A Bridge of Earn family saw their property swamped by sewage and rainwater as flash flooding struck the village.
The torrential downpour caused flooding on Kintillo Road and Kintillo Place that lapped dangerously at the outskirts of homes lining the road.
Most houses escaped flooding damage as drivers were turned back by emergency services and advised to take other routes.
However, the Ford family, who live at the edge of Kintillo Place overlooking the main road, suffered severe flooding of their garden that was made worse after the rainwater mixed with sewage from nearby drains.
Mum Gillian, who has children aged eight and 15, said the health hazard is a common occurrence for the family because the council have ignored their pleas to carry out any remedy work on the adjacent road.
She said: “My little girl was playing and I was told she couldn’t get out as the sewage comes out of the drains. It gets pretty bad.
“When there’s a really bad downpour it doesn’t go on the road, it just comes into our garden. It flooded all the way into our garage and damaged the lawnmower.”
Gillian claims the family has seen an increase in flooding over the past few years.
She continued: “Since the new flats were built over the road about 10 years ago it’s gotten worse. It covers the whole garden. I want to do things to the garden but we can’t as it’s just a mess.
“It’s just us that gets hit as we’re right on the corner. It’s a horrendous mess and I’m worried every time it rains.
“My husband has phoned the council countless times but nothing gets done. He even put up a fence around the entire house to try and keep the water at bay but nothing stops it.”
A Perth and Kinross Council spokesperson said: “During instances of flash flooding, it is not unusual for flood water to include dilute sewage, as sewers can overflow as a result of a high volume of rain in a very short time.
“Therefore the general public advice that we and other agencies that respond to flooding would give includes avoiding contact with flood water in the interests of public health and safety.
“Issues with public sewers/drains would require the involvement of Scottish Water to address.
“We will be contacting Mrs Ford directly to discuss her concerns.”
Dunbarney Primary also suffered water damage and pupils were sent home early from the school because of the downpour.
The flash flooding affected the central open-plan area and a classroom within the school, while the access to the nursery was also affected by flooding in the playground.
A council spokesperson said: “Work to dry out and clean up inside the building got underway yesterday (Tuesday) and is continuing.
“Once this work is complete, the council will assess if any other repairs are required.”
All pupils had returned to school as normal on Wednesday.
