Larkspur Water Quality: What You're Dealing With
Larkspur and Douglas County water is known for high hardness — typically 16–25 grains per gallon. Water source: Larkspur Water District for town properties; Denver Basin private wells for rural parcels throughout northern Douglas County.
Larkspur Water District serves a limited area of the community. Municipal water here contains high hardness and moderate chlorine levels. Homeowners commonly see scale buildup on appliances and fixtures, corrected effectively with a metered water softener paired with a carbon pre-filter.
Many Larkspur and northern Douglas County properties are on private well water. Denver Basin wells in this area commonly carry iron (1–5 ppm), high hardness, and occasionally hydrogen sulfide. A site-specific water test guides the most cost-effective treatment plan.
Common Larkspur Water Problems
- High hardness (16–25 gpg) in both city and well water
- Iron and sediment from older distribution infrastructure
- Hydrogen sulfide odor in some well water sources
- Scale on water heaters, faucets, and shower enclosures
- Elevated TDS and manganese in private wells
- Limited municipal supply causing reliance on well water
