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

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.
