OPEN water swimmers are being warned to avoid locations across the Sussex coast after sewage was emptied into the water following last week's storm.

The high winds and heavy rain seen last week has led to sewage being emptied at ten popular beach locations over the last 48 hours.

The data is provided by the charity Surfers Against Sewage, which has created an interactive map tracking real-time CSOs (combined sewage overflows) and PRFs (pollution risk forecasts).

Part of the charity's Safer Seas and Rivers Service, the map is also available via a mobile app which provides real-time notifications.

It monitors the water quality at over 400 locations around UK rivers and coastlines.

Alerts are triggered when sewage has entered the water within the last 48 hours.

It also shows which beaches are clear, those which do not have information available due to being out of season, and the sewer systems in the location which are under maintenance and the water company has temporarily disabled alerts.

The Argus: Surfers Against Sewage interactive map tracks real-time CSOs (combined sewage overflows) and PRFs (pollution risk forecasts).

A spokesman for Surfers Against Sewage said: "The regular discharge of raw sewage into our local waters represent an immediate danger to the health of all water users. We advise water users to avoid the area immediately around discharged pipes for at least 48 hours.

"Raw sewage if ingested at best can cause severe sickness, at worst a very harmful infection or even death, all of this in the face of tougher water regulations that are being taken out of the coming up Environment Bill soon to be repeated in Parliament, we urge all MPs to strongly reconsider their current course of action"

These locations have all seen sewage emptied into the water over the last 48 hours:

1. Bognor (Aldwick)

Additionally, there are three surface water outfalls (Norfolk Street, York Road and Albert Road) in the area which may reduce water quality particularly after heavy rainfall. There is also a sewer overflow that discharges into one of these surface water outfalls and two further sewer overflows that discharge into the Aldingbourne Rife.

Last week there was widespread anger after Parliament voted to allow water companies to dump raw sewage into Britain’s rivers and seas. A total of 265 MPs voted in favour, with 202 against.

Among those whose constituencies include the locations of the above beaches who voted in favour of the clause to the Environment Bill were: Bognor Regis and Littlehampton Conservative MP Nick Gibb, and Hastings and Rye Conservative MP Sally-Ann Hart.

MPs who voted against the clause included: Conservative MP for East Worthing and Shoreham Tim Loughton, Conservative MP for Bexhill and Battle Huw Merriman, and Labour MP for Brighton, Kemptown Lloyd Russell-Moyle.
