Flood Protection ‘Just add water!’

Property Protection for Residents in Trevaughan

People living in Trevaughan, Carmarthenshire, are better protected from flooding thanks to a new scheme introduced by Environment Agency Wales.

A number of properties in Trevaughan have experienced flooding in recent years from the River Taf and the Cwm Waun Gron. This led to the Agency carrying out extensive modelling to help better understand the risk to the area.

A COMPANY deployed a pioneering sandless ‘sandbag’ to save equipment worth hundreds of thousands of pounds.

Just 30 FloodSax® protected £360,000 worth of equipment belonging to warehouse floor- grinding company CoGri as torrential floodwater poured towards their premises near Huddersfield in West Yorkshire.

FloodSax® are transformed from being as light as a pillowcase to become as tough and heavy as sandbags. The semi-porous inner liner within FloodSax® contains gelling polymer which absorb water to become taut in just over 3 minutes. Once the water is in there, it stays there and the bags act just like sandbags to keep floods at bay. They are designed so they mould into doorways to keep floodwater out.

CoGri director Lynn Dare said: “The sacks really saved the day. They have been absolutely brilliant. There was a raging torrent coming down the hill but three layers of 10 sacks held it back from our door.”

The company’s four laser grinding machines were kept dry. They are each the size of a Range Rover and cost £90,000.

This was in stark contrast to the year before when traditional sandbags couldn’t prevent flood water getting

About FloodSax®

FloodSax® were invented by Richard Bailey, managing director of Environmental Defence Systems Ltd. Richard has over 20 years experience as a manufacturer and supplier of pioneering

emergency equipment and has earned a global reputation with the Emergency Services and the MOD.

The semi-porous inner liner contains hundreds of absorbent crystals which absorb water to 90% capacity in just 3 minutes. Once the water is in there, it stays there and the bags act just like sandbags to keep floods at bay.

FloodSax®, used as an alternative to traditional sandbags or flood bags, allow everyone to prepare for flooding.

into the site. Lynn added: “Last year we were flooded very badly and put in a £250,000 insurance claim as a result, but this time we’ve been able to function as normal.”

She added: “FloodSax® would be useful to people who don’t have room to store sandbags.”

Twenty FloodSax® fit into a cardboard box so can be ready for action anytime, any place, anywhere unlike sandbags that need vast warehouse storage space, are heavy and expensive to shift involving health and safety issues and specialist manual handling techniques and require huge manpower and lorries to get them to the scene.

A total of 33 properties in Trevaughan were identified as being at risk, and suitable for individual protection measures. This involves placing temporary flood barriers on to the doorways to the properties during a flood incident. These are easy to fit and can be put in place when a flood warning is issued to help prevent floodwaters entering the houses.

Environment Agency Wales’ lead officer for the scheme Rachel Thomas said:

“We hope this scheme will help people living with the threat of flooding in Trevaughan to feel safer in their own homes.

“These individual flood barriers will provide residents with the opportunity to better protect their properties during flooding. As well as delivering them to each property, we carried out the necessary remedial work to ensure they fitted smoothly and squarely into their doorways. We also provided local people with a demonstration on how to use them and are confident that they can install them when there is a risk of flooding.

"We cannot always prevent flooding from happening, but we can help communities prepare for it."
