Quistorff’s Henderson Bay Treatment Plant

Iron and manganese removal treatment has been installed for the well source. The treatment facility will remove naturally occurring manganese from the source water, which slightly exceeds the secondary drinking water standard of 0.05 mg/L, at 0.08mg/L. Treatment will also continue to remove the naturally occurring hydrogen sulfide odor (rotten eggs). Nearby customers may be impacted in the following ways:

1. You may notice periodic increase in chlorine taste. The treatment removal process requires an increase in the level of chlorine injection compared to the level you experienced before treatment was operational.
2. The new treatment may cause discolored water for a short period of time. If you experience discolored water, open your outside hose bib (faucet) and flush until clear.

Washington Water operators will be routinely flushing the distribution network to purge the discolored water from the network before it gets to your house. This is a short term nuisance that will dissipate over time as the new water chemistry in the distribution stabilizes.

Additional improvements will continue to take place at the treatment site over the coming weeks to close out the project. In the meantime, please avoid the area as hazards may exist in and around an active construction site. We thank you for your patience in advance and apologize for any inconvenience during this project.
