A new £7 million project launched by Environment Agency (EA) Wales will protect up to 300 Swansea homes and businesses against flooding.
The scheme is aimed at preventing the River Tawe from breaking its banks and flooding residential areas, business parks and industrial estates in certain parts of the city.
According to environmental chiefs, the river's capacity will be increased in order to accommodate more rainwater and the work will also see several "low spots" raised along the waterway.
Although the UK has been relatively rain-free during the past week or so, small businesses will still be wary of the threat posed by floodwater.
The Met Office confirmed that 2012 was the second wettest on record in the UK and many enterprises were forced to make insurance claims against damaged property.
Indeed, the Association of British Insurers recently revealed that around 486,000 storm and flood damage claims were lodged throughout the course of the year.
However, the EA's Swansea project is one of many initiatives being launched across the UK with the intention of safeguarding organisations and households against the elements.
Steve Brown of EA Wales said the body had been communicating with local firms in the Swansea area to see how they could improve their own flood defences.
"We are working together with the city and county of Swansea to raise awareness of flood risk amongst local people and the local business community, helping them to prepare for and respond to floods," he remarked.
"Over the course of last summer, we visited 500 businesses in the area to establish their level of knowledge about flood risk and this has helped a significant number draw up their own flood plans."
The Swansea scheme is expected to be completed by late 2013 and further landscaping works will take place in 2014.
It is thought that homeowners and businesses in Swansea Vale, Swansea Enterprise Park, Cwrt Llwyn Fedwyn, Tawe Street and Beaufort and Plasmarl Industrial Estates will benefit most from the development.
