Common Water Issues in San Francisco

Solutions For Your Water Quality Problems

The majority of San Francisco's water supply comes directly from runoff from the Sierra Nevadas. The San Francisco Public Utilities Commission manages a complex water supply system that utilizes tunnels and pipelines to carry water from the area’s main reservoir to San Francisco. Using a system of pipes, tunnels, reservoirs, and canals spanning 167 miles, 220 million gallons of water is delivered to the Bay Area every day before being treated and disinfected at one of four main treatment facilities.

Hard, Poor-Quality Water

Due to the process of water filtration, minerals like iron and chlorine are added and absorbed, resulting in low-quality, hard water. Using hard water around the house may result in:

  • Hard-to-clean residue and buildup
  • Scratchy, stiff laundry and linens
  • Dry, itchy skin
  • Bitter, unappealing taste
  • Faded and dingy-looking clothing

Limescale Buildup

Limescale is a hard, chalky buildup caused by mineral deposits absorbed during the water treatment process. Results of lime or white scale buildup in the home include:

  • Sediment and scum buildup on kitchen and bathroom appliances
  • Difficult-to-clean surfaces
  • White scale rings around bathtubs and sinks
  • Increase in utility bills due to accumulated buildup in heating and cooling units
  • Buildup that clogs faucets and showerheads

Itchy, Dry Skin

One of hard water's most invasive traits is what it does to your skin and hair. Bathing or showering with hard water can cause:

  • Itchy scalp and dandruff
  • Limp, lifeless hair
  • Flakey, dry, irritated skin
  • Premature aging

Tips From the Culligan Water Expert

An easy and effective way of getting rid of limescale is by cleaning with a vinegar solution.
