An inquest has been opened into the death of Robert Geach, aged 54, whose body was found in a sewage filtration tank at Falmouth Docks.
Mr Geach, an employee of South West Water, who lived in Mongleath Road, Falmouth, was found in the tank at the treatment works, at around 8pm on December 30.
Ambulance personnel attempted to resuscitate him before he was taken to the Royal Cornwall Hospital in Truro where he was later pronounced dead.
Funeral arrangements are currently being made by his family, including his widow Sylvia, who is understood to be devastated by her husband’s death, and did not wish to talk to the press at this time.
The Health and Safety Executive is taking part in a police led investigation into the death, which police said was not being treated as suspicious.
A South West Water spokesman said: “Our thoughts are with the employee’s family and friends at this very difficult time”.
They added that the company will be working with the relevant authorities and it would be inappropriate to comment further at this point in time.
A post mortem has been carried out, and an inquest was opened by the coroner, before being adjourned to allow time for a full investigation to be carried out.
