Welcome to OWASA

Capital improvement project at University Lake

Did you know that University Lake is the community's original raw water supply formed in 1932? It was originally piped to a filtration plant at UNC, and today it is treated at OWASA’s Water Treatment Plant. The construction of the dam at the lake included flashboards to enable increased water storage. OWASA has begun replacing the flashboards to ensure continued reliable water storage for the community. Learn more about this capital improvement investment into the community's water system here.

2018: record setting year for rainfall!

OWASA has 128 years of rainfall data for the local area. In 2018, we recorded our highest year of rainfall on record in Carrboro at 74.7 inches. That's about 27 inches above the 128-year average of 47 inches per year! Curious about how much water is available and how much the community uses? Learn more here!
