• Harrow Area Flooding

Following our follow up letter to Bucks Council on the February flooding, we received a response from the Council dated 5^th September from a Community Liaison Officer assuring us that they are confident that the drainage system in place is adequate and with proper maintenance the flooding will not happen again. Our request for a meeting has been ignored.

Since then, of course, the Harrow and multiple gardens were flooded on 23 September. It’s terrible that another flooding has occurred in the Harrow area following a very heavy period of rain over the weekend. From what understand the response from the Council and Fire Services has not been great

• Presentation to Flooding Response Select Committee

We provided a paper to the Select Committee for their meeting on Monday 23^rd September. The meeting was changed from the Aylesbury office to an online meeting because of flooding in the area.

• Chiltern Society & the Hughenden Stream

Paulw and Sarah Mustapha attended the 2nd Chalk Stream Project workshop on 15^th July about the Hughenden Stream Restoration Plan. This second meeting was to prioritise the works so that decisions can be made on what can or cannot be done, allowing for budget etc.

By December it is hoped that a document will be produced for public dissemination.

We were introduced to Robert Morsley, a consultant hydrologist from the River Thames Conservancy Trust. Robert has been assigned to the stream restoration project to investigate Natural Flood Management possibilities for the upper reaches of the stream, namely from the pumping station up to the top of Warrendene and beyond.

Hi All,

               It’s terrible that another flooding has occurred in the Harrow area following a very heavy period of rain over the weekend. From what we hear at this end of the Valley, the response from the Council and Fire Services has not been great.

On this subject I am enclosing a couple of letters in connection with our pursuing Bucks Council to take action regarding the repeated flooding. The first is our letter to the council of 5^th August which was following up again on the February flooding. The second letter is response from the Council dated 5^th September from yet another Community Liaison Officer assuring us that they are confident that the drainage system in place is adequate and with proper maintenance the flooding will not happen again. I will leave you to draw your own conclusions on that.

Yesterday Bucks Council held a Select Committee meeting on the response to flooding in Bucks. The DIG, along with other groups were invited to attend. In the event, I put in a paper expressing our views on the difficulties we have experienced over the years with flooding. I have attached this also.

On a slightly brighter note, yesterday there was a follow-up meeting at the Manor on the Restoration of the Hughenden Stream and Sarah Mustapha and I attended this. This workshop looked at prioritising the areas of work on the stream from a feasibility and benefit point of view. From this work it is expected that a draft plan will be produced and made available for public dissemination.

At the same time we were presented to by Andrew Morsley from the Thame Conservation Trust. The TCT has been appointed to survey and recommend Natural Flood Management measures affecting the Valley. This forms the next part of the Chalk Stream Project and looks at the upper reaches of the Hughenden stream and valley, roughly from the pumping station up to the top of Warrendene and then also flooding from beyond that point. It is hoped that in the fullness of time measures will be introduced to better manage surface water finding its way down into the valley.

Some of you affected by the flooding will have already met Andrew, as he stopped in the Harrow area yesterday before the Chalk Stream meeting to see for himself our issues over the flooding and spoke with a few of you. He may well be a familiar figure around Warrendene in the coming months.

Regards

• Harrow Area Flooding

We have written to Rosie Tunnard in early August. This letter refuted the Council’s response that the Harrow/Warrendene area is properly maintained but was simply overwhelmed by exceptional rain that day in February.

We have requested a meeting to discuss works we consider necessary to improve the area’s drainage.

• Presentation to Flooding Response Select Committee

The DIG has been invited to present to the Bucks Council Select Committee on Flooding Response. Paulw will present on 23^rd September the result of our experiences with local flooding events and the council’s response to it.

• Thames Water

Overpumping at the Surgery now is largely forgotten; all  equipment is removed and a cleanup has been done. The field below the pumping station still looks a mess.

We are still pushing Thames Water for a solution to the Valley’s sewage network issues. Some hope that!

• Chiltern Society & the Hughenden Stream

Paulw and Sarah Mustapha attended the Chalk Stream Project workshop on 15^th July on the subject of the Hughenden Stream Restoration Plan. This was held at Hughenden Manor. It involves re-working the Hughenden Stream from down in High Wycombe up as far as the pumping station. It is being driven by the Chiltern Society and Environment Agency and is fully funded, so will be a significant project.

On 23^rd September there is a follow up workshop when a proposed list of alterations along the stream length will be agreed. At a future point a document containing proposed restoration options will be produced for public dissemination.

At some point the upper reaches of our stream (Pumping station to Warrendene Crossroads) will be surveyed also.

It is also understood that the Chalk Stream Project has been invited to work with Bucks Council on Natural Flood Management in Hughenden Valley.

Hi All,

               Please find enclosed a short update on DIG activities.

• Harrow Area Flooding

We have not yet followed up with our reply to Bucks Council regarding the Harrow area floods. We need to do some more checks before writing to the Council and suggesting a plan for drainage improvement in the whole Warrendene and Harrow area.

• Thames Water

Pumping out at the Surgery has continued through June, although TW have reduced the revs on the overpumping equipment because of lowered sewer levels. A casual inspection at the month end suggests that the sewer levels are now very low and we expect the overpumping operation will likely stop soon.

The tankering from Boss Lane has now stopped and TW are looking to repair verges etc.

• Chiltern Society & the Hughenden Stream

Paul met with James Donald of Revive the Wye group 17^th June for Paul to be able to provide an introduction to the DIG and the upper reaches of the Hughenden Stream (from the park up to the top of Warrendene Rd). Paul will organise a meet up with James Donald late July to provide a walk of the upper reaches.

Since the meeting with James Donald, the DIG has received an invitation to attend a Chalkstream Project workshop on 15^th July on the subject of the Hughenden Stream Restoration Plan.

I attended a meeting with the Climate Group who have shown interest in this workshop and up to 4 of us will attend the workshop.

Hi All,

               Just sharing a response from Maisie Banks regarding the overpumping units. We had felt that the pumps should be retained for a while longer because of the recent heavy rain, but obviously TW don’t think it necessary.

Hi Paul,

Hope you are okay,

I have spoken to Lynda who has been monitoring the levels in within our sewer network, as the levels have dropped we turned the over pump off on Thursday 4^th July and since then we can see that the network has been coping with the flows.

Since the over pump has been off we’ve experienced rain fall within the area and have noticed that the ground water levels have also dropped. As we are happy that the network is coping and the additional flows that were getting in have reduced we will be arranging for the over pump to be removed as it’s no longer needed.

Please advise the residents that if they have any issue to call our contact centre on 0800 316 9800 or report an issue online so we can send out an engineer in a timely manner to investigate.

Kind Regards

• Harrow Area Flooding

We are slowly progressing towards assembling a response to Bucks Council regarding the Harrow area flooding. Paulw has conducted a visual check on the area up to the top of Warrendene Rd and Matt Hopkins is part way through checking drainage at Hatches, Bryants Bottom Rd and Hampden Rd.

We hope to be able to write to Bucks Council by the end of June.

• Thames Water

Pumping out at the Surgery has continued through this month and tankering from Boss Ln. The latter is becoming increasingly unpopular with the residents of Boss Ln because of noise and access problems.

The DIG met with a small team from TW this month. Results from meeting:

• We now have a permanent contact for the DIG in Maisie Banks, Custoner Liaison engineer.
• Mark Dolby (Snr engineer) is in the process of putting forward suggestions for hydro-braking for Hughenden Valley. This has to be data modelled for the whole valley and will include the Naphill & HV sewer junction problem. No timescale available on this.
• TW looking at reducing the frequency of overtankering with the weather improvements
• There will be a cleanup done in Boss Ln and the field below the pumping station when tankering /field leakages finished.

• Chiltern Society

Paul meeting with James Donald of Revive the Wye group 17^th June.
