Denver Direct: What is in the Effing Effluent?

What is in the Effing Effluent?

We’ve been blogging about squirrels with bubonic plague, ducks dying of botulism, lake bottoms being replaced, and the Effing Effluent (tm) a.k.a. recycled water, sewage effluent or greywater, i.e. the stuff which is being sprayed on the fields and filling up the lakes. But what is actually in it?

I was finally able to obtain a copy of the original (thanks to the indefatigable Adrienne Anderson,) Industrial Wastewater Discharge Permit No. 1-118 granted by the Metro Wastewater Reclamation District to the City and County of Denver and Waste Management, Inc. to “discharge treated groundwater and incidental operational wastestreams through the outfall(s) identified herein to the sanitary sewer system, in accordance with the effluent limitations, monitoring requirement and other conditions set forth herein.” In other words, what they can flush into the sewer system, and thence on to the “recycling” plant.

Notes:

1. Aurora is included in this system, and I am leaving it out to simplify the overview.

2. All of this is from the original agreement. I have not yet been able to obtain a copy of the current agreement, but I understand that the limitations have been increased.

3.The list below is just the ingredients that are monitored and regulated. There may be other contaminants.

4. Below the list are copies of the actual document, where the detail-oriented can find the actual numerical limits.
