  1. Hmmm,

    I believe that the Bremerton sewage treatment plant has been using treated wastewater to irrigate the area next to the Hwy 3 merge for many years. At least that is what I am assuming from the signs that say “non potable water”

  2. That’s a reasonable assumption, Gregg, but I was told that “purple pipe” was installed along the highway during development for use when reclaimed water becomes available at the Bremerton treatment plant. As of now, that plant does not treat its wastewater to a high enough quality.

  3. Since I worked in this field for a number of years, I do have a strong opinion on the topic. First there are a number of drugs, viruses and chemicals which are not removed in even tertiary treatment, secondly some of us don’t waste our energy or water on decorative lawns. Everything I grow is edible, I use drinking water hoses and want potable water flowing through them. We used to clearly state treated water and solids were to be used only where they would not come in contact with crops. That message got “forgotten” in the early 90’s with the move to save $$$ through reuse. It is still a valid concern.

  4. Gregg,

    I stand corrected. Pat Coxon manager of Bremerton’s Wastewater Utility tells me that the property along Highway 3 in front of Parr Ford is watered with Class B reclaimed water during the dry season. Because of its lower quality, the public can have no access to this property, which is fenced off.

    The water along Retsil Road, on the other hand, will be Class A reclaimed water, a higher quality that differs little from drinking water, according to state experts. No public-access restrictions are needed.

  5. We broached the idea of drinking treated water directly from a sewage treatment plant in this Aug. 17 blog entry.

    Now Dylan Walsh on the New York Times Green blog calls our attention to a new report that suggests highly treated sewage effluent from advanced municipal systems poses no greater health risks than those of many existing water supplies.
