Yellow Fish Campaign

We are working with Southern Water, the Environment agency and West Sussex County Council on an important project to help improve and protect the bathing water in our district.

We want to raise awareness amongst the public that road drains and surface water drains are designed to carry rainwater and no other waste - only rain down the drain! These drains direct water into the sea, so disposing of pollutants, such as paint, oils or dog (or human!) waste down these drains is like disposing of them straight into the sea.

The Yellow Fish project is a national campaign, created by the Environment Agency, involving the stencilling of yellow fish symbols beside drains. The symbols will help ensure people understand that the water from these drains goes into our rivers and the sea and that the correct use of these drains is important, if we want to keep our bathing waters clean.

You will start to see these yellow fish popping up around the district, with posters in the vicinity linked to this page.

Bathing water

The Environment Agency test popular bathing waters along our coastline to ensure the water is clean and safe.

Weekly tests are conducted along six key bathing waters along the Arun coastline from May to September. You can see the latest and historical results for each sample site:

Pollution risks

After heavy rainfall, there can be a short-term risk to the bathing water quality around some of our beaches. This is due to water being released from Combined Sewer Overflows (CSOs). 

Southern Water have created a real-time interactive map called Rivers and Seas Watch which allows you to track these CSO releases. 

During times of predicted heavy rain we will display an 'advise against bathing' notice at the following beaches, when the Environment Agency issues a pollution risk warning:

  • Bognor Regis (Aldwick)
  • Bognor Regis (East)
  • Felpham
  • Littlehampton (Coastguards)
  • Pagham

The Environment Agency regulates water pollution and discharges by the water companies.

Bathing water quality at Bognor Regis (Aldwick)

The bathing water quality at Bognor Regis (Aldwick) is currently rated as poor. The Environment Agency have provided more information on the rating and what it means for the bathing water.

Further advice is available from UKHSA on healthy swimming and can be found at Swim healthy - GOV.UK (www.gov.uk)

Drinking water

The drinking water in our district is usually drawn from the mains pipe. Mains water is the responsibility of the water companies in our area.

Usually, water in the eastern half of Arun is supplied by Southern Water.

Water in the western half of the district is supplied by Portsmouth Water.

Drinking water supplied by these companies has to meet strict national standards of quality and safety.

Any questions or concerns about your mains water supply should be sent to your water company, and not to us.

Some properties have a private water supply, which is not provided by the mains. We have to ensure that this water is safe to drink. Find out more about private water supplies.
