could be time to clean or replace your water heater. If you take a hot water sample and compare it to a cold one, can you see a difference in color? If the answer is yes, the most probable source is the hot water heater.
Black color can sometimes be seen in tap water and usually occurs when faucet washers disintegrate with age. The most common way to correct this issues it to replace the washers and O-rings inside your faucet fixtures.
Tap water can sometimes appear "muddy" or "sandy.” Individual residents, but more commonly entire neighborhoods may be noticing the same problem. This can occur in your area when hydrants are flushed or when a water line is being repaired. To alleviate this issue, turn on all the taps in your home for 10 minutes to flush out the sandy appearance.
If fixtures are plugged, including toilets, with sand-like particles, the most probable source is an in-home water softener system. Zeolite, or resin beads, can escape from the water softener into the internal plumbing even if the softener is not in use. Proper maintenance should prevent this issue.
