Southern water Treatment Works: Visit into the piles of Ragging and FOG’s

Southern water treatment work 2

Clean Seas Please had a tour of the Southern water Treatment Works in Hastings, which cleans the water for Hastings as well as Bexhill.

have a look at our video and read about our visit and the different stages the water goes through here:


The Bexhill and Hastings Wastewater Treatment Works and sludge recycling plant.

Southern Water’s Bexhill and Hastings Wastewater Treatment works serves approximately 150,000 people across Hastings and Bexhill.

The treatment works receives flows of around 922 litres every second during dry weather but this can rise to more than 1,500 litres a second during wet weather.

The wastewater passes through four stages of treatment before being released out to sea.

It takes 8-12 hours to go through the treatment process – around two hours at each of the four treatment stages.

These stages are:

–          Screening and grit removal facilities

–          Primary settlement tanks – called lamellas

–          Aeration tanks

–          Final settlement tanks

For the sludge treatment:

–          Sludge thickening plant

–          Sludge digestion plant

–          Sludge drying and recycling plant

–          Odour control plant

The treatment works runs 24/7, 365 days a year.

The main treatment building houses the inlet works, preliminary treatment and sludge handling facilities.

At the inlet works the water arrives and undergoes treatment through screens which remove fat, oils and grease from the wastewater as well as items such as wet wipes which have been flushed away.

Grit, mainly from roads, is then removed in the aerated grit lanes and taken away for disposal at landfill.

The five primary settlement tanks, called lamellas, are 13 metres long, seven metres wide and seven metres deep. They settle the majority of the remaining solids out of the wastewater – called sludge. This primary settlement process separates the sludge and wastewater into two separate sets of secondary treatment.

Wastewater secondary treatment

The secondary treatment process begins in five aeration tanks, which pump air into the wastewater to encourage bacteria which digests the waste to thrive. The tanks are 13 metres long, seven metres wide and eight metres deep. After the biological process, the water is passed through a final stage of settlement to filter out finer particles of solids before the cleaned wastewater is released to sea through the 1.5 mile long sea outfall.

Sludge treatment

The site’s sludge treatment centre treats about 45 tons of solid waste every day – turning it into an organic soil conditioner.

The first stage in the sludge treatment process is the thickening plant which removes water from the sludge before  From here it passes through large treatment tanks called digesters where bacteria literally eats the waste. Large centrifuges separates the dried sludge, liquid lime is injected to the digested sludge to create a cake that is used as an organic soil conditioner.

Combined Heat and Power Plant

Methane gas produced during the sludge treatment process is converted into electricity by a Combined Heat and Power Plant. It produces enough electricity to power 1,500 homes but the power is actually used to run many of the processes on site. This gas, which would otherwise have been burnt off in a flare, is now being used to produce renewable energy – providing power and heat to the works, with any surplus exported to the National Grid. As well as generating electricity, the CHP plant also recovers heat from the engine and exhaust systems via water from heat exchangers. This water is then used to warm the treatment tanks, helping speed up the bacterial digestion of the waste. The plant reduces the works’ carbon emissions by 3,000 tonnes a year.

Clean seas Please In Priory Meadow, Hastings

It is always good to get to talk to the public about the things they can do to help in everyday life and make an influence on environmental issues. This is your time to help and support our campaign by making changes to how you dispose FOG’S (fats, oils and grease) and think about ragging and what you flush down the toilet! Lets make a different, lets do ours so that Hastings can meet the EU regulations next year!

East Sussex Joint Waste Partnership


Since 2013 Hastings Borough Council, Rother District Council, Eastbourne District Council and Wealden District Council have been working in partnership to improve the environment as well as to save money. All households has been distributed with correct bins for correct wastage to encourage people to recycle. This video shows how the recycling is collected, separated and recycled into new materials.

Remember it takes 450 years for a plastic bag to degrade in water so remember to recycle!!

BEACH CLEAN- Come and join!!!



Hastings Blue Reef Aquarium is appealing for volunteers to take part in a beach clean tomorrow morning/early afternoon.

Staff from Blue Reef have organised the event for Thursday, October 9th on the stretch of beach beside the aquarium and they’re hoping to attract a large number of local people to come along and give their support.

Volunteers will be issued with collecting bin bags, a pair of gloves and a reporting form to record their finds.

“Hastings Council has kindly agreed to provide us with a selection of litter picking tools and volunteers from Clean Seas Please will also be lending a hand,” said Blue Reef’s Leanna Lawson.

“The plan is to meet up at the aquarium at 11am on the day so everyone can be registered and issued with cleaning items, datasheets and beach clean booklets.

“All the rubbish that we collect on the day will be brought back to the aquarium where it will be separated out and individually itemized.

“After that we will recycle as much of it as we possibly can while the rest will be disposed of safely in an extra refuse container” she added.

The event has been arranged as part of the Marine Conservation Society’s ‘Great British Beach Clean’ initiative.

Anyone under the age of 17 who wants to take part will need to be accompanied by an adult. Volunteers are asked to contact Blue Reef to confirm their attendance prior to the event. They should also wear sensible footwear and clothing and bring sunscreen if the weather is hot.

• The beach clean event is due to take place on Thursday, October 9th from 12pm-2pm. Anyone interested in taking part should contact the aquarium direct prior to the event on 01424 718776.
