Drainage work starts again

I learned that work to complete the drainage channel had finally re-started so I have taken a few pictures of this area.  A small work compound has been established by the viaduct and the sheeting has been removed.

In this first picture a three car service has just moved onto the viaduct.  Water from the viaduct will fill this pond and any contamination will settle out.  Only when the level reaches the outflow link bottom right will any water move through to the river.

A closer look reveals the outflow from the viaduct drainage system.  The sheeting that has been removed is rolled up and stored on the left.

At the other end of the settlement pond, the link to the final outflow on the River Hiz has been installed.

And this is the outfall into the River Hiz which can be seen top right.

Same location showing both ends.  Riverside footpath has become really overgrown again. Fenced section the only clear part!

Not quite sure what this trench to the side is for yet.  I guess it will become apparent in due course.

This is what it looked like before the current work started.

Nature is reclaiming the cleared embankment quite quickly.  This was bare a year ago.  Two trees cut down above the bridge are re-establishing themselves.

Here are three pictures I took from the Icknield Way footbridge in March.  First shows a FCC service crossing the viaduct as it passes over the ECML.

             Now moving onto the section that passes through the redundant sewage treatment site

               Finally zooming in, you can see it it joining the Cambridge line at Hitchin East junction.  

For anyone interested, I have started a new blog covering the East West line work including Chiltern   Railways Evergreen Three Project.  This will be a longer term project as the timescales have already slipped since I started it.  I will try to do a monthly update whenever possible.
