Brighton's super sewer
Brighton’s Victorian sewer system is an engineering masterpiece and completely revolutionised waste management. In the 1990s, Brighton's super sewer arrived and eliminated spills with the ability to withstand all but a one in 50 year storm.
A Victorian marvel
Let’s take a trip back to the late 19th century. Brighton was bustling, but the streets were, well…not exactly pleasant. Imagine sewage flowing freely alongside the hustle and bustle. Gross, right? Thankfully, Brighton’s Victorian sewer system changed all of that. This engineering masterpiece was hand-dug, spanning over 40 kilometres, and completely revolutionised waste management in the city. Instead of sewage on the streets, everything was directed underground.
The arrival of the super sewer
Of course, the early days of wastewater management were pretty basic. But fast forward to the 1990s, and things got a whole lot more exciting. Southern Water engineers came up with an innovative solution to tackle Brighton’s sewage issues head-on. They constructed a massive storm-tunnel – five-kilometres long and six-metres wide. It was built to handle a whopping 150,000 tonnes of sewage and rainwater. When it was completed in 1995 (at a cost that would be close to £100 million today!), it was a total game changer. No more sewage spills, on Brighton’s beautiful streets.
A modern-day triumph
But Brighton didn’t stop there. Today, the city is home to a cutting-edge wastewater treatment plant in Peacehaven, located about 12 kilometres up the coast. This £300 million facility treats all of Brighton’s sewage to a level that’s as clean as river water, keeping our seas sparkling and our environment even healthier.
As well as being expensive to build, the Brighton super sewer has other costs. Moving the rain water from Blackrock pumping station between the pier and marina up to Peacehaven used 415,000kwh last year – enough to power the average family home for 66 years or equivalent to the first stage of a SpaceX rocket.
Looking ahead: sustainability and innovation
Even with such energy demands, we’re focused on sustainability. The next step? Investing in nature-based solutions that help manage water flow and reduce energy consumption. Imagine a future where our sewer systems not only keep the city clean, but also work hand-in-hand with nature!
Brighton’s journey from its humble beginnings of rudimentary sewage management to the advanced wastewater treatment we see today is a testament to the city’s commitment to both the environment and public health. It’s a story of resilience, innovation and a greener, cleaner future.
So, next time you’re strolling along the vibrant streets or admiring the Palace Pier, just remember – there’s an amazing underground system working hard to keep Brighton clean.
