If your private drains or sewers are overflowing, you will need a drainage contractor to deal with any blockage.

See "Yellow Pages" under "Drain and Pipe Cleaning". If you are uncertain if any blockage is in the public or private sewers, the water company should be able to determine this, once on site, then recharge you the cost of any work on the private sewers.

For flooding from the public highway or reporting blocked road gullies or gratings, contact the council.

Wiltshire's local highways service for reporting road, lighting defects and other hazards including flooding and drainage issues.

For issues of flooding on or from the public highway either:

• report on line
• via the app (downloadable to your mobile device)
• contact us on 0300 456 0105.

The local water supply companies are responsible for the repair and maintenance of the water mains, which carry large amounts of water from the treatment works to your street but the property owner is responsible for the pipe which supplies their individual address.
