New survey map for SuDS

The British Geological Survey (BGS) has released a new digital map which it says can help planners, developers and local authorities reduce urban flooding through appropriate use of Sustainable Drainage Systems (SuDS).

The map shows areas where SuDS could be used successfully to filter surface water into the ground using systems such as soakaways, a particular speciality of Tubosider, as well as other infiltration methods.

A demo version of the map is available at According to the BGS, the need for the Infiltration SuDS Map was highlighted by the draft National Standards for Sustainable Drainage released in response to the Floods and Water Management Act 2010.

The standards prioritise the use of infiltration over other sustainable and piped drainage systems – a narrower view than that of Tubosider and manufacturers as a whole.

“Soakaways are an ideal solution in areas where the terrain is suitable, such as predominantly sandy or chalky areas, as we have shown time and again in systems across the UK,” says MD Jim Dwyer.

“But our patented Twinstore design shows how much piped drainage systems can achieve similar goals and also reduce the cost and the footprint. And our other attenuation tanks are specified for contracts right across the board. “Certainly the map has value in identifying areas where infiltration is a viable option , but as ever, it is a matter of horses for courses.”
