Re: {Tidal Potomac Fly Rodders} DC Wastewater Woes

I'm a TPFR member and an engineer on this project. This tunnel is the first to be constructed as part of the larger DC Clean Rivers Project. The long term plan includes a combination of gray (tunnels) and green infrastructure solutions to address the CSO problem in the city. Currently, DC Water is aiming to reduce some of the gray infrastructure by increasing the green infrastructure improvements in NW DC and in the rock creek watershed. You can read more about the overall program here: http://www.dcwater.com/cleanrivers and specifically the green infrastructure plan here: http://www.dcwater.com/education/green.cfm

As for long term maintenance and durability of the tunnel, a large screening shaft will be constructed at the termination of the tunnel at Blue Plains that will screen out all the debris that flows through the tunnel.  It will also be possible to clean the tunnels on a regular basis to ensure that they don't get silted up.

I'll grab a TPFR sticker next time I'm at a beer tie and slap her on the back end of Lady Bird. :)
