Sewage Issues

There is a back sewer that runs through the Hopkins Farm field that faces onto Valley Road. The sewer then runs along the back of the row of the white cottages through to Boss Ln where there is a junction with the Boss Ln sewer. This sewer had been causing spillages in the farm field and in late January started spilling into the garden of Woodland Cottage on Valley Road.

After many visits by Thames Water, including removal of a partial blockage, a tankering operation and CCTV work, we think this problem is now sorted, although we have not received confirmation of this from TW.

Floods Meeting

We are expecting a community meeting to be finalised for late this month to address the flooding issues in the Warrendene area and Bryants Bottom. This meeting is not a direct replacement for the cancelled meeting with Jilly Jordan but is with Andrew Morsley of the River Thame Conservation Trust, who has been spearheading the Natural Flood Management analysis in our area. There will also likely be representatives from Bucks Council we understand.

We will be putting leaflets through the doors of houses in Warrendene Road as far as Perks, from the Harrow along Valley Rd to the Hopkins field, also in Bryants Bottom. The meeting will be of particular interest to those affected by the flooding but is a public one and other interested residents are very welcome.

Program of Work in Warrendene & Bryants

Work on the Warrendene Rd ditch and drainage network was expected to start the week commencing 23 February but did not. We are presently pursuing this but may be 11-12 March.

Warrendene Road Drainage Works

This is scheduled to take place next week starting 23^rd February. My understanding is that the initial focus is on clearance and deepening of the ditch, but they should additionally be jetting the drains as well. I am also hopeful that several reported drainage problems will be resolved at this point. At a later point the road drains will be removed and replaced with larger models.

It will be helpful if you can keep an eye open for any work relating to your own particular issue. I will be visiting several times to see what is happening and will try to check in with James Tunnard during the period of the work.

Sewage Issues near the Village hall

I am glad to say that the garden flooding experienced at Woodland Cottage in Valley Road has been resolved for the present – a partial blockage was found in the back sewer down near its junction with the Boss Lane sewer.

However, Matt Hopkins reports that the levels in that sewer remain high and that TW have indicated that the sewer is overloaded from the park through to High Wycombe. TW are believed to be working to alleviate this.

As a result of this the network is backing up towards Hughenden Valley. Hopefully, this is not a sign of problems to come for us near the village hall. I have checked my inspection pit this morning – it is perhaps 10% full, it was empty this time last week.

               This update only affects residents in the lower end of Hughenden Valley in the village hall aea.

You may have noticed TW and Lanes Drains vehicles have been putting in an appearance quite frequently over the past few weeks.

There is a back sewer that runs through Matt Hopkins’ field that faces onto Valley Road. The sewer then runs along the back of the row of the white cottages through to Boss Ln where there is a junction with the Boss Ln sewer and the one that runs along the back of the houses from Herrison House. The Boss Ln sewer then joins the main sewer in Valley Rd.

Matt had experienced a sewage leak in his field from one of his inspection pits before Christmas and again in January. It has taken several visits to resolve this – a blockage of some sort. Subsequently, one of the white cottages on Valley Rd has been suffering considerable discharge of sewage over a prolonged period in the last few weeks. The garden is seriously flooded but repeated visits by TW have not resolved this problem. Their efforts have essentially diagnosed a ‘Hydraulic Overload’ (too much water) whereas we consider this to be a blockage of some sort.

It is clear that this back sewer is mostly full and what’s more is that this fullness appears to run up to the main sewer and then along to the bus stop opposite the village hall. We are pushing TW to start tankering and investigate what is going on here. They are promising to respond. Our main concern is for them to get a handle on this and ensure that the initial sewage spill is properly resolved and that no other residents are affected. Fingers crossed they get their act together on this.

I have checked my front drive inspection pit this morning and this is quite empty, which is how it should be and suggests the main sewer is running normally. However, this does not accord with TW reporting that the level of the sewer opposite the village hall is high. It may be worth checking the level in your inspection pit.

Cancelled Floods Meeting

I am sure that many of you were disappointed and not a little irritated that the planned January 14^th Floods Meeting was cancelled at very short notice. This was because Cllr Jilly Jordan herself was called away on urgent business and we felt we had no option other than to cancel the meeting. However, we have been hard at work since then and I think this update can provide some optimism for the future.

Our initial thoughts had been to coordinate a new date soon, perhaps in the first half of February. However, since then, David Carroll our local Bucks Cllr, has been successful in arranging an on-site meeting for the DIG with Steve Broadbent, Cabinet Member for Transport who has responsibility for highways drainage. This meet-up happened earlier this week.

This was a very constructive meeting and we learnt from Steve about a program of work initiated by Highways along Warrendene Rd and Bryants.

Program of Work in Warrendene & Bryants

This work will include:

• Cutting back of grass & undergrowth along the edge of the Warrendene ditch. Many of you will have seen this work has already started.
• From 23^rd February work will start using heavy machinery to clear out the ditch along its length. Apparently, this has not been done for 8 years so very timely.
• Road drains will be cleared through to the ditch. At a later point (and subject to capital budget) the road drains will be changed over to larger models.
• The ditch on Hampden Rd (up above the Warrendene crossroads) will be cleared out.
• The section of the Bryants Bottom Rd between Warrendene and Bryants Bottom that is prone to flooding will be dealt with. This will involve clearance of undergrowth at the roadside and the creation of a runoff area.

Natural Flood Management

I have also been able to obtain an update from Andrew Morsley about the Natural Flood Management project. The significance of this is that he expects his field work, analysis and report production work to be completed soon. His intention is to hold a meeting with interested residents at the Hughenden Valley Village Hall very likely in March, which the HVRA DIG will coordinate for him. I am hopeful this meeting will provide us with some answers as to how the flood water from the Hampden area can be alleviated.

The nett result of this progress of events is that we are decided that it will not be beneficial at this stage to organise an early follow-up to the Floods Meeting. We will instead concentrate on a March meeting and we will also invite Jilly Jordan to talk at that meeting. Meanwhile I hope that this update provides some welcome relief regarding the flooding problems experienced as it shows our concerns are being noticed and acted upon. Our thanks to all the residents who have shown interest in this situation and who frequently monitor, report problems to the council and even get their hands dirty doing routine maintenance jobs such as clearing drain tops and blocked grids.

The Stream is Up

Those living in the southern part of Hughenden Valley, typically near the pumping station, will be aware that the stream is rising and starting to run in the watercourses/ditches in our back gardens. As you know, the rising of the stream works its way backwards though the village up to Warrendene. So, if it’s not running with you presently, it likely will soon.

This is a good time for all residents who have the stream run through their garden, to check and clear the watercourse of rubbish, leaves and other detritus. It is your responsibility to ensure that the watercourse is kept clear under the laws of Riparian Responsibilities.

The stream running at this stage of the winter is often a sign that groundwater will be getting into the sewage network and perhaps causing issues with sewage spillages. Thames Water have clearly been visiting the area, doing CCTV surveys and clearing some blockages here and there. We can only hope that the network copes this year, as we don’t really want to see the installation of pumping equipment like happened last year.
