Blocked drains

We operate a planned maintenance programme for cleaning highway surface water drains on all the roads we maintain. Where defects or flooding are identified, outside the planned programme, these will be dealt with as necessary.

When you contact us to report a blocked drain, please provide the following information:

  • your name and phone number, in case we need to contact you
  • where the drain is, including the road name and area
  • if it is outside a specific property

Report a blocked drain

This form has 2 pages and will take approximately 2 minutes to complete.

Gully gratings, manhole and drain covers

Gully gratings

You can report any of the following defects:

  • missing
  • broken or dislodged
  • incorrect type

Manhole and drain covers

Please contact us to report a manhole cover that is broken, collapsing, missing, very low or protruding above road level that might be dangerous to road users. We will check the cover and arrange repair work as appropriate.

It is useful to know who the owner of the cover is (for example, phone, gas or water), as it can speed up the process of repair or replacement. If the manhole is owned by a utility company, we will request that they fix the problem within 7 days. Or you can phone the utility company directly to report a defect.

We will come to inspect the site by the end of the next working day, if possible.

If the manhole is owned by a utility company, we will request that they fix the problem within 7 days. Or you can contact them directly to report a defect.

We regularly inspect gully gratings, drains or manhole covers in accordance with our Highway Safety Inspection Manual.

Previously reported issues

If you have already reported a problem, you can check the status of your report using your report reference number here:

Sewage

If a drain is overflowing and the water is very smelly, it is probably sewage. This needs to be dealt with by whoever is responsible for the sewer. This may be the owner of the property or Wessex Water if it is a main sewer.

Wessex Water Leakstoppers – 0800 692 0 692

Wessex Water Emergencies – 0345 600 4 600

If the sewage is coming from a connection to the main sewer or from a cesspit or septic tank, the property owner is responsible and will probably need to contact a plumber or a specialist.

Planned maintenance

We operate a planned maintenance programme for cleaning highway surface water drains on all the roads we maintain.

How often we do this depends on where they are (the classification of the road) and the relative risk of flooding.

  • Gullies in flood susceptible areas will be cleaned every year.
  • Gullies in rural non-flood susceptible areas (outside a 30mph or 40mph speed limit) will be cleaned every two years.
  • Gullies in urban non-flood susceptible areas (inside a 30 or 40mph speed limit) will be cleaned every 4 years.

The planned programme is reviewed and adjusted each year to respond to the changing nature of risk and flooding on the county’s road network.

Where defects or flooding are identified, outside the planned gully cleansing routine, these will be dealt with as necessary.
