Officials in Cary are going to keep a closer eye on water from now on.
The city says all new homes in neighborhoods that use treated wastewater for lawns will be sampled in the future.
The announcement comes after officials discovered this week that the reclaimed water was coming out of taps at two homes. While the water is suitable for watering lawns, residents are advised against drinking it.
Town Manager Bill Coleman says new houses will be checked specifically for the potential mix-up.
One man and his family found out they had been drinking treated wastewater when the irrigation system in his neighborhood was shut off. His neighbors had tap water.
After a house-to-house search in neighborhoods connected to the reclaimed water system, officials found one other house with switched connections. Officials are still trying to determine how the mix-up occurred.
