Minor issue at Meadows water treatment plant may impact smell for some water customers

For a limited time, a glitch at the water treatment plant in the neighborhood caused the system to overfeed chlorine while treating water Wednesday. Ensuring customers have safe, quality drinking water is the No. 1 priority for Castle Rock Water. This morning, the department wants customers to know, your drinking water is safe.


The defect happened at about 9 p.m. Wednesday at the water treatment plant in The Meadows. The plant had been shut down for the season. However, crews were restarting the plant to accommodate water supply needs during maintenance at the Plum Creek Water Treatment Facility.


For about 15 minutes, the automatic measuring system overfed chlorine while treating the water. Crews testing The Meadows plant’s water quality identified the malfunction. The system was then flushed last night to remove the water with excess chlorine.

This is similar to a pool that has been treated with a higher than normal chlorine level. Crews are in the neighborhood flushing the system for a second time this morning.


This was an isolated incident and does not pose a danger to the public. Castle Rock Water is now evaluating procedures to make sure this minor issue with this treatment plant does not reoccur.
