Paul - I've been on the sewer tour. It was very interesting, mostly containing rainwater runoff than poo. We emerged from a manhole on the edge of the Old Steine to the surprise of pedestrians. And you're right, it does raise questions on how much of underground could/should be mapped. I think i'd probably draw the line (no pun intended) at the entrances and exits to the sewer system.
Brian - Good pointers. Moving on to pumping stations next. I went out to find the Environment Agency borehole at Ladies Mile which turns out to be quite nondescript https://pbs.twimg.com/media/CzO5DodWIAAUbei.jpg:large it has its own telegraph pole as I believe they use a dial-up modem for communication. I also noticed a pub called The Reservoir whilst doing fhrs:ids. There is a temporary reservoir nearby hidden between two roads of houses. - Jez On Thu, 5 Jan 2017 at 12:12 Brian Prangle <[email protected]> wrote: > Hi everyone > > Don't forget there is also urban/industrial infrastructure relating to > water to be mapped: sewage treatment works, water treatment works, fire > hydrants (see my recent blog > <http://www.mappa-mercia.org/2016/12/a-guide-to-mapping-fire-hydrants-in-the-uk.html#comment-109666>) > and aqueducts/pipelines (especially the buried ones like the Elan Valley > Aqueduct which brings Birmingham's water from a reservoir in Wales). > There's a massive project underway to create a parallel route from the > River Severn for resilience purposes for the last part this > aqueduct/pipeline before it reaches Birmingham.
