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

Dissolved iron and other hard minerals are absorbed during the filtration and treatment process, as well as along water's journey from source to tap. These absorbed minerals and metals cause the water to become hard and its quality depleted. Some household headaches associated with using hard water include:

  • Clogged appliances that lead to water-flow issues
  • Hard-to-clean residue and buildup on appliances, hardware, and surfaces
  • Soap scum on showers, bathtubs, and sinks
  • Prematurely aged clothing and linens that are rough to the touch

Itchy, Dry Skin

One of hard water's most annoying qualities is the drying and irritating effect it has on skin. Some results of showering with hard water include:

  • Flaky, dry, irritated skin
  • Itchy scalp and dandruff
  • Premature aging due to dry skin

Lime or White Scale Buildup

Limescale is the hard, off-white deposit that creates buildup on many household items as a result of using hard water around the house. Some examples of this include:
  • Pesky sediment and scum buildup on bathroom and kitchen appliances
  • Underperforming appliances that result in added household costs
  • Off-white buildup that causes faucets and showerheads to clog
  • Difficult-to-clean surfaces
