Public Notice: Temporary Water Discoloration
BUTNER, NC - South Granville Water and Sewer Authority is informing customers of temporary water discoloration that may be affecting portions of its service area due to elevated levels of manganese, a naturally occurring mineral.
SGWASA's drinking water continues to meet applicable state and federal drinking water requirements and remains safe for normal household use, including drinking and cooking.
What Is Causing the Discoloration
Prolonged dry conditions since April have reduced natural lake recharge, contributing to increased mineral concentrations in the raw water supply. Additionally, seasonal lake turnover, which occurs as cooler temperatures cause surface and deeper lake waters to mix, can introduce naturally occurring manganese into the water.
What SGWASA Is Doing
SGWASA is actively monitoring water quality, adjusting treatment processes, optimizing manganese removal, and conducting targeted water main flushing to address affected areas and improve water clarity.
Customers experiencing discoloration are encouraged to:
Check water before laundry: Avoid washing light-colored clothing when discoloration is present to prevent staining.
Flush cold water: Run an outdoor spigot or lowest-level cold water faucet for 3–5 minutes. If discoloration persists, contact SGWASA.
Limit hot water use: Avoid introducing discolored water into household water heaters.
SGWASA appreciates customers' patience and understanding as treatment and distribution system adjustments continue.
Do you have questions or are you experiencing persistent discoloration? Contact SGWASA Customer Service at (919) 575-3367 or visit sgwasa.org/wq for additional information.
