NEW MEMBER OF PARLIAMENT MEETS FLOOD ACTION GROUPS

Adam Afriyie, the newly elected Member of Parliament for Windsor met with members from the flood action groups Community Support Group South and ThamesAwash on 12th May 2005. The aim of the meeting was to establish how Mr Afriyie could help residents who were so badly flooded in 2003.

Mr Afriyie was already aware that prior to the 2003 floods the Jubilee River had sustained damage which led to its operation being curtailed as the flood levels rose. As a result the scheme was not operated according to its design intent. This was to allow a large volume of water down the Jubilee River ahead of the River Thames natural flood peak. Over the past 27 months a huge amount of effort has been directed by both TAW and CSG South to extract and evaluate the flood data. The Mechanism Of Flooding Report stated that the operation of the Jubilee River only resulted in 2-3mm increase. It has now been shown that incorrect operation caused an increased water level of 300mm (almost 1ft) at confluence. Both CSG South and ThamesAwash disagree with some of the conclusions in the MOF Report although they do support its main recommendations.

It was explained to Mr Afriyie that the Jubilee River may never be able carry its design capacity. New and correct instructions relating to the Jubilee Rivers actual capacity need to be in place to ensure that mistakes made in utilisation of the flood relief scheme in 2003 cannot occur again. Furthermore Thames dredging for flood defence purposes ceased in 1995, while Thames side development has accelerated. The 2003 flooding has affected both property values and insurance costs, and any improvements resulting from the Lower Thames Study (which is currently considering flood alleviation proposals for the Datchet to Twickenham stretch of the Thames) could be 10-15 years away.

The group have asked that Mr Afriyie look into helping with regard to the following main issues:

1.Reinstate dredging immediately and get the River Thames back to the 1995 condition. Seek change of law to make dredging a duty for flood defence purposes.

2.Change of law to give EA more powers regarding planning applications in the floodplain.

3.Ask for an INDEPENDENT report by WS Atkins to review the reports which have been issued into the 2003 floods.

Mr Afriyie commented: 'Flooding is a key concern for the thousands affected. As the newly elected MP I will now be looking into concrete ways in which I can help in the near future.' He continued: 'My thanks to Community Support Group South and ThamesAwash for their well prepared briefing. I hope to be in position to take a firm stance in the weeks to come.

Transcript of 'You and Yours' Radio 4 programme - Thursday, 12th May 2005

Roger Waite: A new flood relief channel for the River Thames may have to be built to protect almost 30,000 people whose homes are at risk of flooding. They all live downstream of a flood defence project built three years ago - the Jubilee River, which cost 110M. It's emerged though that the design of the project was 'modified' in what is known as a value engineering project, in other words to save money on the original scheme, and people living in homes that were flooded in 2003 are convinced that this is one reason why another new set of flood defences is now being suggested. Well Melanie Abbot can tell us more. Tell us first Mel what the Jubilee River is?

Melanie Abbot: Well it's a man-made channel and is the Environment Agency's biggest ever inland flood defence project. It cost 110M. Although man-made, it was built to look as much like a natural river as possible and
was considered very innovative at the time. It's seven miles long and is designed so that water goes into the channel upstream of Maidenhead in Berkshire and returns to the Thames, downstream of Eton. The first time it
was used it protected 1,000 homes upstream but 500 homes downstream suffered the worst flooding since 1947.

Roger Waite: So these are the people presumably who think this value engineering exercise, as the euphemism goes, is linked to their flooding?

Melanie: Well, their confidence certainly hasn't been raised by these revelations about this cost cutting exercise, value engineering exercise, and of course the phrase hasn't gone down too well with them either. A
report written by the Contractors, Balfour Beattie, describes how they and the Environment Agency at the time had a 'get to know you' dinner followed by several 'getting to know you really well' drinks, and during this time they reviewed every aspect of the design and considered all changes, ranging from (the report says) the 'conventional' to the 'bizarre'. Ewan Larcombe is a Parish Councillor in Datchet, one of the areas which was flooded.

Ewan Larcombe: In 1999 the Client, that's the Environment Agency, the Designers, and the Construction Contractors, they all got together and used
this value engineering technique to change the design of the Jubilee River. Now I am exceedingly unhappy about that because in 1992, at the Public Inquiry, all these designs were on paper and they were submitted in evidence at the Public Inquiry. The Inspector's Report was written, here we have the Environment Agency and their Contractors, working together to change the
design. Now that was never put before the public and they have implemented design changes that I believe changed the performance of the construction.

Melanie: Now the contractors, they said that their value engineering exercise was designed not to change the quality of the design, not to change the content of the design, not to change the environmental impact of the design, but to do the same thing, but cheaper. Is there anything really wrong with that?

Ewan Larcombe: You have only to look at the very first time they put water through the Jubilee River in January 2003. Significant segments of the construction were damaged. Surely there is something wrong here? This is
110M world class award winning scheme that fell apart the first time that it was used.

Melanie: And Ewan Larcombe (speaking there) does think that there should still be a Public Inquiry into that flooding.

Roger Waite: And in the meantime we have these new proposals being put forward.

Melanie: That's right, there are five different approaches outlined to tackle the problem: (i) it does involve building new channels to divert the flow of the River Thames away from those areas liable to flooding. This could cost up to 200M, it would take 10-15 years to complete and would need to be approved directly by the Treasury. Another suggestion is what is known as 'river bed re-profiling'. Attempting to make the river deeper and perhaps wider. There are less ambitious options such as temporary barriers and an enhanced flood warning system. Now these suggestions - the
Environment Agency says in its announcement - are a direct response to extensive flooding in January 2003 which affected those 500 homes.

Roger Waite: And what has been the reaction to those ideas?

Melanie: Well, 'luke warm' I think would be the word. Gillie Bolton, who lives on Ham Island in Old Windsor, she spent days only being able to get to her house by canoe back in 2003. She now sits on the pressure group 'ThamesAwash' which was set up to tackle the flood risks.

Gillie Bolton: We are delighted that they are looking at these proposals, but so much more work has got to be done, because they are talking about new channels, and in my opinion, until they have the Jubilee River working
properly and effectively, how can they consider building new channels. They are talking about river bed re-profiling and again, I believe that this comes in with the dredging, but perhaps to a wider issue.

Roger Waite: Gillie Bolton, but is there real clear evidence now to link the Jubilee River with the flooding of people's homes?

Gillie: There have been independent studies carried out to show that the Jubilee River didn't contribute to those floods, but there has also been a study by independent engineers called Atkins, which pointed to a long list
of design problems with the channel, as we reported on 'You and Yours' last year. These include things like a convex weir, which arches the opposite way from what you would normally expect, no mechanism to slow down the flow of water, and the report also said that the channel was operating at only 80% of the intended capacity, and this is interesting, because it was
something predicted at the original Planning Inquiry back in 1992, by Peter Ackers, a Civil Engineer, who has now retired, but who assessed the plans at the time, and he wrote then "that it would be very embarrassing for all
concerned if the intended capacity wasn't achieved, saying that it's not an issue that could be clouded over and any deficiency would bring widespread and justified criticism", and I asked him what prompted this conclusion.

Peter Ackers: It was the largest drainage scheme that had ever been built and it had many novel features, it was in a very sensitive area, and it was fairly obvious that if it failed to achieve its objectives, then there would be plenty of people there to complain.

Melanie: And what in particular about the scheme made it different from other schemes which concerns you, and perhaps led you to believe that it may be quite difficult to predict the capacity of the channel?

Peter Ackers: The fact that it was following the latest good practice of very natural looking channels, fitting much better into the landscape, but from the high prerogative point of view, that made it very difficult to
predict just what its flow capacity would be.

Melanie: Peter Ackers. And he also told me that at the time, no research had been done into the capacity of natural flood relief channels designed in this way.

Roger Waite: And what does the Environment Agency have to say about all of this?

Melanie: Well I spoke to Ian Tomes, the Area Flood Defence Manager, and asked him first what he thought about Peter Ackers' perhaps rather far sighted comments.

Ian Tomes: What I would say is that at the time, the best available information was used to design the scheme. You have to remember that the hydraulic or the computer model that was used, was right back in the 1990's, this was scrutinised by the Public Inquiry by hydraulic consultants, and was found to be perfectly OK. What's happened is that we have the flooding of
2003 which has given us a lot of new information about the Thames' flows and levels, and if we designed the scheme now with that new information, it may be different.

Melanie: To people living downstream then from the Jubilee River that might sound almost as if they were being used somewhat as guinea pigs for this scheme?

Ian Tomes: Not at all, as I have said already the best available information that was available was used at the tome. It was scrutinised at the Public Inquiry by independent experts and they didn't have a problem
with it.

Melanie: Why is there now then a need for this new strategy to those people living downstream of the Jubilee River, they have been saying that it does
look like an admission of failure of the scheme?

Ian Tomes: No not at all, one of the highest areas of flood risk in the country with nearly 12,000 properties at risk in a 1:100 year flood event, is the area downstream of the Jubilee River, between Datchet and Teddington,
and that risk has always existed.

Melanie: What about this 'value engineering' exercise with something as controversial as the Jubilee River - how wise is it to shave off the costs by changing the design or altering the materials used.

Ian Tomes: I think the first thing I would say about that is that value engineering is not about driving down the cost, it's an error to think that it is. It's actually a standard industry approach really which has been
used for many years on large construction projects, it's about optimising the mix of cost, performance and fitness for purpose. The other thing I would say is of course that at a Public Inquiry, the detailed design is
never done before a Public Inquiry.

Melanie: But if it's not about driving down costs then why would the contractor (Balfour Beattie) write this report really trumpeting how well they had managed to limit the cost of the project.

Ian Tomes: Well I mean, yes, the cost is one element but its optimising that mix of both cost, performance and fitness for purpose, so reducing the cost may be one outcome, but also getting better performance and better
fitness for purpose may be another outcome as well

Melanie: Ian Tomes from the Environment Agency speaking to me then.

Roger Waite: Thank you for speaking to us Melanie Abbot.

End of discussion.

Dear Sir,

I read (Maidenhead Advertiser-29/7/2005) that Thames Water was fined 132,500 last year for pollution incidents. Apparently the Environment Agency (EA) led the cases, and the EA Regional Director is quoted as saying . but it does demonstrate how committed we are to combating environmental crime.

It appears to me that the hypocrites in their ivory towers at the EA continue to practice double-standards by conveniently ignoring algae growth in the Jubilee River.

At the Public Inquiry in 1992, I was assured by the experts that the MWEFAS (now called the Jubilee River) would be more like a river than a swamp.

For the third year in succession the Jubilee River is covered in places from bank to bank with vast areas of green algae that extend over 100m upstream. This algae accumulation is a safety hazard that is both predictable and avoidable. The EA solution last year was to allow the mass of material to be flushed into the Thames, which I find deplorable.

This is undoubtedly an EA problem, but I dont suppose they will be prosecuting themselves for a pollution incident, which then leaves me with the question who polices the policeman?

Yours sincerely

Ewan Larcombe

Dear Sir

Apparently the Environment Agency (EA) intends to close two footpaths on the Jubilee River (JR) in order to make repairs at Slough Weir. Their 'Notice of works' refers to 'prolonged rainfall in 2003 that created high flows and caused damage to the weir and severe erosion of the banks'.

In fact any high flows that damaged the Jubilee River in January 2003 were entirely as a result of EA personnel operating the inlet flow control structure at Taplow, and even then at a flow rate significantly within the design capacity of the JR.

After these repairs to the Slough Weir and embankments are complete, this 110m world class award winning scheme will still be unable to safely carry its design capacity of 215 cumecs due to its significant design and
construction deficiencies.

There is now evidence that the mathematical hydraulic model performance was exaggerated at the 1992 Public Inquiry. The design was then changed after construction contracts were placed in order to reduce costs.

So who is paying for these repairs? I am unhappy that having already spent about 1.3m (of your money and mine) rebuilding 300m of substandard embankment in Datchet, the EA continue to spend on a flawed and substandard flood defence scheme. Indeed it is arguable that EA policy has now 'moved on' from building and maintaining flood defences to one of 'flood risk management'.

For the third year in succession, the JR has suffered from the predictable and avoidable problem of algae. Both Slough Weir and Black Potts Weir are already heavily contaminated, in spite of assurances from the 'experts' at the 1992 Public Inquiry that algae would not be a problem. The EA are now apparently intending to reduce the water level downstream of Slough Weir by
0.9m, the effects of which should be interesting to observe!

Yours faithfully

Dear Sir

A new publication from the Royal Academy of Engineering (RAE) adds weight to my assertion that any public lack of confidence in the Environment Agency (EA) is entirely justified. It is almost three years since hundreds of households downstream of Windsor suffered from flooding for first time since 1947 and the EA have spent that time vociferously denying that their newly constructed 100m Jubilee River and failure to maintain the Thames exacerbated the flooding. I have previously revealed that no sooner were the MWEFAS construction contracts placed than the EA were involved with the designers and contractors in a value engineering exercise.

The RAE (Professors Dodds and Venables) have now referred to the Jubilee River in their Engineering for Sustainable Development: Guiding Principles published in September. Principle 11 (of 12) states Beware cost cutting that masquerades as value engineering and makes reference to the Jubilee River by saying The wider implications of design changes made during construction may not always be easy to spot.
I am unhappy because not only is the EA (funded by us) apparently responsible for sub standard design and construction, but they continue to avoid accountability. Furthermore I believe that when a planning application is approved by a Minister after being scrutinized at a Public Inquiry, surely any significant changes should be the subject of a further application and appropriate consultation.

Sir

Now that Michael Howard MP has relinquished his position as Leader of the Conservative Party I can reveal that he was Secretary of State for the Environment when the Inspectors Report on the 1992 MWEFAS Public Inquiry was presented to the Government in April 1993. (John Gummer MP was Minister for Agriculture, Fisheries and Food at the same time.)

Mr Howard should now have more time available, so maybe he could consider looking into how a proposal that traversed his desk over twelve years ago and was then built by the Environment Agency (EA) went so wrong. Funded through the Thames Region Flood Defence Committee at a cost to the public purse of 110m and now called the Jubilee River, the scheme fell apart on first use. Currently unable to carry its design capacity due to design and construction shortcomings and with repairs ongoing into 2006, the EA are now
apparently planning to survey the Jubilee River channel bed. Need I say any more?

Yours faithfully

Ewan Larcombe
