Cottonmill Floods 2011 - Situation at 15 jan 2012
The history of the flooding since November 2011 goes something like this. Flood prevention people from the Environment Agency in Sheffield inspected the site. The water table was (and probably still is) 12 feet below normal. An expert on ground water said that the flooding was not caused by ground water. Veolia (the water company) tested their mains pipe that runs through the site and there were no results - hmm. At a (probably third) meeting with the Veolia and council staff it was stated that the pressure in the mains pipe was tested and there was no leak. A 1 inch pipe was identified that was leaking. O'Connors (who are the contractors who do the council maintenance) stated that the loop that fills the water butts was not leaking; they switched the flow back on for 24 hours (it gets switched off in winter), and there was no percepible flow detected when looking at the water meter. So, back to Veolia. They said that the circuit they had switched off did not have a meter! No one seems to know what this circuit is. So... current situation (15 Jan) is that the council and Veolia are liaising to find out what this circuit is.
We should thank Alan Malin (our chairman) for liaising with the council and Veolia and meeting with them on numerous occasions on the site. Over and above the call of duty!
What it's all about:
Plots 67,68,69,70,71,72,73,74,75,76 77,78, 79 & 79A are all very badly affected by a lot of water. There are signs that the water is now appearing on plots42A 43A and 43 on the opposite side of the roadway and also on plot 39.
This is the text of an email sent on 30 November 2011 :
Alan Malin (CNAA chairman) has had
numerous meetings this week with representatives and hydrologists from
the Environment Agency and Veolia Water. It is now almost certain that
the large amount of flooding at Cottonmill is due to the 15"
mains water pipe running through the site which is seriously leaking.
Apparently, this water main cannot just be shut off and is 3 metres
below ground. Further tests are being carried out tomorrow to test the
water pressure to ascertain the extent of the leakage. The chaps from
Veolia say this is an urgent problem that needs to be resolved quickly.
Water, water everywhere
And not an albatross in sight!
Here's a pictorial flavour...
The floods only lasted a few days and no damage seems to have been done.
And a reminder of the 2008 floods:
The most recent 'find' is these photos of Cottonmill under water and ice from 2001.
And I've also just found some of my photographs of the floods in 1995 (or was it 1994?). The little lads are my sons (when they were sweet!).
And also John Boden's pictures of the 1994 floods which lasted for months.
