East Worthing Wastewater Treatment Works update

Our major maintenance scheme at the East Worthing Wastewater Treatment Works is progressing well.

Since 2012, we have invested £20 million to make improvements to our wastewater treatment works in East Worthing.

On average the works treats up 30 million litres of wastewater every day – rising to more than 71 million litres during wet weather.

This investment is part of on-ongoing programme to provide a long-term solution to problems at the site. This work has included the full maintenance of two nine-ton, 45-foot-long screens. The two screens filter out items such as wet wipes and sanitary products, that have wrongly been flushed down the toilets, from the wastewater that arrives on site.

Further investment is planned for the site and we will continue to keep our customers up-to-date as work progresses.

Sewer jetting

Alongside the work on site, we have jetted a 1,000 meter section of sewer near to the treatment works.

This removed approximately 2,000 tons of rag – items such as grit and non-biodegradable debris such as wet wipes and cooking oil – which were clogging up the 2.2 meter diameter pipe. (This weight is more than 160 double deck buses).

This will improve the flow of wastewater to the treatment works and increase capacity in the sewerage system for stormwater during heavy rain. While this work will not solve the issue of surface water flooding in the area, it’s part of our commitment to help reduce the risk of flooding happening.
