David Pitblado, of JD Architectural Joinery, said only a private pump installed by neighbouring business Aberhill Metals stopped his workshop being flooded.

"Since this morning, it's been pumping 10 gallons a second," he said on Wednesday afternoon.

Last month, the Fife Herald reported how the failure of a pumping station caused the two businesses to be flooded, resulting in thousands of pounds worth of damage.

At the time, Scottish Water attributed the problem to a blockage caused by materials such as polythene and textiles in the drainage network.

Mr Pitblado said he had reported the latest situation to Scottish Water, but nothing had been resolved.

He added: "To be flooded twice in the space of four weeks, there's definitely got to be something more there than an excess of rain."

A Scottish Water spokesperson said the authority was conducting detailed investigations into the composition of the waste water network at Cupar Trading Estate.

"We are considering the installation of flowmeters at the site to gain data about the flow rates into the system," he said.

"Investigations of the network in the past have highlighted that unsuitable items are causing blockages in the system and these can exacerbate the issues at the pumping station and increase the likelihood of a flooding event.

"We urge local businesses to ensure that unsuitable items are not placed into the waste water system via drains or other means."

The spokesperson added: "We apologise for any inconvenience that local flooding has caused and we are working hard to obtain a permanent and sustainable solution for local businesses."
