[Talk-GB] Brighton water (quarterly project)

[Brian Prangle]

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. Mapping that will take a
lot of effort (STW won't release any opendata maps claiming protection of
national critical infrastructure - the sorry saga of which will form a
future blog). It might be a satisfying project to dig out the Victorian and
Edwardian archives in libraries and map the aqueducts/pipelines connecting
cities to their respective reservoirs in the mountains.

Mapping fire hydrants is a nice little treasure hunt, which gives you an
opportunity to revisit streets/roads that haven't been visited for a long
time

Regards
