(Comment: We're taking a slight detour by reporting on this project, but the Ann Arbor WWTP is a significant project and most of the bidders are regulars on DWSD projects. The Project is scheduled to take 5 years to complete. Sharp-eyed observers will also note the photo used in the title block for DWSD Update is in fact a photo of the Ann Arbor WWTP. (Hat-tip: NS) I tried using several photos of DWSD's wastewater treatment plant, but all of them ended up obscuring the title text. So, I confess to taking a bit of editorial license. If you have a good photo from 9300 W. Jefferson, please send it along and I'll give it another try.)
