Sewage leak – updated lines to take from Southern Water

Latest position – Thursday 6 September 2012

Joint statement from the Environment Agency, Adur & Worthing Councils and Arun District Council

The East Worthing sewage treatment works is now back online and discharging fully treated effluent through the long sea outfall in accordance with its Environment Agency environmental permit.  There have been no further discharges of untreated sewage since Monday 3 September 2012 at 2130.

Environment Agency officers have been on site to assess the impact of the sewage as part of an ongoing investigation into what has happened.  Pending the outcome of that investigation, they will look to take appropriate action.

Bathing water samples were taken by Environment Agency Officers on Monday 3 September 2012 when the discharge was occurring and Wednesday 5 September 2012.  Results of these are expected to be received on Friday 7 September.

Adur & Worthing Councils continue to advise people not to swim between Southwick and Ferring, where the Worthing District boundary lies, until full confirmation of the sample results are received.  Once the local authority has these results they will review the decision on swimming.

All authorities are working together to ensure the safety of the public and a return to normal as soon as possible.

The public are advised to check Adur & Worthing Councils websites on Friday for an update at and or @adurandworthing on Twitter or the Adur and Worthing Facebook page.

Any further updates on the situation in Arun will be posted at or @ArunDistrict on Twitter.

Latest Sewage – Statement from Southern Water (as of 4 Sept 12)

Southern Water would like to apologise for the problems at East Worthing Wastewater Treatment Works.

We can confirm we stopped releasing wastewater flows through the emergency, short sea outfall yesterday (the main release was stopped at about 4.10pm – there was another, shorter release, between 8pm and 9.30pm) and the site is now treating and releasing wastewater as it should.

Tankers which were transporting wastewater to other sites for treatment have also been stood down.

Staff have been working 24/7 at the treatment works since the problems began on Saturday night.

The problems began when there was a build-up of non-biodegradable debris which meant we were unable to pump incoming flows through the correct treatment channels. There were also electrical problems at the site.

Diverting wastewater into the sea, via the emergency outfall, was necessary to prevent localised flooding in Worthing.

We worked closely with the Environment Agency and Worthing Borough Council on this issue and thank them for their assistance.

Repair work is continuing on site today and there will be a full investigation into the incident.

We are committed to making improvements at the site and a planned scheme is due to start this autumn.
