Westminster Water Softeners & Water Treatment

About Westminster Water

Westminster is primarily served by Denver Water, drawing from the treated South Platte River supply. Westminster's proximity to Denver's Moffat Treatment Plant — one of the primary treatment facilities — means the water has less transit time in the distribution system, contributing to its slightly lower hardness compared to more distant suburbs.

At 7.4 GPG, Westminster's water is borderline between moderate and hard classifications. Calcium and magnesium levels are lower than in south and east metro areas, but are still high enough to cause scale on fixtures over time and reduce the efficiency of water heaters.

Westminster homeowners moving from Boulder (4.2 GPG) will immediately notice the harder water. Those coming from Parker or Castle Rock will find Westminster's water noticeably softer by comparison.

Recommended Treatment for Westminster

A standard 24,000–32,000 grain salt-based water softener is suitable for most Westminster households. The lower hardness means smaller capacity systems are adequate, which reduces both equipment cost and salt consumption compared to south metro cities.

Westminster homeowners who prefer a no-maintenance option may find that a salt-free template-assisted crystallization conditioner provides adequate scale prevention at 7.4 GPG, particularly in smaller households.

For drinking water quality, Denver Water's chloramine treatment can affect taste. An under-sink activated carbon filter or reverse osmosis system addresses this effectively and is commonly paired with whole-house softening in Westminster.
