Ensuring quality tap water is a shared responsibility of Chatham County Water and individual residents. When water flows from the treatment plant to your tap, many factors in the distribution system and household plumbing can affect your water quality.

Tips to Ensure Household Water Quality 

Flush cold taps when household water is not used for several hours

  • Run cold water taps for two minutes before using water for drinking and cooking. When water sits in your pipes for long periods of time, water quality can decline.
  • To conserve water, other household water usage activities are effective methods for flushing pipes and allowing water from the distribution system to enter household pipes. This includes laundry, showering, flushing the toilet and running the dishwasher.
Do not use hot tap water for drinking and cooking
  • Hot water dissolves contaminants and may contain metals, sediment and bacteria that build up in the water heater.
  • If you have household lead sources, hot water can cause lead to release in your drinking water.
Routinely replace filter cartridges
  • Bacteria and metals can build up in filter cartridges. Be sure to follow the manufacturer's instructions for filter replacement.
Replace old household plumbing and potential lead sources
  • Replace galvanized plumbing with copper pipes and install "lead-free" plumbing fixtures that contain 0.25 percent lead or less.
  • After installation, flush cold water taps for five minutes once a day for three days.
Routinely clean faucet strainers
  • Sediment and metals can collect in the aerator screen located at the tip of your faucets.
  • Replace aerators that are in poor condition. These are available at local hardware stores.
Drain your water heater annually
  • Sediment, bacteria and metals can build up in the water heater tank. This can impact household water quality and water pressure.

Flush cold water taps after installing new household pipes or fixtures.
  • New plumbing can release metals after installation.
  • Flush plumbing for five minutes at a high flow rate once a day for at least three days.
