Where the water comes from
Big Creek Utility District's main water source is surface water (rivers, lakes or reservoirs). It buys treated water from Griffith Creek U.D., Cagle-Fredonia U.D.. The seller treats the water, including corrosion control that keeps lead from dissolving out of pipes, while Big Creek Utility District is responsible for its own service line inventory and replacement program. It sells water to 2 other water systems: Griffith Creek U.D., Cagle-Fredonia U.D..

Protect your drinking water now
If your line is lead, galvanized or unknown, filter water for drinking, cooking and baby formula. Use a filter certified to NSF/ANSI 53 for lead. Run cold water for a few minutes after it sits for hours, and never use hot tap water for cooking.
