Update to Thames Water H Valley & Little Marlow Position Statement

Following the release of the Thames Water Drainage Strategy document for Hughenden Valley and Little Marlow last year, TW have provided us with an update on this, and which can be found on the Documents page on this website.


The report details work carried out over the last year relating to various type of data gathering and surveys, to help future modelling and better enabling the early identification of issues requiring resolution.   

Valley Road Works Update

The works along Valley Road near the bottom of Coombe Lane to improve the road surface water drainage are now complete. We had hoped that the lips to drives affected by the surface water would be raised, but this has not happened so far.


Jonathan Roberts of TFB provided us with a plan of the drain, pipe and chamber work undertaken, which is on the Documents web page. Jonathan also provided an update on the work:

“As you will see we have effectively provided at least a 50% increase in capacity for the existing drainage system within the verge areas. We believe this is essential to remove the surface water as quickly as possible from the areas of carriageway and in particular at the junction of Coombe Lane and Valley Road.

At this junction all flows from these roads are currently channelled into an existing 225mm pipe which has now been doubled to provide the additional capacity required to quickly remove these flows to the area of the ditch. Clearly the existing single 225m carrier pipe with ‘blind’ gully connections in this area was inadequate with the corresponding flows remaining on the carriageway surface.

This arrangement should also assist in releasing the flows within the existing network approaching the junction with Combe Lane from Valley Road and reduce the amount of surface water retained on the carriageway surface.”

Bucks CC Land Drainage Enforcement Policy

Bucks CC have provided us with a link to their Land Drainage Enforcement Policy document. This covers the Council’s responsibilities and powers for the management of watercourses in Bucks. 


In our particular case, HVDIG have been involved with Bucks CC regarding the Hughenden stream, especially where the council is both owner of a section and also the policy enforcer. HVDIG would recommend that residents or businesses in Hughenden Valley who have the Hughenden Stream running through their property should make themselves familiar with this document as it has important implications for them.
