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.

• 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.

• Harrow Area Flooding

We wrote to Rachael Shimmin the Bucks Council CEO requesting an investigation into the causes of the flooding, and have received two replies from Rosie Tunnard. The first essentially describes the flooding as a well maintained drainage system simply being overwhelmed by sheer volume of rain and detritus swept along the road.

The second carries some notes from the Flood Management Team, who are putting some work into analysing how the problems occurred.

We are currently looking into the contents of these letters and intend to reply soon. However, there are some possible good points in the letters:

• Clearance of gully systems have been ordered
• Looking into possible solutions to better direct road water into the Warrendene ditch
• Hampden Rd ditch is to be cleared (looking very overgrown)

• Thames Water

Despite expectations to the contrary, TW started overpumping by the Surgery this month. This has provided much relief to those neighbours who were experiencing sewage spillages in their gardens.

We are currently organising a daytime meeting with Mark Dolby, a Snr TW engineer to visit and update us on current activities.

The sewer remains full and becomes threatening when we have heavy rain or when the  overpumping unit stops running for any reason.

A look at the Hughenden Borehole graph shows that the groundwater levels are slowly going down, but have a long way to go before the stream stops running.

• Chiltern Society

Paul was invited to a Chiltern Society Friends event, where representatives of the groups that look after the Chiltern chalkstreams gathered. This was a new event to try and bring each of the groups closer and encourage joint production of plans etc.

Paul will pick up with the Revive the Wye group who look after the Wye but also have the Hughenden Stream as part of their remit.

Paul also to identify any persons or group in our valley wanting to take on a role in this.
