Four dead following explosion at UK WWTP

Four people have died following a major incident at a wastewater treatment plant near Bristol, UK.

Investigations are underway to find out what caused an explosion at Wessex Water in Avonmouth.

The explosion occurred at 11.20am in a silo that held treated biosolids (or sludge) from the sewage treatment process. The sludge is treated in anaerobic digesters to produce renewable energy and fertiliser.

Three employees of Wessex Water and a contractor were killed in the blast and a fifth person was also injured. In a statement, the company’s chief executive Colin Skellett said: “We are absolutely devastated that the tragic incident at our site earlier today has resulted in four fatalities.

“Our thoughts are with the families, friends, and colleagues of those involved.

“We are working with the Health and Safety Executive to understand what happened and why.”
