Bovril boats facts for kids
Bovril boats were special ships that helped keep the River Thames clean for over 100 years. From 1887 to 1998, these boats carried London's human waste far out to sea. They took the waste from places like Beckton and Crossness and dumped it into a very deep part of the North Sea called Black Deep. This area was about fifteen miles off Foulness, near the entrance to the Thames Estuary. Similar boats also worked on other rivers, like the Manchester Ship Canal and the River Tyne.

History
A Stinky Problem
In the 1840s, many people started using flush toilets in their homes. This was great for hygiene, but London's old sewers couldn't handle all the extra water and waste. The sewers began to overflow, especially into the River Thames.
In 1858, London faced a terrible summer known as The Great Stink. The river smelled awful because of all the raw sewage. There were also serious outbreaks of a disease called cholera, which spread through dirty water. To fix this, a brilliant engineer named Sir Joseph Bazalgette was asked to redesign London's sewage system.
Bazalgette's new system helped a lot, but it didn't solve everything. The solid part of the human waste, called sludge, still built up on the mud banks further down the Thames. This made the river very polluted.
The Princess Alice Disaster
The serious problem with the river's pollution became clear in 1878. A passenger ship called The Princess Alice sank after hitting another vessel. Many people, including children, lost their lives. When the bodies were recovered, it was discovered that many victims hadn't just drowned. They had also died from swallowing the poisoned, sludge-filled river water. This tragic event showed how dangerous the Thames had become.
Royal Commission
Cleaning Up the Thames
After the Princess Alice disaster, a special group called a Royal Commission was formed in 1882. This group studied the problem and decided that the river needed to be much cleaner. They recommended separating the solid sludge from the liquid sewage. Then, the sludge should be taken out to sea by boat for disposal.
In 1887, the first of these special ships was launched. These boats were designed to pump the sludge on board and then dump it far out at sea. The crews who worked on them nicknamed them "Bovril boats." This was because their brown, thick cargo looked a bit like the beef extract Bovril.
These ships were always kept very clean and well-maintained. They were specially built to carry liquid waste safely. The crews had to make careful calculations to ensure the ships stayed balanced with their heavy, sloshing cargo. Working on these boats offered good pay and steady jobs.
The last three ships in this fleet were named after London areas:
European Union Legislation
A New Way to Handle Waste
In the 1990s, new rules came from the European Union. These rules said that dumping raw sewage at sea was no longer allowed. People also became more worried about sewage polluting beaches and harming the environment.
Because of these new rules and concerns, the Bovril boat fleet was slowly stopped. Many of the ships were taken apart for scrap metal or sold to other companies.
New technology finally offered a better solution. The sludge could now be heated to very high temperatures in special machines called incinerators. This process burned the sludge, and the heat created could even power the incinerator itself. The leftover material was turned into small pellets, which could then be sold as fertilizer for food crops. This new method was much better for the environment.
