Drainage and gullies

An important part of any road network is the drainage system which is designed to carry water away from the road surface. Keeping the drains clear from obstructions is important otherwise problems can occur.  Even when a gully is clean and well maintained it will only cope with a certain volume of water at one time, a sudden and heavy downpour can still cause flooding especially if the road is in a low lying area.

To see when an area is scheduled for routine maintenance look at our Gully Cleaning Programme for 2020 (XLSX, 28KB). Please note due to the impact of Covid-19 this is now behind schedule.

Tree roots can cause an issue as they grow through and along the pipes reducing the amount of space for the surface water to be removed. These need to be removed by specialist equipment.

We have one gully tanker which we use to clear our gullies on an estate by estate rota. As there are many drains and one tanker this does take around 4 years to complete fully and we are adding to this each year as more roads are built. We ask people not to park vehicles over the drains when we are working in their street so that the tanker can access the drains.

Flooding hotspots will be cleaned more frequently especially before and after heavy or sustained rainfall.

Here is our Service Statement on gully cleaning, we will:

  • maintain the gullies so they can effectively remove road surface water 
  • respond to blocked gullies and monitor hotspots (Report It here).
  • inspect and clean all drainage grids and grilles annually  
  • inspect, clean and clear all drainage grips (a shallow ditch to help water drain from the road) as part of our annual maintenance
  • clean Council-maintained ditches on an annual basis  these are: Deethe Close (Woburn Sands), Lower Weald, Orchard Way (Stoke Goldington) and Tathall End
  • provide a 24-7 emergency service to respond to drainage emergencies

The water company own and manage the network of public foul and surface water sewers. In Milton Keynes this is Anglian Water. You can contact them at www.anglianwater.co.uk

You can report a blocked road drain using the Report It section on our website or call 01908 252353.
