The novel use of testing for the presence of newts using DNA found in water samples has seen South East Water win a prestigious national award.

Called eDNA, the water company takes samples from ponds and tests it for Great Crested Newt DNA. The amphibians are a highly protected species and if they are present can impact on pipe laying projects.

The Institute of Water’s National Innovation Award, which recognises revolutionary thinking in the water and sewerage industry, was presented to South East Water at the President’s Dinner and Awards ceremony on Friday 13 May.

South East Water’s Lead Environmental Engineer Steve Newman, said:

“We are absolutely delighted this innovative use of science has been recognised at national level by the Institute of Water.”

“The results from using DNA to detect newts are helping to manage project risks more efficiently, saving us time and money and minimising intervention with the local environment.”

Cathryn Ross, Chief Executive of Ofwat and head of the judging panel, said:

“Not everyone realises that water and sewerage companies have a duty to protect the environment and encourage biodiversity.”

“The potential of DNA testing to be used to detect other protected species is great and could benefit all companies within construction and infrastructure, not just water.”

The method is approved by regulator Natural England and allows the water company to plan any newt protection measures more efficiently before pipe laying activities begin.

Previously, ecologists had to visit all nearby ponds at least four times over several months, working at night, checking for eggs, setting bottle traps and searching for the newts under torchlight. 

As a protected species, Great Crested Newts are closely monitored by Natural England. Companies or individuals who capture or kill or disturb their habitat face a fine and/or custodial sentence.
